Topic: Compiling BRL-CAD

Thusal Ranawaka (Jan 04 2020 at 08:04):

@Sean I claimed a task called 'Compile BRL-CAD with Microsoft Visual Studio Community Edition' so where do I can find the SVN checkout.

Daniel Rossberg (Jan 04 2020 at 12:13):

@Thusal Ranawaka I recommend to have a look at the more general task "[BEGIN HERE] Compile and Install BRL-CAD from source code". If you want to use Visual Studio the work is mainly the same, but the general task has more references in its description.

The "Compile with" tasks are for students, who already compiled BRL-CAD (in the general compilation task) and want to try another compiler/operating system now.

Thusal Ranawaka (Jan 04 2020 at 14:43):

Hey @Daniel Rossberg the task that have you mentioned above seems to be an beginner task so is there any solution for that problem?

Thusal Ranawaka (Jan 04 2020 at 14:46):

Also @Daniel Rossberg I claimed a task called RUN A CODE QUALITY ASSESSMENT ON OGV USING CODECLIMATE I do not understand what to do in codeclimate. Can you tell what to do step wise?

Daniel Rossberg (Jan 04 2020 at 14:52):

Hey Daniel Rossberg the task that have you mentioned above seems to be an beginner task so is there any solution for that problem?

Well, the solution would be to do the Visual Studio task instead. But, can you see the description of the general compilation task with the provided links?

Daniel Rossberg (Jan 04 2020 at 14:53):

Also Daniel Rossberg I claimed a task called RUN A CODE QUALITY ASSESSMENT ON OGV USING CODECLIMATE I do not understand what to do in codeclimate. Can you tell what to do step wise?

Never heard of it before. Let me see ....

Daniel Rossberg (Jan 04 2020 at 14:56):

... did you followed the steps from the task description? They look right straight forward.

Daniel Rossberg (Jan 04 2020 at 14:58):

On Code Climate you should probably do the quality thing (automated code review).

Daniel Rossberg (Jan 04 2020 at 14:59):

as an "Open Source" user.

Thusal Ranawaka (Jan 04 2020 at 15:25):

Hey @Daniel Rossberg do you know how to add BRL-CAD/OGV-meteor repo to Code Climate I can't figure it out.

Daniel Rossberg (Jan 04 2020 at 15:27):

Did you cloned OGV to your own github account?

Thusal Ranawaka (Jan 04 2020 at 15:28):

No. I don't know how to do it.

Daniel Rossberg (Jan 04 2020 at 15:29):

Did you googled for this? Google should provide you a link to the corresponding github help side.

Thusal Ranawaka (Jan 04 2020 at 15:29):

I will try.

Thusal Ranawaka (Mar 02 2021 at 06:33):

@Sean , I checked out the trunk from SVN and trying to compile it using CMake, I entered where the source code is and where to build, but I think I missed something. Because it shows this error, image.png

Sean (Mar 02 2021 at 06:36):

I don't see an error there yet.

Sean (Mar 02 2021 at 06:37):

Are you following the compilation/installation wiki page instructions?

Sean (Mar 02 2021 at 06:37):

be sure to do that...

Thusal Ranawaka (Mar 02 2021 at 06:37):

Yes

Sean (Mar 02 2021 at 06:37):

So what's the next step?

Thusal Ranawaka (Mar 02 2021 at 06:38):

This one know, https://brlcad.org/wiki/Building_from_SVN

Thusal Ranawaka (Mar 02 2021 at 06:38):

Sean said:

Configure the build system with CMake

Sean (Mar 02 2021 at 06:39):

Okay, so have you pressed the "Configure" button?

Thusal Ranawaka (Mar 02 2021 at 06:39):

Yes

Thusal Ranawaka (Mar 02 2021 at 06:40):

It shows this, image.png

Sean (Mar 02 2021 at 06:43):

Scroll that bottom window up, what does it say in there?

Sean (Mar 02 2021 at 06:44):

You'll want to make sure you specified paths to the right folders for source and build

Thusal Ranawaka (Mar 02 2021 at 06:44):

image.png

Thusal Ranawaka (Mar 02 2021 at 06:46):

Sean said:

You'll want to make sure you specified paths to the right folders for source and build

I did it correct, path is direct to "brlcad" folder

Sean (Mar 02 2021 at 06:50):

So did you read the error message?

Sean (Mar 02 2021 at 06:50):

Seems pretty obvious what's wrong...

Thusal Ranawaka (Mar 02 2021 at 06:51):

Yes, it says error at CMakeLIsts.txt

Sean (Mar 02 2021 at 06:52):

Dude seriously... keep reading.

Sean (Mar 02 2021 at 06:53):

There's literally just 4 lines and it says what the problem is in pretty plain terms on one of them.

Thusal Ranawaka (Mar 02 2021 at 06:55):

So, you mean read the CMakeOutput file?

Sean (Mar 02 2021 at 06:55):

....no

Thusal Ranawaka (Mar 02 2021 at 06:56):

This is the whole message,
CMake Error at CMakeLists.txt:85 (project):
Generator

Visual Studio 16 2019

could not find any instance of Visual Studio.

Configuring incomplete, errors occurred!
See also "C:/Users/Thusal Ranawaka/OneDrive/Documents/brlcad/build/CMakeFiles/CMakeOutput.log".

Sean (Mar 02 2021 at 06:57):

So you've apparently not seen this before and that's okay, but you should be able to read what you just pasted and realize what is wrong. What's it saying there?

Thusal Ranawaka (Mar 02 2021 at 06:58):

It says, it can't find any instance of Visual Studio.

Sean (Mar 02 2021 at 06:58):

Bingo!

Thusal Ranawaka (Mar 02 2021 at 06:58):

So, I have to specify it?

Sean (Mar 02 2021 at 06:58):

Do you know what that means?

Sean (Mar 02 2021 at 06:59):

The term "instance" may be confusing you.

Sean (Mar 02 2021 at 06:59):

replace "instance" with "installation" and see if that makes more sense to you.

Thusal Ranawaka (Mar 02 2021 at 07:00):

So, it can't find the installation file?

Sean (Mar 02 2021 at 07:03):

who said anything about a file

Sean (Mar 02 2021 at 07:03):

if you replace "instance" with "installation", what is it saying?

Thusal Ranawaka (Mar 02 2021 at 07:04):

Could not find the Visual Studio in my laptop?

Thusal Ranawaka (Mar 02 2021 at 07:06):

I don't have Visual Studio to my new laptop yet, so, is that the problem?

Sean (Mar 02 2021 at 07:09):

it can't find an installation of visual studio

Sean (Mar 02 2021 at 07:09):

do you know what visual studio is?

Thusal Ranawaka (Mar 02 2021 at 07:10):

Sean said:

do you know what visual studio is?

:face_palm:

Thusal Ranawaka (Mar 02 2021 at 07:10):

I built LiberCAD V3 using Visual Studio

Sean (Mar 02 2021 at 07:11):

Okay... so then even more confusing to me how you got stuck on this error :)

Sean (Mar 02 2021 at 07:11):

cmake is saying it can't find visual studio. that's the compiler.

Thusal Ranawaka (Mar 02 2021 at 07:11):

I never thought that you need VS when you are compiling using CMake.

Thusal Ranawaka (Mar 02 2021 at 07:11):

Sean said:

cmake is saying it can't find visual studio. that's the compiler.

Oh.

Sean (Mar 02 2021 at 07:12):

if it can't find the compiler, it can't prepare the build system

Sean (Mar 02 2021 at 07:12):

if it can't prepare the build system, there's nothing useful it can do yet..

Sean (Mar 02 2021 at 07:13):

so it throws an error telling you it couldn't find a compiler for the environment it's trying to generate

Thusal Ranawaka (Mar 02 2021 at 07:13):

Problem was I thought CMake was a compiler or act as a compiler, since I got less experience in it.

Thusal Ranawaka (Mar 02 2021 at 07:13):

Okay

Sean (Mar 02 2021 at 07:13):

cmake configures the build environment, it's not a compiler

Thusal Ranawaka (Mar 02 2021 at 07:13):

I'll download VS tomorrow, because my wifi is limited.

Thusal Ranawaka (Mar 02 2021 at 07:13):

Sean said:

cmake configures the build environment, it's not a compiler

Okay

Thusal Ranawaka (Mar 02 2021 at 07:14):

Sean said:

cmake configures the build environment, it's not a compiler

Same thing can be done in VS too know?

Sean (Mar 02 2021 at 07:14):

it writes out the files that tell a compiler how and what to compiler, and it supports lots of different compilation environments

Sean (Mar 02 2021 at 07:14):

Thusal Ranawaka said:

Same thing can be done in VS too know?

No.

Sean (Mar 02 2021 at 07:15):

because there are no visual studio project files yet

Sean (Mar 02 2021 at 07:15):

cmake generates the visual studio project files for brl-cad

Thusal Ranawaka (Mar 02 2021 at 07:16):

Yeah

Sean (Mar 02 2021 at 07:16):

cmake could also generate them for a variety of other environments like Mingw or Ninja or Makefiles or ... but it defaults to Visual Studio project files on Windows since they're the most common on Windows.

Thusal Ranawaka (Mar 02 2021 at 07:16):

LibreCAD can, I think because I set both environments and compiled in same Visual Studio

Sean (Mar 02 2021 at 07:16):

notice how the error message even says a specific version

Thusal Ranawaka (Mar 02 2021 at 07:17):

Yes. Studio 2019

Thusal Ranawaka (Mar 02 2021 at 07:18):

I installed Visual Studio yesterday, and I updated my windows, but Windows crashed during the restarting process. So, I had to reset my pc

Thusal Ranawaka (Mar 02 2021 at 07:18):

It deleted VS

Sean (Mar 02 2021 at 07:18):

Thusal Ranawaka said:

LibreCAD can, I think because I set both environments and compiled in same Visual Studio

LibreCAD uses QMake which is a completely different build system generator

Thusal Ranawaka (Mar 02 2021 at 07:19):

Oh, I see.

Sean (Mar 02 2021 at 07:19):

You likely compiled in Qt-Creator

Thusal Ranawaka (Mar 02 2021 at 07:20):

I compiled it in VS, but I had to install Qt and set some paths to it.

Thusal Ranawaka (Mar 02 2021 at 07:21):

That LibreCAD building almost took me 3 weeks work with Florian

Sean (Mar 02 2021 at 07:22):

You're gonna need to work on understanding the toolchains you're working with... what each of them actually does, not just follow a recipe on a web page :)

Thusal Ranawaka (Mar 02 2021 at 07:22):

Yes

Sean (Mar 02 2021 at 07:23):

LibreCAD probably includes MSVC project files pre-generated from QMake, to make it easier for casual contributors

Thusal Ranawaka (Mar 02 2021 at 07:24):

oh

Thusal Ranawaka (Mar 03 2021 at 02:43):

Hey @Sean , slight problem, I generate the code after installing VS and compiled it the "BRLCAD.sln" solution file, and when I search the bin file I can't find mged application.

Thusal Ranawaka (Mar 03 2021 at 02:44):

But others are there like, g-obj, asc-g, etc...

Sean (Mar 03 2021 at 03:55):

You'll want to make sure you compile the ALL_BUILD target

Thusal Ranawaka (Mar 03 2021 at 05:06):

Okay

Thusal Ranawaka (Mar 03 2021 at 05:06):

So, then the tutorial needs to be upgraded.

Sean (Mar 03 2021 at 05:41):

It's a wiki if you'd like to clarify or update it.

Thusal Ranawaka (Mar 03 2021 at 05:56):

@Sean Hey, it still didn't work.

Thusal Ranawaka (Mar 03 2021 at 05:57):

The mged isn't still there in the bin folder.

Sean (Mar 03 2021 at 15:01):

Not a useful statement if you're looking for help.. :)

Thusal Ranawaka (Mar 03 2021 at 15:02):

I compiled ALL_BUILD solution as you said, but still there isn't the mged app.

Sean (Mar 03 2021 at 15:02):

There's so many things you could be doing or not doing that can affect compilation... Did it complete building the solution successfully or did it report error(s)?

Sean (Mar 03 2021 at 15:03):

If it reported errors, you got to look at what they were.

Thusal Ranawaka (Mar 03 2021 at 15:03):

image.png This one know?

Thusal Ranawaka (Mar 03 2021 at 15:03):

Sean said:

It completed with no errors, only some warnings.

Sean (Mar 03 2021 at 15:03):

So you're going to open the BRLCAD.sln solution .. and in there select the ALL_BUILD target.

Sean (Mar 03 2021 at 15:04):

not just select the ALL_BUILD.vcxproj file...

Sean (Mar 03 2021 at 15:05):

It shouldn't make a difference, but that's not something I can say I've tested

Thusal Ranawaka (Mar 03 2021 at 15:07):

Here's what I did, I just double clicked the ALL_BUILD.vcxproj file and it opened in VS with all the files. Then I clicked "Build Solution", it took about 45 minutes to complete and it completed without errors.

Thusal Ranawaka (Mar 03 2021 at 15:14):

It's there in the BRLCAD.sln, I don't know why it isn't building, image.png

Thusal Ranawaka (Mar 03 2021 at 15:28):

@Sean , Build succeeded. image.png

Thusal Ranawaka (Mar 03 2021 at 15:28):

Let's see whether mged is in the bin folder.

Thusal Ranawaka (Mar 03 2021 at 15:30):

Nope. It isn't still there.

Thusal Ranawaka (Mar 03 2021 at 15:31):

Yeah, concerning your question. It says 595 were succedded, another 300 failed.

Thusal Ranawaka (Mar 03 2021 at 15:35):

I think I found the error, image.png

Thusal Ranawaka (Mar 03 2021 at 15:37):

It says it can't find the brlcad_config.h file.

starseeker (Mar 03 2021 at 15:40):

That file should be generated at configure time by CMake. Next question is why isn't it there?

Thusal Ranawaka (Mar 03 2021 at 15:43):

starseeker said:

Yeah

Thusal Ranawaka (Mar 03 2021 at 15:43):

The CMake file generation went well.

Thusal Ranawaka (Mar 03 2021 at 15:44):

I'll try the whole process from the beginning.

Thusal Ranawaka (Mar 03 2021 at 16:06):

Okay, I just wanted you to know. Here is the brlcad_config file. So, I configured and generated the code from CMake from the beginning. image.png

Thusal Ranawaka (Mar 03 2021 at 16:14):

Now I am building the BRLCAD solution with ALL_BUILD targeted.

Thusal Ranawaka (Mar 03 2021 at 16:38):

@Sean Okay, here's the update. So, after the second build, 983 succeeded, 67 failed.

Thusal Ranawaka (Mar 03 2021 at 16:38):

image.png

Thusal Ranawaka (Mar 03 2021 at 16:39):

Noooo, it's not still there.

Thusal Ranawaka (Mar 03 2021 at 16:40):

Thusal Ranawaka (Mar 03 2021 at 16:40):

Sean (Mar 04 2021 at 07:13):

@Thusal Ranawaka brlcad_config.h is not the same thing as brlcad-config

Thusal Ranawaka (Mar 04 2021 at 07:14):

Yeah, it needs to be compiled to become a header file, know?

Thusal Ranawaka (Mar 04 2021 at 07:19):

Okay, the brlcad_config.h file error never occurred after I started the whole process from the beginning. But there's a new error.

Thusal Ranawaka (Mar 04 2021 at 07:19):

Associated with mged

Thusal Ranawaka (Mar 04 2021 at 07:21):

Last time build, 595 succeeded, 370 failed.
But after starting the whole process from the beginning, 983 succeeded, 97 failed.

Thusal Ranawaka (Mar 04 2021 at 07:21):

Still mged app failed.

Thusal Ranawaka (Mar 04 2021 at 07:22):

Thusal Ranawaka said:

image.png

It says it can't a library file.

Sean (Mar 04 2021 at 07:28):

That doesn't look like the first error.

Thusal Ranawaka (Mar 04 2021 at 07:28):

Yeah,

Sean (Mar 04 2021 at 07:28):

You have to find the very first error reported, it's the only one that matters.

Thusal Ranawaka (Mar 04 2021 at 07:29):

I'll try the whole process from beginning.

Sean (Mar 04 2021 at 07:31):

okay

Thusal Ranawaka (Mar 04 2021 at 07:56):

This time, I took a copy of the CMake Generation output to see if the error occurred there.

Thusal Ranawaka (Mar 04 2021 at 07:57):

Now time for compiling ALL_BUILD target.

Sean (Mar 04 2021 at 07:58):

can you post the cmake output here?

Sean (Mar 04 2021 at 07:59):

more than likely, there's some recent change that broke the build on windows that needs to be fixed, but still good to make sure you're not overlooking a cmake failure.

Thusal Ranawaka (Mar 04 2021 at 08:00):

Okay

Thusal Ranawaka (Mar 04 2021 at 08:01):

@Sean CMakeOutput.txt

Thusal Ranawaka (Mar 04 2021 at 08:28):

@Sean Okay, here are the results. It's the same error before. It can't find that .lib file.

Thusal Ranawaka (Mar 04 2021 at 08:28):

983 succeeded, 97 failed. Build Failed.

And during the build I saw, that stating "mged.vcxproj" file failed.

Thusal Ranawaka (Mar 04 2021 at 08:40):

Here's the VS Output file, VSOutput.txt

Sean (Mar 04 2021 at 16:08):

@Thusal Ranawaka So again... you have to find the FIRST error, and what you screenshot was not the first error so it's useless.

Sean (Mar 04 2021 at 16:09):

Fortunately, you posted the VS Output file, which does make it easy to find the first error. To my eyes, this looks like the first error:

104>RC : fatal error RC1107: invalid usage; use RC /? for Help
104>
104>Done building project "tk.vcxproj" -- FAILED.

And that's a non-trivial failure that @starseeker may need to help with. Looks like libtk failed to compile, so everything that uses it also fails.

starseeker (Mar 04 2021 at 16:51):

rc is the resource compiler... I'm building on windows myself, I'll see if I can reproduce.

starseeker (Mar 04 2021 at 16:54):

@Thusal Ranawaka which version of CMake are you using?

Thusal Ranawaka (Mar 05 2021 at 01:22):

starseeker said:

Thusal Ranawaka which version of CMake are you using?

@starseeker CMake 3.20.0-rc2

starseeker (Mar 05 2021 at 01:41):

Hmm. I just built successfully - can you try with 3.19.6?

Thusal Ranawaka (Mar 05 2021 at 01:43):

Okay

starseeker (Mar 05 2021 at 01:44):

Hopefully that will give us an idea if CMake 3.20 is changing anything about their RC support...

Thusal Ranawaka (Mar 05 2021 at 01:44):

Do you think it was an error that occurred when I was exporting the repo from Tortoise SVN?

starseeker (Mar 05 2021 at 01:45):

You mean checking it out with TortoiseSVN? I doubt it - try running an update on your checkout folder to see if there is anything missing.

Thusal Ranawaka (Mar 05 2021 at 01:46):

starseeker said:

Yes

Thusal Ranawaka (Mar 05 2021 at 01:55):

I did an update.

Thusal Ranawaka (Mar 05 2021 at 01:55):

image.png

starseeker (Mar 05 2021 at 02:01):

OK, you're probably good there then. That's why I suggested trying the stable CMake - it's possible that they've tweaked how RC compilation logic is generated in the newer CMake, and it might be causing issues.

Presumably it's the wish.rc file being added by src/other/tk/CMakeLists.txt that's causing the issue...

Thusal Ranawaka (Mar 05 2021 at 02:02):

Hmm

Thusal Ranawaka (Mar 05 2021 at 02:02):

I just finished Configuring and Generating.

starseeker (Mar 05 2021 at 02:03):

OK, try building the "wish" target

starseeker (Mar 05 2021 at 02:03):

We don't need to try the full build until we see if that works.

Thusal Ranawaka (Mar 05 2021 at 02:05):

Okay.

Thusal Ranawaka (Mar 05 2021 at 02:06):

This one know, image.png

starseeker (Mar 05 2021 at 02:07):

Yes

Thusal Ranawaka (Mar 05 2021 at 02:07):

No, build failed.

Thusal Ranawaka (Mar 05 2021 at 02:07):

It's the tk file again.

Thusal Ranawaka (Mar 05 2021 at 02:07):

image.png

starseeker (Mar 05 2021 at 02:09):

Ah. OK, first thing - open the BRLCAD project or the ALL_BUILD project, not the wish project.

Thusal Ranawaka (Mar 05 2021 at 02:09):

Okay. Did it

starseeker (Mar 05 2021 at 02:10):

Once you've opened that, look for that wish target in the main project. Right now it's trying to build deps it doesn't know about.

starseeker (Mar 05 2021 at 02:10):

Try building it from there - it should build the tk library first, then try to build wish.

Thusal Ranawaka (Mar 05 2021 at 02:10):

starseeker said:

Once you've opened that, look for that wish target in the main project. Right now it's trying to build deps it doesn't know about.

That's how I did it.

Thusal Ranawaka (Mar 05 2021 at 02:11):

I searched wish in BRLCAD.sln project.

starseeker (Mar 05 2021 at 02:11):

Hmm. OK. Did you run "Build" or the build only this project option?

Thusal Ranawaka (Mar 05 2021 at 02:12):

I ran Build, because there was no "Build only"option

starseeker (Mar 05 2021 at 02:13):

If you right-click on the "wish" target, there's usual a series of options in the menu that pops up.

Thusal Ranawaka (Mar 05 2021 at 02:13):

That's how I did it.

starseeker (Mar 05 2021 at 02:14):

OK. Can you try building the "tk" target?

Thusal Ranawaka (Mar 05 2021 at 02:14):

Ah yes, there's build only option. In the Project only tab.

Thusal Ranawaka (Mar 05 2021 at 02:14):

starseeker said:

OK. Can you try building the "tk" target?

Only that target?

starseeker (Mar 05 2021 at 02:15):

No, just try "Build" on the tk library. Let's see if that works.

Thusal Ranawaka (Mar 05 2021 at 02:16):

It failed too. image.png

starseeker (Mar 05 2021 at 02:17):

Ah, right - I forgot, tk also has a .rc file.

Thusal Ranawaka (Mar 05 2021 at 02:18):

Yeah

starseeker (Mar 05 2021 at 02:18):

OK, under Source Files for the tk target, see if you can find tk.rc listed

Thusal Ranawaka (Mar 05 2021 at 02:22):

I am looking at the tk folder right now, but can't find a tk.rc file listed.

starseeker (Mar 05 2021 at 02:23):

So one other thing you can try quickly is to comment out line 673 in src/other/tk/CMakeLists.txt by prefixing it with "#" and re-running CMake, then trying the tk build again.

starseeker (Mar 05 2021 at 02:23):

I don't know why that would cause an invalid syntax issue, but it's a quick test to rule it out

Thusal Ranawaka (Mar 05 2021 at 02:25):

Hey there isn't a CMakeLists.txt file in that tk folder.

starseeker (Mar 05 2021 at 02:25):

In your TortoiseSVN checkout

starseeker (Mar 05 2021 at 02:25):

Not in the build directory.

Thusal Ranawaka (Mar 05 2021 at 02:26):

starseeker said:

You mean the Checkout folder, know?

starseeker (Mar 05 2021 at 02:26):

yes

Thusal Ranawaka (Mar 05 2021 at 02:27):

Yeah, I checked there.

Thusal Ranawaka (Mar 05 2021 at 02:27):

image.png

starseeker (Mar 05 2021 at 02:28):

That's the build directory - you're in brlcad/build

starseeker (Mar 05 2021 at 02:28):

You want brlcad/src/other/tk

Thusal Ranawaka (Mar 05 2021 at 02:31):

This correct know? image.png

starseeker (Mar 05 2021 at 02:31):

Yes.

starseeker (Mar 05 2021 at 02:32):

Let's see if that changes anything.

Thusal Ranawaka (Mar 05 2021 at 02:32):

starseeker said:

You want brlcad/src/other/tk

Sorry. I totally forgot that I was on the build folder.

starseeker (Mar 05 2021 at 02:32):

So re-run CMake to regenerate the Visual Studio build files.

starseeker (Mar 05 2021 at 02:32):

The re-open Visual Studio and try the tk target again.

starseeker (Mar 05 2021 at 02:33):

If we still get the same error message, the next question is whether RC is correctly installed on your system.

Thusal Ranawaka (Mar 05 2021 at 02:33):

ok

starseeker (Mar 05 2021 at 02:38):

According to this, you need the SDK: https://discourse.cmake.org/t/cmake-rc-support-ninja/2883/7 (You're not using Ninja to build, but the RC tool is what we're trying to run on those .rc files)

Thusal Ranawaka (Mar 05 2021 at 02:39):

Success!

Thusal Ranawaka (Mar 05 2021 at 02:39):

image.png

starseeker (Mar 05 2021 at 02:40):

Does wish build?

Thusal Ranawaka (Mar 05 2021 at 02:41):

Yes.

Thusal Ranawaka (Mar 05 2021 at 02:41):

image.png

starseeker (Mar 05 2021 at 02:41):

Strange. OK, try the all-up build.

Thusal Ranawaka (Mar 05 2021 at 02:43):

Building now

starseeker (Mar 05 2021 at 02:43):

That line was added in r76799 so the wish.exe.manifest file could be found. I wonder why it's suddenly a problem now...

Thusal Ranawaka (Mar 05 2021 at 02:45):

Hmm

Thusal Ranawaka (Mar 05 2021 at 02:46):

So, is this .rc file essential for this mged build? or can mged run without that?

starseeker (Mar 05 2021 at 02:46):

If I remember correctly, it's essential...

starseeker (Mar 05 2021 at 02:47):

Can you launch a Visual Studio Command Prompt?

starseeker (Mar 05 2021 at 02:48):

Also, if you look in the build directory for the CMakeCache.txt directory, what variables does it have set there that match the CMAKE_RC_* pattern?

Thusal Ranawaka (Mar 05 2021 at 02:57):

I'll have a look after the build

Thusal Ranawaka (Mar 05 2021 at 03:07):

starseeker said:

@starseeker
//RC compiler
CMAKE_RC_COMPILER:FILEPATH=rc

starseeker (Mar 05 2021 at 03:07):

Did the build fully succeed?

Thusal Ranawaka (Mar 05 2021 at 03:07):

starseeker said:

Yes

Thusal Ranawaka (Mar 05 2021 at 03:07):

0 errors

starseeker (Mar 05 2021 at 03:08):

/me blinks. OK, can you run mged, archer and bwish?

Thusal Ranawaka (Mar 05 2021 at 03:09):

Yep

Thusal Ranawaka (Mar 05 2021 at 03:09):

image.png

Thusal Ranawaka (Mar 05 2021 at 03:10):

It works

Thusal Ranawaka (Mar 05 2021 at 03:15):

So, build successful or do we have to look at .rc file?

starseeker (Mar 05 2021 at 03:16):

OK. I'll comment out that line in the repo once I can verify a similar result here (at least until I can understand why we might need to put it back in, and how to do so without inducing breakage)

Thusal Ranawaka (Mar 05 2021 at 03:16):

Okay

Thusal Ranawaka (Mar 05 2021 at 03:16):

Let me know after you have done that.

starseeker (Mar 05 2021 at 03:17):

I really don't understand why that line should break your build - if you can do it quickly, can you re-add it, re-configure CMake again and show me the CMAKE_RC_* variables from the CMakeCache.txt file?

starseeker (Mar 05 2021 at 03:17):

I'd like to see what the difference is

Thusal Ranawaka (Mar 05 2021 at 03:18):

starseeker (Mar 05 2021 at 03:18):

I'm curious what they were before commenting out the CMAKE_RC_FLAGS variable in src/other/tk/CMakeLists.txt

Thusal Ranawaka (Mar 05 2021 at 03:20):

if (MSVC)
set(TK_SRCS ${TK_SRCS} win/rc/tk.rc)
#set(CMAKE_RC_FLAGS /i${CMAKE_CURRENT_BINARY_DIR})
endif (MSVC)

Thusal Ranawaka (Mar 05 2021 at 03:20):

This one?

starseeker (Mar 05 2021 at 03:24):

yes

starseeker (Mar 05 2021 at 03:25):

removing that fixed your build, so I'm wondering what about it was causing breakage...

Thusal Ranawaka (Mar 05 2021 at 03:25):

Hmm

starseeker (Mar 05 2021 at 03:26):

As far as I know, /i and the include directory is valid syntax for RC...

Thusal Ranawaka (Mar 05 2021 at 03:27):

One single variable caused a whole build to fail.

starseeker (Mar 05 2021 at 03:28):

That's not so unusual in and of itself, but I'm wondering why that particular insertion caused a failure. Your error message seemed to indicate the /i flag was invalid, which is why I'm curious about what ended up in the CMakeCache.txt file with it enabled.

starseeker (Mar 05 2021 at 03:37):

I went ahead and committed the commenting out of that variable - if it breaks my build locally we'll have to figure out something else, but in the meantime you should be good to go.

starseeker (Mar 05 2021 at 03:37):

(I'm done for the night - back tomorrow.)

Thusal Ranawaka (Mar 05 2021 at 03:37):

Okay. Good Night!

What areas won't work in MGED?

Thusal Ranawaka (Mar 05 2021 at 13:59):

Did you check?

starseeker (Mar 05 2021 at 14:03):

It seems to have built. I'll test functionally later, but for now it looks like commenting out that line can stand.

Thusal Ranawaka (Mar 05 2021 at 14:04):

Okay

Thusal Ranawaka (Mar 07 2021 at 13:55):

@starseeker Hey, were you able to regenerate the rc error in your local machine?

Thusal Ranawaka (Mar 07 2021 at 13:57):

And why does this build folder took so much space in a Windows laptop? (just asking). The build folder is almost 8GB in my laptop. And the repo is almost 400MB.

starseeker (Mar 07 2021 at 14:40):

I haven't tried to reproduce it - as long as everyone is building right now, that's enough. We're about to switch how we build 3rd party dependencies, and when we do we'll be using Tcl/Tk's own build system instead of our CMake. If we still see an issue after that, we should be able to enlist the community's help in addition to our own efforts.

Thusal Ranawaka (Mar 07 2021 at 14:45):

Okay. Thanks!

Sean (Mar 08 2021 at 14:38):

@Thusal Ranawaka BRL-CAD is big and when yo compile, the compiler has all sorts of intermediate files it has to generate. They take up much more space than the source code itself. Also, I don't think that repo size you said is correct -- BRL-CAD sources alone are more than 400MB. Should be in the 1-2GB range.

Yeah, I only checked out the trunk

Thusal Ranawaka (Mar 10 2021 at 13:19):

Hey, So, if the migration to GitHub is done. I can try out my build from GitHub now, know?

starseeker (Mar 10 2021 at 13:19):

What do you mean?

starseeker (Mar 10 2021 at 13:19):

You can clone and build it, certainly...

Thusal Ranawaka (Mar 10 2021 at 13:19):

Yeah

starseeker (Mar 10 2021 at 13:20):

Or fork, clone, build if you like

Thusal Ranawaka (Mar 10 2021 at 13:20):

So, when cloning I have to clone the whole repo know?

Thusal Ranawaka (Mar 10 2021 at 13:20):

Because there isn't a trunk there.

starseeker (Mar 10 2021 at 13:21):

The new "trunk" is called "main"

Thusal Ranawaka (Mar 10 2021 at 13:21):

I see.

starseeker (Mar 10 2021 at 13:23):

However, git works a bit differently than subversion - a clone is going to download the full repo history. Fortunately, Git ended up being much more compact than SVN when it comes to storing that history - your Git clone shouldn't end up being too much larger than your SVN checkout.

Thusal Ranawaka (Mar 10 2021 at 13:23):

Now the Wiki needs an update too, about compiling BRL-CAD from Source using GitHub for newbies.

Yeah. For that, I won't delete the SVN Checkout, I will rename it and store it in my laptop safely, to use when necessary.

starseeker (Mar 10 2021 at 13:25):

It does. There's quite a lot of our documentation that will need to be updated. I'm currently making sure the build itself is working properly (our distcheck logic uses the version control system to get some information, and while I prototyped out a version using Git I now need to make sure it works in the final setup.)

Thusal Ranawaka (Mar 10 2021 at 13:25):

Okay. Good Luck!

starseeker (Mar 10 2021 at 14:42):

Blast. @Sean - something I never noticed until now. The tkhtml compilation apparently depends on having populated rcsid strings, so my stripping of those from the history during the conversion broke the tkhtml build.

starseeker (Mar 10 2021 at 14:43):

I fixed it in main, but that means older builds will trip on the tkhtml build.

Thusal Ranawaka (Mar 10 2021 at 16:30):

So, you found the error?

starseeker (Mar 10 2021 at 16:31):

Yes. Latest main will build now. Working on a solution for older commits.

Thusal Ranawaka (Mar 10 2021 at 16:31):

Okay. Great

Thusal Ranawaka (Mar 11 2021 at 02:37):

Excellent.

starseeker (Mar 16 2021 at 16:52):

@Thusal Ranawaka I think I figured out the CMAKE_RC_FLAGS issue - that flag is used/needed when the Ninja generator is used. Once the repo is live again, I'll commit the proper fix.

Okay. Great

I wonder if gold or mold (linkers) would noticeably speed up compile time :thinking:

The documentations said to change these flags to this:

BRLCAD_BUNDLED_LIBS=ON

I only found one of this flag:
BRLCAD_BUNDLED_LIBS=ON

But no easy way to change the flag and the other two were not present at all. Do I have to run an external CMake? I have the latest CMake installed and all my libraries are up to date. I'd rather use the one inside of Visual Studio because I kind of hate the external CMake. Didn't really expect this to build on the first try. I was surprised that it auto configured everything automatically. So I figured give it a try.

Daniel Rossberg (May 22 2023 at 14:58):

The error looks like https://developercommunity.visualstudio.com/t/cannot-build-cmake-solution-after-update-to-169/1367002. If updating Visual Studio does not help, using the stand-alone CMake should be a work-around.

Daniel Rossberg (May 22 2023 at 15:01):

Regardind the CMake flags: The only one I'm setting is CMAKE_INSTALL_PREFIX. I set it to a directory, where I can write in without becoming an administrator. In your case for example C:/Users/jeram/bin/brlcad?

Daniel Rossberg (May 22 2023 at 15:05):

The BRLCAD_ENABLE_STRICT is an "Advanced" flag. You have to hit the "Advanced" switch in the CMake GUI to see it.

The BRLCAD_ENABLE_COMPILER_WARNINGS flag had to be set (created) by you.

Sean (May 22 2023 at 20:15):

Few more changes to push, and still sans ogl, but Mac build is restored...
