02:15.47 starseeker is very tempted to dispense with the custom timing code now that CMake has added support for string(TIMESTAMP)
02:15.57 starseeker that has been one long portability headache
02:21.23 starseeker figures once Debian stable gets 2.8.11 as its default it's toast...
02:22.56 starseeker blessing: for tutorials, I'd start with http://brlcad.org/w/images/c/cf/Introduction_to_MGED.pdf
02:23.27 starseeker it's a bit dated - there are a couple commands with incorrect syntax - but it's generally still applicable
02:31.19 starseeker still thinks http://www.cmake.org/Wiki/CMake_Version_Compatibility_Matrix is one of the best examples he's ever seen of open source contributed documentation... spectacularly useful

08:29.31 blessing Hi Everyone I have been practicing mged tool following the introduction to mged recommended by brlcad and starseeker but Nothing appears when i draw a sphere
08:29.52 blessing The steps were
08:30.03 blessing mged sphere.g
08:30.43 blessing changed units to mm : units mm
08:31.43 blessing then make sph1.s sph and finally draw sph1.s
08:32.22 blessing Nothing still happens as im still in mged
08:32.53 blessing should i just continue typing the commands or something is wrong?

09:43.51 stefanmirea Hi blessing, try to zoom out a few times or use View -> Default.
09:45.24 blessing hi stefanmirea, im not sure i understand you
09:45.49 blessing im running from terminal
09:46.08 blessing i dont know what to zoom
09:46.56 stefanmirea You don't have a graphics window?
09:47.23 blessing no when i start mged no other window is displayed
09:47.36 blessing im still in my terminal
09:48.04 stefanmirea Well, that seems weird.
09:48.12 stefanmirea What command did you use to run mged?
09:49.53 blessing from the manual i did mged sphere.g
09:50.41 blessing and i got this prompt
09:50.45 blessing BRL-CAD Release 7.25.0 Geometry Editor (MGED)
09:50.45 blessing <PROTECTED>
09:50.45 blessing <PROTECTED>
09:50.45 blessing attach (nu|txt)[nu]?
09:56.27 stefanmirea That is the classic mode, I don't know what to say, it looks like your mged is an alias to mged -c.
09:56.31 stefanmirea Try "type mged".

20:55.41 brlcad blessing: it sounds like your display isn't working right if it didn't show you the sphere you just drew
20:56.00 brlcad "make sph sph" should display a sphere wireframe
20:56.08 brlcad run "rt" to see it in another window shaded
20:57.44 brlcad the attach prompt indicates that it did not compile the X11 interface -- make sure you have the x11 development headers installed, delete your CMakeCache.txt file, and redo the build (make sure X11 is enabled in the summary when you run cmake)
20:58.02 blessing brlcad, running "rt" says a view does not exist
20:58.25 brlcad did you precede it with make sph sph?
20:58.32 brlcad or draw
20:59.04 blessing yes i try with make and draw
20:59.17 brlcad eh?
20:59.25 brlcad that wasn't my question :)
20:59.38 brlcad did you run "make sph sph" immediately before running "rt"?
20:59.39 *** join/#brlcad teepee (~teepee@gateway/tor-sasl/teepee)
21:00.57 brlcad and thinking it through, rt certainly isn't going to show you a window either if you didn't have X11 enabled
21:01.33 brlcad you can run "rt -o file.png" and open that png file with an image program
21:03.32 blessing It keep saying a view does not exixt. I think i should delete the CMakeCache.txt file and redo make as recommended
21:03.47 blessing hoping it works
21:03.59 brlcad you'll have to rebuild regardless
21:04.13 brlcad "attach (nu|txt) [nu]?" is wrong
21:04.22 brlcad you should see more options
21:04.37 brlcad but nothing is going to change if you just delete and rebuild
21:04.43 brlcad here's what you should do:
21:05.17 brlcad 1) go to your build dir, run "cmake ." ... and read the summary output, notice where it tells you that X11 is disabled
21:05.47 brlcad 2) install the X11 devel headers (see the /wiki/Compiling page for lots of things you were supposed to install)
21:06.14 brlcad 3) delete the CMakeCache.txt file, rerun cmake, and rerun make
21:07.02 brlcad when you rerun cmake ... pay attention to the summary output!!! if it doesn't say X11 is enabled, you still have a problem
21:07.13 brlcad make sense?
21:08.22 brlcad you want to see: X11 support (optional) ................: ON
21:09.02 blessing i think the steps are clear even though i dont understand what's going happening. let me just give it a try and report back
21:09.13 brlcad you'll also want OpenGL ON if you need to do anything with archer
21:09.39 brlcad when you run cmake .. it tests to see what is available on your system, what libraries, what headers, what tools
21:09.59 brlcad to compile against a library, you need that library and that library's headers
21:10.28 brlcad you almost certainly don't have headers installed for X11, which is your display system .. so you can't compile X11 windowed applications
21:11.14 brlcad the brl-cad build system doesn't care .. we're portable and mged was technically running, just without a window .. there's lots you could do with that, but makes learning/using it harder if you're new
21:12.17 brlcad you obviously can RUN x11 applications -- that means you have at least some of the X11 libraries installed (libX11, libXi, libXt, libXext, etc)
21:12.29 brlcad but you can't COMPILE x11 applications without the x11 headers, which you have to install
21:12.37 brlcad better?
21:13.22 ``Erik should this process be a wikipage that notify or ibot can have the link to? :)
21:13.30 brlcad if it's still unclear, ask questions ... most people here can probably explain things and answer questions better ;)
21:13.44 brlcad ``Erik: it's already a wiki page
21:14.15 brlcad but the wiki page is intentionally concise to be simple, doesn't explain how compiling works
21:14.44 brlcad or cmake or the relationship of *-devel packages with lib packages or ...
21:15.06 brlcad so yeah, blessing ... please do ask questions, don't be shy ;)
21:15.23 brlcad one only learns by failing
21:17.37 blessing I just installed the x11 headers and Im following the steps mentioned
21:17.54 blessing will report if it still fails

22:52.01 blessing Now I have two windows. MGED command and Graphics Window! thanks brlcad
22:52.23 blessing I can now continue my tutorial
23:00.43 ``Erik w00t
23:04.13 ``Erik brlcad: mebbe a good 'new contributor' task would be to set up a string of wiki pages as a 'choose your own adventure' troubleshooting/installing guide? each page is a step with a set of "if you see, then click" links after? (or build the "big honkin directed graph" as a webapp or something... wizard style)
