starseeker (Aug 31 2025 at 16:29): starseeker (Aug 31 2025 at 16:29):Does anyone have a very new MacOS + new Xcode (I think 16.4) set up where they can debug? I think the GitHub runners bumped versions on something recently, and after working around a couple compile errors I'm getting some sort of weird "process killed" failure when trying to run things after the compile completes. It feels a little like the early problems I had getting bext to work on OSX when I didn't know about the issues path updates cause with code signing, but I'm not sure if that's what's happening again. If anybody can reproduce and debug (right now I can do so only on the CI runners, which isn't ideal for iterating, to say the very least) it would be helpful.
Pavel Jansa (Sep 14 2025 at 06:51):Hi. I have MacOS 15.6.1, Xcode 16.4, XQuartz 2.8.5 and make cmake 3.31.7. I cloned git repo (7.42.1) and in build directory executed cmake .. -G Xcode. It ended like this: https://pastebin.com/hkV9fxPT
If you give me detailed instructions I can share debugging reports but I am not able to figure out configure and compile issues by myself.
Pavel Jansa (Sep 14 2025 at 08:44):OK, switching to cmake 4.1.1 got me a bit closer. Configuration ends up well, but generating build files fails in this manner: https://pastebin.com/kgcWJrCv
Pavel Jansa (Sep 14 2025 at 09:42):build.log
Hmm this is another attempt to build.

Pavel Jansa (Sep 14 2025 at 12:18):To to clarify (or add to) the mess I made above:
cmake .. -G Xcode -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=$HOME/brlcad-dev

install.log
Pavel Jansa (Sep 27 2025 at 17:17):Ok, this doesn't have to do anything with Xcode, but it leads to successful build on macOS 15.7. First configure:
cmake .. \
-DCMAKE_BUILD_TYPE=Release \
-DBRLCAD_ENABLE_STEP=OFF \
-DBRLCAD_ENABLE_ASSETIMPORT=OFF \
-DBRLCAD_ENABLE_GDAL=OFF \
-DBRLCAD_DISABLE_BINARY_PLUGINS=ON \
-DX11_INCLUDE_DIR=/opt/X11/include \
-DX11_LIB_DIR=/opt/X11/lib \
-DCMAKE_PREFIX_PATH=/opt/X11
leads to success. then
make &&make install
Thanks for sharing your build configuration @Pavel Jansa ... very interesting that you had to turn those three off to get it to succeed, or if it was the binary plugins.
Pavel Jansa (Oct 08 2025 at 16:07):Those three were the sources of troubles. Especially step. Anyway in a few days I will give it a go with different config and share the results.
Pavel Jansa (Oct 11 2025 at 13:06):This was an attempt to build succesful configuration for xcode
cmake .. \
-G Xcode \
-DCMAKE_BUILD_TYPE=Release \
-DBRLCAD_ENABLE_STEP=OFF \
-DBRLCAD_ENABLE_ASSETIMPORT=OFF \
-DBRLCAD_ENABLE_GDAL=OFF \
-DBRLCAD_DISABLE_BINARY_PLUGINS=ON \
-DX11_INCLUDE_DIR=/opt/X11/include \
-DX11_LIB_DIR=/opt/X11/lib \
-DCMAKE_PREFIX_PATH=/opt/X11
Here goes the log.
cmake_xcode.log
This was the build command:
xcodebuild -project BRLCAD.xcodeproj
And this is how it failed.
xcodebuild.log
If you need more info, just tell me how to get it and wait a while :)

Think I fixed this one. Looked like the wrong var was used.
starseeker (May 08 2026 at 02:35):@Sean I don't doubt there's a lot more to do to get it actually going with aqua Tk, but I've got a proof-of-concept Tk osmesa dm backend at https://github.com/BRL-CAD/brlcad/tree/tkswrast that should lay the groundwork. It wouldn't be a proper OpenGL accelerated backend, but it's using TkPhoto so in principle it could be made to work.
Sean (May 08 2026 at 13:16):I can try to give the branch a test if you think it’s ready to try?
starseeker (May 08 2026 at 13:59):It seems to work on Linux, at least at a basic level, so it might be worth a go
starseeker (May 08 2026 at 14:00):I'm not sure where our bext Tk build and FindTCL.cmake logic is with Aqua though. For that matter, we might have to upgrade beyond 8.6 to get the best modern OSX behavior

Yikes. Well, boost we can probably get rid of but the rest are all basically legit
