@vami, I could not duplicate the issue. Did you rebuild cbang-git before trying to build camotics-git?

UPDATE: I see now that upstream has implemented your fix, which is why I could not duplicate the issue. Thanks for your help!

Hello,

Recent compilation of camotics is failing on ArchLiux; I got an error with the following include file:

In file included from src/camotics.cpp:23:
/opt/cbang/include/cbang/ApplicationMain.h:38:10: fatal error: cbang/os/win/Win32EventLog.h: No such file or directory
   38 | #include <cbang/os/win/Win32EventLog.h>

compilation terminated.
scons: *** [build/camotics.o] Error 1
scons: building terminated because of errors.
==> ERROR: A failure occurred in build().
    Aborting...

I have notified upstream about the issue. In the meanwhile following workaround can be applied: /opt/cbang/include/cbang/ApplicationMain.h tries to include /opt/cbang/include/cbang/os/win/Win32EventLog.h. By placing it in #ifdef compilation runs fine. Here is a patch to work fix it:

Hope this helps.

It works for me now, thanks a lot!

I fixed the packaging on cbang-git. Try rebuilding cbang-git with the latest PKGBUILD. That should fix it.

After building cbang-git, the build for camotics-git is failing with the following error:

Could anyone provide some help? Thank you very much!

Anyone who encountered the error should rebuild the package - cbang-git + camotics-git https://aur.archlinux.org/packages/cbang-git#comment-925246

I'm working on this, but I think you are going to have to re-build v8-r against the latest icu. It takes a long time to re-build, so I won't know for sure if there are any other issues until it is done. After re-building v8-r, build cbang-git then camotics-git.

pkgconf is part of the core arch installation, so it doesn't need to be listed as a dependency in the PKGBUILD.

Are you running an arch derivative or pure arch?
Did you try rebuilding freecad?
What do the following commands produce?

strings /usr/lib/libstdc++.so.6 | grep GLIBCXX_3.4.31

g++ --version

pacman -Qi freecad

It turns out that the pkgconf dependency was missing - pkgconf

Camotics now runs and works, but FreeCAD that requires it for some reason swears -

Invalid version: 'camotics: /tmp/.mount_1.AppIQImND0/usr/lib/libstdc++.so.6: version GLIBCXX_3.4.31' not found (required by /usr/lib/libv8_libplatform.so) camotics: /tmp/.mount_1.AppIQImND0/usr/lib/libstdc++.so.6: versionGLIBCXX_3.4.31' not found (required by /usr/lib/libv8.so) camotics: /tmp/.mount_1.AppIQImND0/usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.31' not found (required by /usr/lib/libv8_libbase.so)' Traceback (most recent call last): File "<string>", line 160, in Initialize File "/tmp/.mount_1.AppIQImND0/usr/lib/python3.11/site-packages/packaging/version.py", line 52, in parse return Version(version) ^^^^^^^^^^^^^^^^ File "/tmp/.mount_1.AppIQImND0/usr/lib/python3.11/site-packages/packaging/version.py", line 198, in init raise InvalidVersion(f"Invalid version: '{version}'")

Do we have any way to cheat the FC?
