Debug build (CMAKE) on Linux failing
-
I tried to debug my code using VS2026 remote debug just now, and the build failed:

Hi David,
AutoMoc isn’t failing because of DeepSkyStacker or Qt. It’s failing because this file is missing on the Linux machine:
/usr/share/cmake-4.3/Modules/CMakeCXXCompilerABI.cpp
CMake needs that file while creating moc_predefs.h. Your install of CMake 4.3 looks incomplete.
On Linux, try:
ls /usr/share/cmake-4.3/Modules/CMakeCXXCompilerABI.cpp
Reinstall CMake (or use another complete CMake version)
Delete the build folder (~/.vs/DSS/build) and rebuild
That should clear this error.Thanks,
Ansif
