Error while compiling Qt6.9.0 on debian 12

[YamiTheWitch]

I set up a fresh debian 12 64bit image in a VM to try building my application for linux but there are no compiled binaries available so i decided to compile it myself.

I installed the dependencies and cmake.

I followed the tutorial at https://doc.qt.io/qt-6/linux-building.html with the sources from git.

I ran the configure command from the qt-build directory as follows:

../qt-sources/configure -init-submodules -submodules qtbase,qttools,qtcharts,qvirtualkeyboard

This finished without any issues. After running cmake --build . --parallel; it crashed with the following after compiling for a while:

Hi,

Set parallel to 1, you should have the exact point of failure.

[YamiTheWitch]

After running the command "cmake --build . parallel 1" it continued and finished building without another error?

@YamiTheWitch said in Error while compiling Qt6.9.0 on debian 12:

building without another error?

c++: fatal error: Killed signal terminated program cc1plus

so it was killed because the machine ran out of memory
