Variable QMAKE_CXX.COMPILER_MACROS is not defined.

OrazioArcidiacono

Hello, I'm creating a docker/container with the following docker file. But when I try to do qmake in a simple project I have this error

root@99782fdb152a:/workspace/simple-qt-project# qmake
/opt/Qt/mkspecs/features/toolchain.prf:76: Variable QMAKE_CXX.COMPILER_MACROS is not defined.
Project ERROR: failed to parse default include paths from compiler output

Can you help me?

Hi,

From the looks of it, in your final stage, you forgot to install the compiler and other tools required to do development.

@SGaist
Can you try to be more precise please?

SGaist

For the last stage you start from bookworm-slim and only copy the Qt build and a log file.
Thus you have a bare bone system with no compiler, no developer helper tools such as make, etc.
