Hey Dennis,

according to the error message, your system is missing the C preprocessor.
This is indeed related to podman, because you are most certainly running a minimal system inside, and thus you need to install the package `cpp` to install the C preprocessor. Clang does not have any dependency on it and thus it is most likely missing.

HTH,
Florian

I tried the solution for this problem but as expected without success. But now I have no ideas anymore, so I would appreciate all kind of help.
