Increase verbosity / Show compilation flags

[skoudoro]

Hi meson-python Team.

Thank you for this package. is it possible to increase verbosity?

When I do pip install -vvv . I would like to see compilation flags like (clang -Wno-unused-result -Wsign-compare -Wunreachable-code -DNDEBUG -fwrapv -O2 -Wall -fPIC -O2 -isystem /opt/homebrew/Caskroom/miniforge/base/envs/dipy-39-x86/include -fPIC -O2 -isystem /opt/homebrew/Caskroom/miniforge/base/envs/dipy-39-x86/include -I/opt/homebrew/Caskroom/miniforge/base/envs/dipy-39-x86/include/python3.9 -c test.c -o test.o -msse2 -mfpmath=sse )

but currently, it is hidden.

is there a way to do that? if not, should I create an issue ?

Thank you for the feedback!

Yes, there is. Passing -v to pip will cause it to show the meson build output, but that doesn't show compilation flags by default. So in adding you need to use the -v/--verbose option to meson compile. So this will work:

# replace -C by --config-settings= for pip versions older than 23.1
pip install . -v -Ccompile-args=-v
