Erroneous paths in 'gcc --print-search-dirs' #9411

Open lempamo opened 3 years ago

lempamo commented 3 years ago

I was trying to install GTK4 from the repo using meson, but the build failed. After some further investigation, it turns out that the GCC I was using (which came from MSYS) had some library search paths set to the D drive.

Why is this the case, and how can I remove them?

Further details: https://github.com/mesonbuild/meson/issues/9127

Biswa96 commented 3 years ago

Can you provide some more information? It will be easy to reproduce

The erroneous path D:/a/_temp/msys/ came from GitHub Actions CI setup. Other paths look normal.

jeremyd2019 commented 3 years ago

It's just that the build environment paths msys root D:/a/_temp/msys/msys64/ are leaking into the built gcc.

rubyFeedback commented 3 years ago

Interesting. But these paths don't confuse any compile-related aspects?

Failing to compile GTK4 is an issue though. I actually also had problems compiling it via meson; in my case I had missing symbols that somehow could not be found. Since I don't know windows that well I decided to skip it for now and re-try at some later point in the future.

revelator commented 3 years ago

try adding -fcommon to CFLAGS and see if the symbols are still missing ?.

acidtonic commented 3 years ago

This is effecting me in the linked issue above (#9615)

Somehow this path gets built into the code-generator step of gdlmm and fails trying to run m4.exe from that erroneous D-drive path.

pineapplemachine commented 3 years ago

I am also having a related issue. D:/a/_temp/msys/msys64 subdirectories are inexplicably in my gcc search paths, and this is making meson unusable. It is currently not possible to run meson setup because of this issue. Here are some relevant logs:
