Note: there are more failed tests, but they seem unrelated so I will post them in separate issues.

[hakonhagland]

This seems to be related to this issue. For example

> PKG_CONFIG_PATH=corpus/lib/pkgconfig pkg-config --libs foo
-L/test/lib -lfoo -lbar -lbaz

whereas it should give output -L/test/lib -lfoo

[plicease]

This seems to be a bug in msys version of pkg-config. I wonder if pkgconf is better behaved?

[hakonhagland]

Apparently pkgconf is not available on my system:

> pkgconf
bash: pkgconf: command not found

[plicease]

I think it can be installed with pacman

[hakonhagland]

This does not work:

$ pacman -S pkgconf
error: target not found: pkgconf

[plicease]

I'm closing this as I believe this to be a bug in pkg-config.

[hakonhagland]

I just found that they have recently switched from pkg-config to pkgconf, see this pull request. So I updated my MSYS2 installation, and now pkg-config works correctly!

Also after applying the patch in PR #246, all tests for Alien-Build on MSYS2 now passes here!
