Mingw pkg-config not working
Thu Feb 27 16:20:00 GMT 2020
I wanted to say that I modified the script in this way and it seems
that it has resolved all issues:
if [ "$#" -eq 1 ] && [ "$1" == "--version" ]; then
exec pkgconf --version
exec pkgconf --personality=i686-w64-mingw32 $@
Fixing x64_64 is easy, I have just replaced i686-w64-mingw32 with
x86_64-w64-mingw32 in the personality.
I hope you will find this fix useful and, if you think it is good, the
maintainer of the package could rewrite those scripts in the same way.
