Installing Math::GSL on Windows 10, MSYS2

[hakonhagland]

I am trying to install Math::GSL on Windows 10 using MSYS2. Currently I have been able to install the GSL library using Alien::GSL, but when I run perl Build.PL for Math::GSL:

$ perl Build.PL
Checking for GSL using gsl-config
Can't exec "gsl-config": No such file or directory at Build.PL line 296.

***
*** Can't find GSL with gsl-config.
*** Trying with PkgConfig.

Asking PkgConfig with ENV{PKG_CONFIG_PATH}=/usr/lib/pkgconfig:/usr/share/pkgconfig:/lib/pkgconfig:/usr/pkgconfig:/usr/lib/pkgconfig:/usr/local/lib/pkgconfig:/usr/local/pkgconfig:/usr/libdata/pkgconfig:/usr/local/libdata/pkgconfig:/opt/pkgconfig


***
*** PkgConfig failed with error message: Can't find gsl.pc in any of /usr/lib/pkgconfig /usr/share/pkgconfig /lib/pkgconfig /usr/lib/pkgconfig /usr/share/pkgconfig
use the PKG_CONFIG_PATH environment variable, or
specify extra search paths via 'search_paths'

*** Probably you need to install GSL?
***  On Debian/Ubuntu you can use:
***      sudo apt-get install libgsl0-dev
***  On Mac you can use homebrew (http://brew.sh/):
***      brew install gsl
***  On Fedora/CentOS/RedHat/openSUSE you can use
***      sudo yum install gsl-devel
*** Or get GSL at http://www.gnu.org/software/gsl

I believe this is the same problem as #212 which was fixed in PR #213 (but unfortunately did not make it into version 0.42). I will test with the code in PR #213 and see if it works or what more needs to be added for it to work on MSYS2. If we get it to work we might consider releasing a new version 0.43 to CPAN ..

Yes using the fix in #213 worked:

$ perl Build.PL

Have a great day!

But now I get other errors when trying to compile the C files.. I am opening a new issue for that, see #220
