I am trying to install the Ruby gem github-linguist. I am on a Windows machine, and I have tried executing gem install github-linguist via the Msys2, Mingw64, and the regular Windows command shell. I get the same output every time:
Building native extensions. This could take a while...
ERROR: Error installing github-linguist:

The problem appears to be an issue with the -licui18n library, so I tried installing that package with pacman -S mingw-w64-x86_64-icu in the Msys2 shell, and it works perfectly with no errors. But then when I run gem install github-linguist again it still doesn't work. I'm not sure what the error message means by "you must install development tools first", that's not very specific.
I'm not very familiar with Makefile, so the error message may be more intelligible to someone who has more experience with it.
Solved! I needed to point the installer to where the icu lib files were. I had installed the package multiple times in my various attempts to solve the problem, and therefore had installed the .dll files to both the /mingw64/lib/ and /usr/lib/ directories. I ran the following command in the Mingw64 shell: find /usr -name 'libicu*' and saw this:
/usr/lib/libicudata75.dll.a
/usr/lib/libicui18n.dll.a
/usr/lib/libicui18n75.dll.a
/usr/lib/libicuio.dll.a
/usr/lib/libicuio75.dll.a
/usr/lib/libicutest.dll.a
/usr/lib/libicutest75.dll.a
/usr/lib/libicutu.dll.a
/usr/lib/libicutu75.dll.a
/usr/lib/libicuuc.dll.a
/usr/lib/libicuuc75.dll.a
/usr/lib/w32api/libicu.a
Notice the presence of the libicui18n.dll.a file. That is the one the installer needed. Then I ran gem install github-linguist -- --with-icu-lib=/usr/lib and it worked!
