              required but it could not be found.

My command is this.

              stack --extra-lib-dirs=D:/CS294/gsl-1.8-bin/bin build hmatrix-tests

I am using gsl and point lib dir to its bin. Everything else is installed by Stack.

But even if I use gsl-lapack-windows like this I see the same error.

I think you need to install mingw-w64-gsl as explained here: https://github.com/Alexpux/MINGW-packages

@mohanr Has your problem been solved? I am triaging issues and I would like to close this if it is no longer an issue for you.

@mohanr please reopen if this is still a problem.

In fact, to work I had to run stack exec -- pacman -S mingw-w64-x86_64-gsl though now it says it can't find gsl-0 (maybe editting hmatrix-gsl.cabal and changing the gsl-0 reference to gsl will work...)
