Re: [Haskell-cafe] Damn you hmatrix

Could you explain in more details? I've searched through the files (both on the msys folder and OpenBlas folder) but could not find a file called libgfortran/libgfortran-3 ‫בתאריך שבת, 29 ביולי 2017 ב-11:14 מאת <‪bruno@ruomad.net‬‏>:‬

Just rename/copy/link libgfortran-3 to libgfortran I solved the same problem this way

I did not see this guide, but even when I follow the instruction when I try to install hmatrix as in the last step of the guide and get a /missing C library: libgfortran-3. All the actions I described in the first email have resulted in the same results.

Have you seen the instructions here?

Hi cafe, I have a very annoying problem with hmatrix. I have a project which depends on it. I can use `stack build` with no errors but when I try to load it to GHCi(`stack ghci`) I get the following error: sh-4.3$ stack ghci [0mApple-0.1.0.0: configure (lib) [0m [0mConfiguring Apple-0.1.0.0... [0m [0mApple-0.1.0.0: initial-build-steps (lib) [0m [0mConfiguring GHCi with the following packages: Apple [0m GHCi, version 8.0.2: http://www.haskell.org/ghc/ :? for help ghc.EXE: addDLL: libblas.dll (Win32 error 126): The specified module could not be found. ghc.EXE: Could not load `libblas.dll'.

ghc.EXE: unable to load package `hmatrix-0.18.0.0'

This is really bizarre, and could not find something online to help me fix this. I'm using stack 1.5.0 with ghc 8.0.2

On a side note, I've seen some discussions about why the C libraries can't be added automatically but did not understand most of it, if someone can explain it would be highly appreciated.
