堆栈无法找到libgfortran-3.can当尝试使用hmatrix构建时

Question

我正在尝试用GHC 8.0.2在我的Windows 10计算机上安装hmatrix。我一直在跟踪答案这里，但是当我试图构建它时，它说它找不到libgfortran-3.dll，尽管我确信我将它添加到BLAS目录中的bin文件夹中。我的代码在这里中，我运行stack build，这就是我得到的：

    Cabal-simple_Z6RU0evB_1.24.2.0_ghc-8.0.2.exe: Missing dependency on a foreign
    library:
    * Missing C library: libgfortran-3
    This problem can usually be solved by installing the system package that
    provides this library (you may need the "-dev" version). If the library is
    already installed but in a non-standard location then you can use the flags
    --extra-include-dirs= and --extra-lib-dirs= to specify where it is.

D:\OpenBLAS-v0.2.19-Win64-int32\bin同时包含libopenblas.dll和libgfortran-3.dll，并且blas目录是从这个url获取的。

谢谢你的帮助

我已经按如下方式安装了它。

在yourpath\to\stack\x86_64-windows\msys2-20150512中，通过双击msys2_shell.bat打开msys2外壳.

在外壳中，键入：

pacman -S mingw-w64-x86_64-toolchain

然后在stack.yaml中添加这些“额外”

extra-include-dirs:
- yourpath\to\OpenBLAS\include
extra-lib-dirs:
- yourpath\to\OpenBLAS\lib
- yourpath\to\stack\x86_64-windows\msys2-20150512\usr\lib\gcc\x86_64-pc-msys\6.3.0
- yourpath\to\stack\x86_64-windows\msys2-20150512\mingw64\bin
