如何在Windows下使用BLAS和LAPACK构建hmatrix？ [英] How to build hmatrix with BLAS and LAPACK under Windows?

问题描述

Windows 10 x64
Cabal 1.22

我遵循Windows部分中的步骤 https://github.com/AlbertoRuiz/hmatrix/blob/master/INSTALL.md

我下载了hmatrix资源和gsl-lapack-windows.zip。
当我尝试安装hmatrix时：

\Projects\workspace\hmatrix-0.16.1.5> cabal install
--extra-include-dirs = D：\Projects\workspace\gsl -lapack-windows\ --extra-lib-dirs = d：\Projects\workspace\gsl -lapack-windows \

我得到了这个消息，我仍然无法解决：

配置hmatrix-0.16.1.5 ...无法安装hmatrix-0.16.1.5
生成日志（
D：\Projects\workspace\\ \\ matrix-0.16.1.5.cabal-sandbox \logs\hmatrix-0.16.1.5.log
）：配置hmatrix-0.16.1.5 ...
setup-Simple-Cabal-1.22.4.0 -x86_64-windows-ghc-7.10.2.exe：缺少
依赖于外部库：
*缺少C库：blas，lapack，blas，lapack通常可以通过安装系统软件包来解决此问题提供这些
库（您可能需要-dev版本）。如果库已经安装了

标志--extra-include-dirs =和--extra-lib-dirs =指定$ b $他们是。 cabal：错误：某些软件包安装失败：在配置步骤中
hmatrix-0.16.1.5失败。例外是：
ExitFailure 1

- dev versions我认为只适用于基于* nix的操作系统。在我给cabal的文件夹中有blas.dll和lapack.dll。

可能是什么问题？

解决方案

试试这个：

1. 从 https://sourceforge.net/projects/mingw-w64/files/ ，在我的情况下 x86_64 -posix-SEH ）。我们只需要 libgfortran-3.dll ，它不存在于ghc的mingw中。或者你可以从这里得到它： http://icl.cs.utk.edu/lapack-for-windows/libraries/VisualStudio/3.6.0/Dynamic-MINGW/Win64/libgfortran-3.dll （如果需要，用Win32替换Win64）


2. 从 https://sourceforge.net/projects/openblas/files/ （在我的例子中是 Win64-int32 ）。


3. 在某些文件夹中放置 libopenblas.dll 和 libgfortran-3.dll ，在我的情况下 C：\Programs\lib


4. cabal install hmatrix --flags = openblas --extra-lib-dirs = C ：\Programs\lib

就是这样。你还必须将libs传递给 ghci （所有库都必须在PATH中，所以在我的例子中ghc的 mingw \bin 和 C：\Programs\lib 位于PATH中）：

ghci -llibopenblas -llibgfortran-3 -llibgcc_s_seh-1

其中 libgcc_s_seh-1.dll 是在ghc的mingw（在我的情况下： C：\Programs\ghc\ghc-8.0.1\mingw\bin ）

注意：使用ghc-8.0.1测试

更新：我发现现在可以少做步骤

Windows 10 x64 Cabal 1.22

I'm following steps in Windows section https://github.com/AlbertoRuiz/hmatrix/blob/master/INSTALL.md

I downloaded hmatrix sources and gsl-lapack-windows.zip. When I try to install hmatrix with:

D:\Projects\workspace\hmatrix-0.16.1.5>cabal install --extra-include-dirs=D:\Projects\workspace\gsl-lapack-windows\ --extra-lib-dirs=d:\Projects\workspace\gsl-lapack-windows\

I got this message that I'm still cannot solve:

Configuring hmatrix-0.16.1.5... Failed to install hmatrix-0.16.1.5 Build log ( D:\Projects\workspace\hmatrix-0.16.1.5.cabal-sandbox\logs\hmatrix-0.16.1.5.log ): Configuring hmatrix-0.16.1.5... setup-Simple-Cabal-1.22.4.0-x86_64-windows-ghc-7.10.2.exe: Missing dependencies on foreign libraries: * Missing C libraries: blas, lapack, blas, lapack This problem can usually be solved by installing the system packages that provide these libraries (you may need the "-dev" versions). If the libraries are already installed but in a non-standard location then you can use the flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are. cabal: Error: some packages failed to install: hmatrix-0.16.1.5 failed during the configure step. The exception was: ExitFailure 1

"-dev versions" I think is only for *nix based OSes. In folders I give to cabal there are blas.dll and lapack.dll.

What could be the problem?

解决方案

Try this:

1. Install mingw from https://sourceforge.net/projects/mingw-w64/files/, in my case x86_64-posix-seh). We need just libgfortran-3.dll, which is not present in ghc's mingw. Or you can get it from here: http://icl.cs.utk.edu/lapack-for-windows/libraries/VisualStudio/3.6.0/Dynamic-MINGW/Win64/libgfortran-3.dll (Replace Win64 with Win32 in url if necessary)
2. Get OpenBLAS binaries from https://sourceforge.net/projects/openblas/files/ (in my case Win64-int32).
3. Place libopenblas.dll and libgfortran-3.dll in some folder, in my case C:\Programs\lib
4. cabal install hmatrix --flags=openblas --extra-lib-dirs=C:\Programs\lib

That's all. You also have to pass libs to ghci (all libs must be in PATH, so in my case ghc's mingw\bin and C:\Programs\lib are in PATH):

ghci -llibopenblas -llibgfortran-3 -llibgcc_s_seh-1

where libgcc_s_seh-1.dll is in ghc's mingw (in my case: C:\Programs\ghc\ghc-8.0.1\mingw\bin)

NOTE: tested with ghc-8.0.1
UPDATE: i've found that now it can be done in less steps
