我已经下载了 armadillo 6.5。它需要 superLU(4.3) 库来求解稀疏矩阵方程组。

我已经从here 下载了superlu但是当我想在 Windows 中制作它时，它给出了:

( cd SRC; make )
process_begin: CreateProcess(NULL, ( cd SRC; make ), ...) failed.
make (e=2): The system cannot find the file specified.
Makefile:36: recipe for target 'superlulib' failed
make: *** [superlulib] Error 2

如果我手动 cd 到 SRC 目录并在其中执行 make，则会创建很多 *.o 文件，但我又得到了这个错误:

我几乎没有使用“make”和“superlu”的经验。我怎样才能在 Windows 中制作 superlu？是否有适用于 Windows 的预编译 superlu 库？

最佳答案

嗯，看来makefile是为linux系统写的。 我可以做三件事:

1. 按照 superLU FAQ page 上的说明进行操作:

This was tested in MS Visual Studio. However the configuration highly depends on which compiler you using. Normally there is an IDE (Integrated Development Environment) editor associated with your compiler. You can do it in two steps:

Step I: Create SuperLU library file Create a new project, then include all the .c and .h files in SRC directory (they can be put in two folders of the IDE). Change the property of the project to make the output as Library file .lib (not .exe or .dll file). Compile the project to produce the library file, e.g. superlu.lib. (after you successfully compile it, you can build a release version without the debug information).

Step II: Build your own application Create a new project with your own source files which call the SuperLU routines.Add the SRC directory and the directory where superlu.lib is located to the include path and library searching path respectively. Add superlu.lib as the link optional library. Compile your own .dll or .exe file. Then you are done.

If you are using a compiler with command line only, you have to play with the makefile or -I -L -O -c options. As SuperLU calls BLAS routines but BLAS is not a native library of MS Visual Studio, you have to build your own BLAS library in the similar way as SuperLU library. The SuperLU distribution includes a C version of BLAS in SuperLU/CBLAS directory. This version is only functional but not fast. For speed, it's better to use vendor-supplied BLAS (e.g., Intel MKL) or public domain versions (e.g., ATLAS, or Goto BLAS).

我做不对。

1. 为windows重写整个makefile(我也做不到，因为我不知道怎么写makefile)

最后可行的解决方案(对我而言):

1. 我在 github 中找到了一个 repo，它添加了对 windows 的 superLU 构建支持! 你可以找到它here

它有一个 Visual Studio(2010) 解决方案文件，用于构建库并提供一个 lib 文件。

关于c++ - 如何在Windows中制作superlu，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35795372/
