如何在Windows上安装LAPACK for MSVS 2010？ [英] How to install LAPACK for MSVS 2010 on windows?

问题描述

我正在使用ITPP库（IT ++库）进行我的一个项目。为了使用这个库的eigen_sym（）函数，它要求安装LAPACK。我试过Windows的直接预构建库，但仍然得到的错误。最后在以下网站上：

http://icl.cs.utk.edu/lapack-for-windows/lapack/#libraries

我发现了一个解决方案在构建说明以创建LAPACK和LAPACKE 3.5.0 dll与Windows的MinGW可能工作。

我的cmake build目标是 E：/ LAPACK

输入以下命令时，在cmd提示符下输入错误：

  cd E：/ LAPACK 3.5.0>输入
 C：/MinGW/bin/mingw32-make.exe>输入
  

我得到

  mingw32-make.exe>未找到指定的目标和找不到make文件。停止。 
  

有人可以详细解释步骤6以及告诉我在哪里出问题？
我终于想得到 .dll 和 .lib 文件。

$ b $我可以使用mingw和几乎是从LAPACK页面的构建指南构建LAPACK 3.5 for windows。使用以下步骤

1. 从这里下载lapack.tgz http://netlib.org/lapack/lapack.tgz


2. 解压缩到文件夹。我使用7zip文件管理器解压缩到x：/ Other / test


3. 安装mingw32。我使用这个： http://www.mingw.org/download/installer ，我选择了已安装 mingw32-development-toolkit + mingw32-base + mingw32-gfortran + mingw32-gcc-g ++ strong> msys-base


4. 打开命令提示符



5. 将mingw附加到您的路径

   
   
   

   path = C：/ Mingw / bin;％PATH％
   
   

6. 将目录切换到您提取的位置lapack：对我来说这是X：\Other \ Test\lapack-3.5.0所以我键入的命令是以下（你的路径将是不同的）：
   
   
   

   C：\Users\jdrescher> x：
   
   X：> cd Other\Test\lapack-3.5.0
   
   X：\Other\Test\lapack-3.5.0>
   < Li>为您的构建创建一个文件夹。我使用build

   
   
   

   X：\Other\Test\lapack-3.5.0> mkdir build
   

7. ，然后将目录更改为构建文件夹
   
   
   

   X：\Other\Test\lapack-3.5.0> cd build
   
   X：\Other\Test\ lapack-3.5.0 \build>
   

8. 现在使用CMake配置
   
   
   

   X：\Other\Test\lapack-3.5.0 \build> cmake -GMinGW Makefiles-D BUILD_SHARED_LIBS = ON -D CMAKE_GNUtoMS = ON ..
   

9. 现在使用gnu make构建LAPACK
   
   
   
   

   X：\Other\Test\lapack-3.5.0\build> c：\MinGW\bin\mingw32-make.exe

   
   
   

   注意：此步骤需要几分钟。

步骤完成100％没有错误，我有以下dll在build \bin文件夹： libblas.dll ， liblapack.dll ， libtmglib.dll

还有以下库和exp文件在build \lib文件夹中： libblas.exp ， libblas。 lib ， liblapack.exp ， liblapack.lib ， libtmglib.exp 和 libtmglib.lib 。

I am using the ITPP library (IT++ library) for one of my projects. For using the eigen_sym() function of this library, it asks for installing the LAPACK. I tried the direct prebuilt libraries for Windows but still get the error. Finally on the following site:

http://icl.cs.utk.edu/lapack-for-windows/lapack/#libraries

I found a solution under "Build Instructions to create LAPACK and LAPACKE 3.5.0 dlls for Windows with MinGW" that might work. I did steps 1 to 5 but got stuck 6 onwards.

My destination of the cmake build is E:/LAPACK

I got an error while in the cmd prompt while entering:

cd E:/LAPACK 3.5.0 >Enter
C:/MinGW/bin/mingw32-make.exe >Enter

i'm getting

mingw32-make.exe> No targets specified and no make file found. Stop.

Can someone explain the step 6 onwards in detail and tell me where i'm going wrong? I finally want to get the .dll and .lib files.

解决方案

I was able to build LAPACK 3.5 for windows using mingw and pretty much the build guide from the LAPACK page. Using the following steps

1. Download lapack.tgz from here http://netlib.org/lapack/lapack.tgz
2. Extract to a folder. I used 7zip file manager to extract the tarball to x:/Other/test
3. Install mingw32. I used this: http://www.mingw.org/download/installer and I selected and installed mingw32-developer-toolkit + mingw32-base + mingw32-gfortran + mingw32-gcc-g++ + msys-base
4. Open a command prompt

5. Append mingw to your path

   path=C:/Mingw/bin;%PATH%
   

6. change directory to the location you extracted lapack: For me this was X:\Other\Test\lapack-3.5.0 so the command I typed was the following (your path will be different):

   C:\Users\jdrescher>x:
   X:>cd Other\Test\lapack-3.5.0
   X:\Other\Test\lapack-3.5.0>

7. make a folder for your build. I used build

   X:\Other\Test\lapack-3.5.0>mkdir build

8. then change directory to the build folder

   X:\Other\Test\lapack-3.5.0>cd build
   X:\Other\Test\lapack-3.5.0\build>

9. Now configure with CMake

   X:\Other\Test\lapack-3.5.0\build>cmake -G "MinGW Makefiles" -D BUILD_SHARED_LIBS=ON -D CMAKE_GNUtoMS=ON ..

10. Now use gnu make to build LAPACK
    

    X:\Other\Test\lapack-3.5.0\build>c:\MinGW\bin\mingw32-make.exe

    Note: This step will take several minutes.

After the above steps completed 100% with no errors, I have the following dlls in the build\bin folder: libblas.dll, liblapack.dll, libtmglib.dll

Also the following libraries, and exp files in the build\lib folder: libblas.exp, libblas.lib, liblapack.exp, liblapack.lib, libtmglib.exp and libtmglib.lib.
