算法库：clapack安装配置

类似于opencv、jpeglib和pnglib的安装配置。

opencv安装配置见：http://www.cnblogs.com/dzyBK/p/4954945.html

jpeglib和pnglib安装配置见：http://www.cnblogs.com/dzyBK/p/4999180.html

clapack官方安装配置见：http://icl.cs.utk.edu/lapack-for-windows/clapack/index.html

官方有两种安装配置方法。这里阐述简单一种，即”Easy Windows Build”。官方阐述如下：

1. Downloadclapack-3.2.1-CMAKE.tgz and unzip.
2. Download cmake and install it on your machine.
3. Open CMAKE

• Point to your CLAPACK-3.2.1-CMAKE folder in the source code folder
• Point to a new folder where you want the build to be (not the same is better)
• Click configure, check the install path if you want to have the libraries and includes in a particular location.
• Choose Visual Studio Solution. You can also choose nmake or any other platform.
• You may have to click again configure until everything becomes white
• Click generate, that will create the Visual Studio for CLAPACK and you are done.
• Close CMAKE

1. Look in your "build" folder, you have your CLAPACK Visual Studio Solution, just open it.
2. Build the "ALL_BUILD" project, it will build the solution and create the librarires
3. Build the "INSTALL". This will put the libraries and include in your install folder.
4. Build the "RUN_TESTS". The BLAS and CLAPACK testings will be run.

这里，我详细阐述一下自己的安装配置的过程。

首先，当然是要下载clapack文件。

下载的版本是：clapack-3.2.1-cmake.gz。

下载地址：http://icl.cs.utk.edu/lapack-for-windows/clapack/clapack-3.2.1-CMAKE.tgz

在C盘下新建目录clapack，然后将下载的clapack-3.2.1-CMAKE.gz文件复制进去，右击并选择“解压到当前文件夹”。在clapack目录下再新建一个目录clapack-3.2.1-BUILD。最终目录结构如下所示。

  

打开ckmake-gui，源码位置：C:/clapack/clapack-3.2.1-Cmake，生成文件选择：C:/clapack/clapack-3.2.1-BUILD。如下图所示。

点击左下角的“configure”，弹出编译器选择项，根据自己的实际情况选择即可。通常按其默认认即可。我安装的是vs2013，所以选择“visual studio 2013”。如下图所示。

单击“Finish”后就开始编译啦。编译结束后，再次或反复单击“configure”，直到背景变成白色。根据需要可选择“USE_BLAS_WARP”。再次反复单击“configure”，直到背景变成白色。

最后单击“generate”，生成结束后就会在C:\clapack\clapack-3.2.1-Build下生成“CLAPACK.sln”，用vs打开。先编译“ALL_BUILD”，再编译“INSTALL”，最后编译“RUN_TESTS”。编译过程中，可能会有些失败，无需要理会。

以上都编译结束后，将会在C:\Program Files (x86)\CLAPACK下生成所需要的头文件和库文件。

接下来就配置工程。

vc++包含目录添加：C:\Program Files (x86)\CLAPACK\include

vc++库目录添加：C:\Program Files (x86)\CLAPACK\lib

链接器->输入->附加依赖项添加：blasd.lib, lapackd.lib, libf2cd.lib
