Visual Studio 2008中使用科学计算库GSL

http://ixpress.spaces.live.com/blog/cns!8BCB40263F366272!683.entry

1. 下载最新版GSL

@ http://gnuwin32.sourceforge.net/packages/gsl.htm 最新的好像是1.9，不过这里只有1.8，估计1.9还在测试，不过无所谓。

需要下载的是前两个文件：Complete package, except sources和Sources。然后安装。

2. 配置VS和GSL

在VS的菜单tools->options->project and solutions->VC++ directiories里面设置include,bin,lib,sources的文件夹，分别对应gsl的安装目录。include就到gsl的 include就行了，不要到include/gsl下面

然后打开GSL的src文件夹，下面有个VC8文件夹，打开里面的libgsl.sln工程文件并编译（把四种库，debug release 静态 动态全编译了）。然后打开输出文件夹，把lib文件拷到gsl根目录的lib，把dll拷到system32

3. 写程序

工程向导win32 控制台程序。生成之后在工程配置里面找到C/C++ Generation下面的Runtime Libary，改成/MT或者/MTD。

链接gsl的库有两种，静态的和动态的

静态要加入libgsl.lib 和 libgslcblas.lib (release) 或者 libgsl_d.lib 和 libgslcblas_d.lib(debug)

动态dll要加入libgsl_dll.lib 和 libgslcblas_dll.lib (release) 或者 libgsl_dll_d.lib 和 libgslcblas_dll_d.lib(debug)，此外还要写上#define GSL_DLL

加库可以这样

#pragma comment(lib,"libgsl.lib")
#pragma comment(lib, "libgslcblas.lib")

4. 其他

然后就欧了。不过在MFC里面好像编译不了静态链接模式的程序，应该是那个/MT冲突之类的，我不知道。实在不行用dll么。

不过这个gsl就不能出个面向对象的么，看见指针数组就烦。

BUILD GSL LIBRARIES FOR Visual studio
1. Launch Visual C++ Studio
2. Open project C:/Program Files/GnuWin32/src/gsl/1.8/gsl-1.8/VC8/libgsl.sln (assuming default path - replace if it is a different location)
3. Do a build all
4.Verify that after build is complete, new files are generated in subfolders in C:/Program Files/GnuWin32/src/gsl/1.8/gsl-1.8/VC8/libgsl

CONFIGURE PATH SETTINGS IN VISUAL C++ STUDIO
1.Launch Visual C++ studio
2.Select Tools->Options Menu
3.On the tree display in the Options dialog box, select branch for Projects and solutions->VC++ directories
4.On the right side of the dialog, select Executable files in the "show directories for" combo box and add the following paths:
C:/Program Files/GnuWin32/src/gsl/1.8/gsl-1.8/VC8/libgslcblas/Debug-DLL
C:/Program Files/GnuWin32/src/gsl/1.8/gsl-1.8/VC8/libgsl/Debug-DLL

5.In the "show directories for" combo box select "Include files" and add the following path:
C:/Program Files/GnuWin32/include

6.In the "show directories for" combo box select "Library files" and add the following paths:
C:/Program Files/GnuWin32/src/gsl/1.8/gsl-1.8/VC8/libgsl/Debug-DLL
C:/Program Files/GnuWin32/src/gsl/1.8/gsl-1.8/VC8/libgslcblas/Debug-DLL

HOW DO I USE GSL LIBRARY IN MY VC++ PROJECT?
1.Launch Visual studio
2.Open your VC++ project.
3.select menu Project -> properties
4.In the property pages dialog, select tree item "configration properties->Linker->Input
5.On the right hand side details, choose the field "Additional Dependencies" and append the following entries by clicking the ... button:
libgsl_dll_d.lib
libgslcblas_dll_d.lib
