2.下載好GSL安裝檔(gsl-1.8-src.exe)，並安裝
http://gnuwin32.sourceforge.net/downlinks/gsl-src.php
3.C:\Program Files\GnuWin32\src\gsl\1.8\gsl-1.8\VC8底下，執行專案:libgsl.sln
4.libgsl要建置四次(右鍵-->建置)，分別為Debug-DLL，Debug-StaticLib，Release-DLL，Release-StaticLib模式下(選擇上方工具列的下拉式選單即可)
5.install_libgsl專案右鍵-->建置，C槽底下就會出現編譯好的檔案，但lib bin是空的
6.修改install_libgsl右鍵中的屬性-->組態屬性-->建置事件-->建置前事件-->命令列，內容為
mkdir %LIBGSL_INSTALL_DIR%\bin
if exist .\..\libgsl\Debug-DLL\libgsl_d.dll copy .\..\libgsl\Debug-DLL\libgsl_d.dll %LIBGSL_INSTALL_DIR%\bin
if exist .\..\libgsl\Release-DLL\libgsl.dll copy .\..\libgsl\Release-DLL\libgsl.dll %LIBGSL_INSTALL_DIR%\bin
if exist .\..\libgslcblas\Debug-DLL\libgslcblas_d.dll copy .\..\libgslcblas\Debug-DLL\libgslcblas_d.dll %LIBGSL_INSTALL_DIR%\bin
if exist .\..\libgslcblas\Release-DLL\libgslcblas.dll copy .\..\libgslcblas\Release-DLL\libgslcblas.dll %LIBGSL_INSTALL_DIR%\bin
mkdir %LIBGSL_INSTALL_DIR%\lib
if exist .\..\libgsl\Debug-StaticLib\libgsl_d.lib copy .\..\libgsl\Debug-StaticLib\libgsl_d.lib %LIBGSL_INSTALL_DIR%\lib
if exist .\..\libgsl\Release-StaticLib\libgsl.lib copy .\..\libgsl\Release-StaticLib\libgsl.lib %LIBGSL_INSTALL_DIR%\lib
if exist .\..\libgslcblas\Debug-StaticLib\libgslcblas_d.lib copy .\..\libgslcblas\Debug-StaticLib\libgslcblas_d.lib %LIBGSL_INSTALL_DIR%\lib

if exist .\..\libgsl\Debug-DLL\libgsl_dll_d.lib copy .\..\libgsl\Debug-DLL\libgsl_dll_d.lib %LIBGSL_INSTALL_DIR%\lib
if exist .\..\libgsl\Release-DLL\libgsl_dll.lib copy .\..\libgsl\Release-DLL\libgsl_dll.lib %LIBGSL_INSTALL_DIR%\lib
if exist .\..\libgslcblas\Debug-DLL\libgslcblas_dll_d.lib copy .\..\libgslcblas\Debug-DLL\libgslcblas_dll_d.lib %LIBGSL_INSTALL_DIR%\lib
if exist .\..\libgslcblas\Release-DLL\libgslcblas_dll.lib copy .\..\libgslcblas\Release-DLL\libgslcblas_dll.lib %LIBGSL_INSTALL_DIR%\lib
7.install_libgsl專案右鍵-->建置，C槽底下就會出現編譯好的lib bin
8.vs2008中，開啟專案empty-->工具-->選項-->專案和方案
可執行檔加入:C:\libgsl-1.8\bin
include檔案加入:C:\libgsl-1.8\include
程式庫檔加入:C:\libgsl-1.8\lib
9.專案右鍵-->屬性-->連結器-->輸入-->其他相依性加入:libgsl_d.lib libgslcblas_d.lib
