【SDL的編程】VC環境搭建

編輯：關於C語言

SDLsimple DirectMedia Layer）是一個可跨平台的開源庫，最近由於自己的興趣，就把它windosXP下的環境搭建了下。 PC：Mircrosoft Windows XP Service Pack3 Platform：Mircrosoft Visual C++ 6.0 SourceCode：SDL-devel-1.2.14-VC6.zip

步驟 1. 解壓SDL-devel-1.2.14-VC6.zip.將解壓後的lib文件夾裡把SDL.lib SDLmain.lib拷貝到VC6.0安裝目錄的lib文件夾下面。 2. 將SDL.dll拷貝到系統盤的WINDOWS/SYSTEM32目錄下如果你要將之後生成的SDL應用程序轉移到其他沒有配置SDL環境的機器上用的話，請將SDL.dll一起拷貝）。 3. 在VC6.0安裝目錄的include文件夾下面新建一個SDL的目錄，並將SDL-devel-1.2.14-VC6.zip解壓後的include裡的文件拷貝到這個SDL目錄下面。 4. 打開VC6,新建一個project->win32 Application.打開project目錄下面的那個setting，選中C/C++，Category裡選中Code Generation，Use run-time library使用Multithread DLL. 5. 繼續在上面的setting中選中Link，Category裡選中input，在Object/library modules中填入SDL.lib SDLmain.lib 6. 在VC項目中新建一個cpp，並添加到項目中，編譯，運行.
