codeblocks - 如何将 sdl2 与 CoDeBlocks 一起使用

Question

我很难用 Code::Blocks 设置 SDL2
我尝试了一些在谷歌上找到的教程，我也尝试通过在这个网站上搜索来解决问题，但是我没有解决它，每次我在编译一个简单的程序时遇到错误
所以我希望有人好心给我一个简单的分步指南来帮助我
首先让我知道 code::blocks 和 sdl 2 是否一起工作？

那么我不得不说，我使用的是带有 Windows 7 - 64 BITS 的 HP 可移植计算机
我得到了 Code::Blocks 12.11，上面安装了嵌入式 Mingw32 4.7.1
我想我在我的设置中正确链接了库和包含文件，但仍然没有工作，我即将放弃

Answer 1

下载 SDL2-devel-2.0.1-mingw.tar.gz

从 SDL2-2.0.1\i686-w64-mingw32 解压这些目录:\bin、\include、\lib 和\share 到例如X:\CodeBlocks\MinGW\

创建目录 %APPDATA%\CodeBlocks\UserTemplates\SDL2 并粘贴文件 SDL2.cbp、main.cpp 和 cb.bmp

SDL2.cbp:

注意:根据需要编辑驱动器号和路径 X:\CodeBlocks
