SDL2.0/OpenGL代码赢得'；不编译

我试图在终端中使用gcc编译一个简单的SDL/OpenGL程序。以下是代码（main.c）：

我得到以下错误：

这似乎表明我没有正确地包含SDL2库。然而，我认为这是通过-lSDL2选项处理的。关于这里的错误有什么想法吗？

在linux上，您应该不包含-lSDL2，而是使用

SDL2 config

脚本。它有一些奇怪的依赖项，只有那个脚本才能解决它。您应该使用以下内容进行编译：

gcc -o ./bin/gl_nbody -I/usr/local/include/SDL2 `sdl-config --cflags --libs` -g -lGLEW -lGL -lX11 -Wl,-rpath,/usr/local/lib -L/usr/local/lib ./src/main.c

SDL Wiki上的常见问题解答显示了如何执行此操作的更多详细信息：

可能缺少-lsdl2main libSDL2.a所在目录的-L参数。可能-L/usr/本地/lib@cup你读过所有的gcc命令行了吗？因为它已经在那里了…我的坏问题-在800x600屏幕上工作的问题。您是否尝试过将-L/usr/local/lib放在-lSDL2之前
