c - 用C编写的SDL程序中的段错误

Question

我正在为 uni 做一个 SDL 项目，并在 Windows 上的 visual studio 中制作了一个完整的工作程序，但是当我将程序放在 Linux 上(演示需要)时，我遇到了段错误。我想知道我的 cmakelist 文件是否错误，因为 gdb 输出主要是 sdl 库中的内容，但我真的不确定，因为我是 cmake 的新手。

我试图使用 gdb 找出段错误，但没有太大帮助!我对 Windows 版本所做的所有更改是我制作了一个 cmakelists.txt 并更改了我的头文件中的 include 以用于 linux 上的 SDL。

GDB 输出:

xcb_disconnect() 无法调用您的 close() 版本。重命名它，使其不与 POSIX 的 close() 名称冲突或将其声明为 static。
