c - C 语言编写的 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中制作了一个完全工作的程序，但是当我将该程序放在Linux上(演示所需)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。

我尝试使用 gdb 来追踪段错误，但没有多大帮助!我对 Windows 版本所做的所有更改是我制作了 cmakelists.txt 并更改了 Linux 上 SDL 的头文件中的包含内容。

GDB 输出:

xcb_disconnect() 没有必要调用您的 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。
