一个图形界面的编译？紧急求助。(在线等)

blueprint

我想编译下面这个showmesh。c，它是一个图形显示程序，要用到图形的库程序，我不知道怎么弄，大家帮帮忙。谢谢。

On some machines you should specify the path to the X libraries and include files. This is achieved with the -I and -L options. For example, when I compile ShowMesh on the Red Hat Linux, I have to type:
gcc -o ShowMesh -O3 -I/xxx -L/xxx showmesh.c -lX11
