如您所见，我将所需的参数传递给了gcc.为什么不起作用? Linux Mint 12.

As you can see, i pass the required parameters to the gcc. Why it does not work? Linux Mint 12.

推荐答案

这确实是一个FAQ(在这里已被多次询问和回答).链接时，参数顺序很重要.图书馆应排在最后(并保持良好状态).您应该运行

It really is a FAQ (and has been asked and answered many times here). Order of arguments matters when linking. Libraries should go last (and in the good order). You should run

gcc -Wall -g light.c -lGL -lGLU -lglut -o light
