过剩已经安装,仍然没有编译

glut already installed, still not compiling

我正在使用以下命令编译程序:

g++ main.cpp -o run -lglut -lm

并出现以下错误:

main.cpp:20:21: fatal error: GL\glut.h: No such file or directory
 #include <GL\glut.h>
                     ^
compilation terminated.

虽然已经安装了 glut:apt-get install freeglut3 freeglut3-dev

反斜杠“\”不是 linux 上的有效路径分隔符。您必须使用斜杠“/”。请注意,windows 也支持该表示法,因此它可以跨平台工作。
