C编译错误（无此文件或目录，编译终止）

Question

I'm on Windows trying to learn some OpenGL. I Installed mingw and have a test file. I put my test.c file in a glut folder, which contains glut files such as the glut32.dll and library file. I used mingw in cmd to run the file using this:

gcc opengl.c -o opengl -lGL -lGLU -lglut

And I got this error:

opengl.c:1:23 fatal error: GLUT/glut.h: No such file or directory
#include <GLUT/glut.h>

compilation terminated.

Not sure what I'm doing wrong, anybody know? Thanks!

Answer 1

First of all you need to check that there is a glut.h file, in a GLUT folder.

Then you tell the compiler where to find it using the -I command-line option (note, it's capital i , not 1 or l ):

$ gcc -I/path/to/folder opengl.c -o opengl -lGL -lGLU -lglut

In the command above, replace /path/to/folder to the folder where the GLUT folder is.

You might also need to tell the linker where the libraries are, which is done with the -L option:

$ gcc -I/path/to/folder opengl.c -o opengl -L/path/to/libs -lGL -lGLU -lglut

用户定义的头文件语法为#include“ file.h的名称” .......不存在“ <”或“>” ....，因为只是要求编译器检查其目录中是否所有头文件都是存储的... wereas“”让编译器检查当前目录。...当然，请确保标头与ur main.c在同一目录中定义
