在没有Xcode IDE的情况下开发C.

我想在mac os上开发C程序,我已经安装了 Xcode和一堆框架.

但是我想编写没有Xcode IDE的代码,只需编写我自己的makefile并直接编译/链接gcc(随Xcode一起提供).

以opengl程序为例.我试着用命令编译它：

gcc -I/usr/include/
-I/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/GLUT.framework/Headers/
-I/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/OpenGL.framework/Headers
-L/usr/lib -L/usr/X11/lib/ -L/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/OpenGL.framework/Libraries/
-lGL -lGLU -lGLUTt main.cpp

要么

gcc -I/usr/include/ -L/usr/lib
-framework OpenGL -framework GLUT -lm main.cpp

但他们最终导致链接错误

我错过了什么？

用g编译C.这是GCC的C前端.例如.：

g++ -I/usr/include/ -L/usr/lib -framework OpenGL -framework GLUT -lm main.cpp
