我想在 mac os 上开发 C++ 程序，我已经安装了带有一堆框架的 Xcode。
但是我想在没有 Xcode IDE 的情况下编写代码，而是编写我自己的 makefile 并直接使用 gcc(Xcode 附带)进行编译/链接。
以一个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
或
gcc -I/usr/include/ -L/usr/lib -framework OpenGL -framework GLUT -lm main.cpp
但是他们以链接错误告终

我错过了什么吗？
最佳答案
使用g++ 编译C++。它是 GCC 的 C++ 前端。例如:
g++ -I/usr/include/ -L/usr/lib -framework OpenGL -framework GLUT -lm main.cpp
