我已经google了它的地狱,似乎没有办法在OS X上安装gcc而不安装Xcode(占用1.5GB的空间).我只需要gcc,而不是Xcode附带的其他垃圾.在这一点上,我将采取任何其他类型的C编译器.
我知道我可以简单地安装Xcode,但这不是重点,因为我既没有原始安装光盘也没有快速的互联网连接.
那么......有没有人有任何建议？
编辑:对不起,如果我不清楚,但我也需要标题.我目前正在通过fink安装gcc4,它也在下载共享库.我会更新进度.
编辑2:好的,所以我用fink成功安装了gcc.但是,它几乎没用:"错误:C编译器无法创建可执行文件".谷歌搜索后,我发现没有安装Apple的开发者工具是导致错误的原因.可能是因为我需要所有只能通过Xcode获得的库,标题等.

我不再能够构建使用OpenMP的(简单)并行代码.
通过在这里和那里看,我明白Apple不再使用'gcc'而是'llvm' - 很可能是由于与许可相关的问题.不幸的是'llvm'不支持OpenMP.
我不敢相信很多基于OpenMP的程序在OS X上不再运行,所以我的问题是:如何在Mountain Lion中启用OpenMP？
在阅读了Hristo Iliev的优秀答案之后,我想我失去了比我最初想象的更多.
我没有使用XCode.该建筑基于CMake和make/gcc.昨天我通过macports安装了gcc 4.2,但是 - 截至今天 - 我的代码仍然是源代码形式,因为 - 由于一些奇怪的原因 - 我无法将编译切换到gcc(与OpenMP相关的相同错误).
现在的问题是CMake继续使用llvm编译器.在根CMakeLists.txt中,我添加了以下两行:
set(CMAKE_C_COMPILER "/opt/local/bin/gcc-apple-4.2")
set(CMAKE_CXX_COMPILER "/opt/local/bin/gcc-apple-4.2")
我还添加了两个环境变量:
export CXX=/opt/local/bin/gcc-apple-4.2
export CC=/opt/local/bin/gcc-apple-4.2
当CMake尝试查找OpenMP(FIND_PACKAGE(OpenMP))时,我得到以下输出:
-- The compiler is /opt/local/bin/gcc-apple-4.2
-- Try OpenMP C flag = [-fopenmp]
-- Performing Test OpenMP_FLAG_DETECTED
-- Performing Test OpenMP_FLAG_DETECTED - Failed
