最近我清理安装了 Yosemite 10.10.2

我还使用安装了 gcc

brew install gcc

现在我正在尝试从源代码构建和安装pythonand openmpi，因为以前我遇到过gfortranand的问题clang。

所以我做了

brew install openmpi --build-from-source -verbose 
brew install python --build-from-source -verbose

带有变量和别名：

export CC=gcc-4.9
export CXX=g++-4.9
export CPP=g++-4.9
export LD=gcc-4.9
export FC=gfortran-4.9
export HOMEBREW_CC=gcc-4.9
export HOMEBREW_LD=gcc-4.9
export HOMEBREW_CXX=g++-4.9
export HOMEBREW_CPP=g++-4.9
export HOMEBREW_FC=gfortran
alias cc=gcc-4.9
alias gcc=gcc-4.9
alias c++=c++-4.9
alias g++=g++-4.9

仍然收到以下错误：

Error: pkg-config 0.28 did not build

clang我的理解是和gcc-4.9配置之间存在冲突。

我可以暂时解决它：

brew install pkg-config

因此，它不会从源代码构建并使用 clang 配置。

我看到 Xcode 仍在包含和库路径中，我认为这会阻止与 gcc-4.9 的链接。

如何仅pkg-config使用安装gcc-4.9？

按照此说明更改后问题解决：

typedef void (^dispatch_block_t)(void); // this is for clang

到

typedef void* dispatch_block_t;  //this is for gcc-4.9
