求助如何在MAC里使用gcc和openmp（已经下载了）

Question

用homebrew下载安装了gcc和openmp，但是在xcode里输入
#include <omp.h>
会报错omp.h not found
在终端里输入gcc -v
显示

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 8.0.0 (clang-800.0.38)
Target: x86_64-apple-darwin15.5.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

然后我找出来了安装了的gcc
gcc-6.2.0 already installed
但是想调用gcc又用不了

liuchongdeMacBook-Pro:~ liuchong$ gcc-6.2.0 -o test.out -fopenmp omp.c
-bash: gcc-6.2.0: command not found
liuchongdeMacBook-Pro:~ liuchong$ gcc6.2.0 -o test.out -fopenmp omp.c
-bash: gcc6.2.0: command not found
liuchongdeMacBook-Pro:~ liuchong$ gcc6 -o test.out -fopenmp omp.c
-bash: gcc6: command not found

求助啊，搜遍所有网页，搞了好几天了还是不能用
