HomeBrew—Mac的利器

上一个Blog说过brew，本来是打算用来装git的，但是在安装GitHub for Mac时有一个过程可以顺便安装git，于是又来尝试gcc了，你说为啥Mac没有自带gcc呢？

Max@UltimateMac:~$ brew install gccError: No available formula for gccGCC is now maintained in homebrew-versions, with major versionnumber in formula name as suffix. Please tap using:    brew tap homebrew/versionsand then install GCC based on its version, e.g., 'brew install gcc47'.

2.发现brew的一个强大的功能，brew tap ——相当于pull GitHub的Repository，而且在pull的过程中可以指定branch。这是一个很酷的功能。

Max@UltimateMac:~$ brew tap homebrew/versionsCloning into '/usr/local/Library/Taps/homebrew-versions'...remote: Reusing existing pack: 1578, done.remote: Counting objects: 3, done.remote: Compressing objects: 100% (3/3), done.remote: Total 1581 (delta 0), reused 2 (delta 0)Receiving objects: 100% (1581/1581), 515.07 KiB | 9.00 KiB/s, done.Resolving deltas: 100% (814/814), done.Checking connectivity... doneTapped 127 formula

3.然后看一下安装哪个版本的gcc吧。

Max@UltimateMac:~$ brew search gccapple-gcc42   gcc44    gcc46  gcc48llvm-gcc28gcc43      gcc45    gcc47  gcc49If you meant "gcc" precisely:GCC is now maintained in homebrew-versions, with major versionnumber in formula name as suffix. Please tap using:    brew tap homebrew/versionsand then install GCC based on its version, e.g., 'brew install gcc47'.homebrew/dupes/apple-gcc42

4.既然最新的是gcc49，那就：

Max@UltimateMac:~$ brew install gcc49
