Homebrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

添加PATH

export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
PATH=/usr/local/bin:$PATH

之后安装的程序都在/usr/local/bin里，包括各版本的python等

gcc                 gcc@5               gcc@7               i386-elf-gcc
[email protected] ✔           gcc@6               gcc@8
~/soft/gcc $ 

安装软件包

brew install [email protected]

安装之后

~/soft/gcc $ gcc
gcc             gcc-ar-4.9      gcc-ranlib-4.9  
gcc-4.9         gcc-nm-4.9    
~/soft/gcc $ gcc-4.9 --version

需要建立索引，把系统默认的gcc提成gcc-4.9

gcc默认也安装了gfortran，👍

查询如何使用软件包

~ $ brew info [email protected]
[email protected]: stable 2.4.6 (bottled) [keg-only]
Powerful, clean, object-oriented scripting language
https://www.ruby-lang.org/
/usr/local/Cellar/[email protected]/2.4.6 (13,890 files, 33MB)
  Poured from bottle on 2019-06-09 at 19:10:17
From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/[email protected]
==> Dependencies
Build: pkg-config ✘
Required: libyaml ✔, openssl ✔, readline ✔
==> Caveats
By default, binaries installed by gem will be placed into:
  /usr/local/lib/ruby/gems/2.4.0/bin

You may want to add this to your PATH.

[email protected] is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have [email protected] first in your PATH run:
  echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.bash_profile

For compilers to find [email protected] you may need to set:
  export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
  export CPPFLAGS="-I/usr/local/opt/[email protected]/include"
