MAC development Environment Configuration Related: Installing GCC

From: Mac install GCC

The development toolchain in your Mac is all about Xcode, but it's not necessary to install a Xcode if you just want to use gcc,g++ to compile C + + code. Update: Version 4.3 of Xcode has released the graphical development interface and command-line tools separately. And even if Xcode is installed, the default GCC compiler is LVMM, not the pure GNU gcc. If you want to use pure gcc, the best way is to manually compile one yourself. There are two main methods:

1. Installation via homebrew

This method is relatively simple, if the MAC is already installed homebrew, the specific command:

Brew Tap Homebrew/versions

Brew install [flags] gcc49

where [flags] some need to support the language of eucalyptus, such as –enable-cxx–enable-fortran

2. Github

3. Install by hand

This method can install the latest version of GCC, or any other required version

version=4.8.0

prefix=/usr/gcc-$ (VERSION)

Languages=c,c++,fortran

Make= ' make-j2′# compiled with two cores

Brew-path () {Brew Info $ | head-n3 | tail-n1 | cut-d "-F1;}

# Prerequisites

Brew Install GMP

Brew Install MPFR

Brew Install LIBMPC

# Download & Install the latest GCC

Mkdir-p $PREFIX

mkdir TEMP-GCC

CD TEMP-GCC

wget ftp://ftp.gnu.org/gnu/gcc/gcc-$VERSION/gcc-$VERSION. tar.gz

Tar xfz gcc-$VERSION. tar.gz

RM gcc-$VERSION. tar.gz

CD gcc-$VERSION

mkdir Build

CD Build

.. /configure \

–prefix= $PREFIX \

–with-gmp=$ (brew-path GMP) \

–with-mpfr=$ (Brew-path mpfr) \

–with-mpc=$ (Brew-path libmpc) \

–program-suffix=-$VERSION \

–enable-languages= $LANGUAGES \

–with-system-zlib \

–enable-stage1-checking \

–enable-plugin \

–enable-lto \

–disable-multilib

$MAKE Bootstrap

Make install

# Uncomment for cleanup ...

# CD: /.. /..

# Rm-r TEMP-GCC

When you are finished, you will install GCC in/usr/gcc-4.8.0, and then you can create a soft link to the GCC or add the bin path to the $PAHT variable
