本文档详细介绍了如何在OS X Lion 10.8.4上搭建C++11开发环境。通过下载并编译GCC 4.8.1，解决依赖问题，以及正确配置环境变量，最终成功构建GCC编译器。过程中提到了避免使用非标准路径安装依赖库以防止动态链接问题，并给出了编译GCC的正确步骤，包括使用./contrib/download_prerequisites脚本简化依赖下载和构建过程。

1 下载最新支持C++11的GCC编译器

http://gcc.gnu.org/

http://gcc.gnu.org/gcc-4.8/（下载gcc 4.8.1）

GCC 4.8.1 will be C++11 feature-complete [2013-04-01] Support for C++11 ref-qualifiers was added to the GCC 4.8 branch, making G++ the first C++ compiler to implement all the major language features of the C++11 standard. This functionality will be available in GCC 4.8.1. （注意并不是所有的新特性都支持）

2 编译遇到的问题

首先查看INSTALL说明：file:///Users/gerryyang/code/public/gcc-4.8.1/INSTALL/index.html，然后尝试编译：

sh-3.2#pwd

/Users/gerryyang/code/public/gcc-4.8.1

sh-3.2# ./configure --prefix=/usr/local/gcc-4.8.1/

configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+.
Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify
their locations.  Source code for these libraries can be found at
their respective hosting sites as well as at
ftp://gcc.gnu.org/pub/gcc/infrastructure/.  See also
http://gcc.gnu.org/install/prerequisites.html for additional info.  If
you obtained GMP, MPFR and/or MPC from a vendor distribution package,
make sure that you have installed both the libraries and the header
files.  They may be located in separate packages.

OK，根据错误提示“configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+.”下载依赖的packages，ftp路径也已提示我们“ ftp://gcc.gnu.org/pub/gcc/infrastructure/"，可以分别从如下链接进行下载：

GMP 4.2+: ftp://gcc.gnu.org/pub/gcc/infrastructure/gmp-4.3.2.tar.bz2

MPFR 2.4.0+: ftp://gcc.gnu.org/pub/gcc/infrastructure/mpfr-2.4.2.tar.bz2

MPC 0.8.0+: ftp://gcc.gnu.org/pub/gcc/infrastructure/mpc-0.8.1.tar.gz

根据提示的顺序分别安装GMP，MPFR和MPC：

step1: ./configure --prefix=/usr/local/gmp-4.3.2; make install
