configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+.

---

一、错误发生情景：

　　在安装gcc时，执行.configure命令，报以下错误：

...省略 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.

二、错误原因：

　　错误信息中说明，安装gcc需要这三个依赖：GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+。

三、解决问题：

　　错误信息，提示了下载页面的地址：ftp://gcc.gnu.org/pub/gcc/infrastructure/。

　　所以去下载相应的包，进行安装。

　　1、打开链接：ftp://gcc.gnu.org/pub/gcc/infrastructure/。

　　2、找到需要的三个包地址，下载下来：

　　　　　　wget ftp://gcc.gnu.org/pub/gcc/infrastructure/gmp-6.1.0.tar.bz2

　　　　　　wget ftp://gcc.gnu.org/pub/gcc/infrastructure/mpfr-3.1.4.tar.bz2

　　　　　　wget ftp://gcc.gnu.org/pub/gcc/infrastructure/mpc-1.0.3.tar.gz

　　3、安装GMP：　　　　　　

tar -jxvf gmp-6.1.0.tar.bz2 cd gmp-6.1.0 ./configure make && make install

　　4、安装MPFR：

tar -jxvf mpfr-3.1.4.tar.bz2 cd mpfr-3.1.4 ./configure make && make install

　　5、安装MPC：　

tar -zxvf mpc-1.0.3.tar.gz cd mpc-1.0.3 ./configure make && make install
