怎样编译gcc-4.4.4?

首先，下载了源码gcc-4.4.4.tar.gz。

解压后的文件：

configure: error: Building GCC requires GMP 4.1+ and MPFR 2.3.2+.
Try the --with-gmp and/or --with-mpfr options to specify their locations.
Copies of these libraries' source code 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 and/or MPFR 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.


但是配置完后，并没有生成Makefile。

有那位大虾，告诉我怎么搞定哦？

Problem solved!

need install gmp and mpfr.

注意看错误信息
