ubuntu で gcc の configure

ubuntu メモシリーズ。

ubuntu 12.04.1 LTS で gcc の configure しようとしたら
。。。
checking how to compare bootstrapped objects... cmp --ignore-initial=16 $$f1 $$f2
checking for correct version of gmp.h... no
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.
xxx@ubuntu:~/Downloads/gcc-4.4.7$

てな感じで GMP と MPFR がないよエラーが出た。
GMP も MPFR もなんのこっちゃという感じですが、
どうやら libgmp3-dev と libmpfr-dev というパッケージが必要らしい。

ついでに他のも入れてこんな感じ。
sudo apt-get install gcc g++
sudo apt-get install build-essential libtool
sudo apt-get install libgmp3-dev libmpfr-dev
sudo apt-get update
sudo apt-get upgrade

で configure はできた。
