制作交叉工具链

链接：

http://elinux.org/Toolchains

http://buildroot.uclibc.org/buildroot.html

http://crosstool-ng.org/

----------------------------------------------------------------------------------------------------

计划：

1.先构建crosstool-ng

2.构建buildroot，用crosstool-ng的工具链

The MPFR library is a C library for multiple-precision floating-point computations with correct rounding

MPFR is based on the GMP multiple-precision library.

笔记：

crosstool-NG aims at building toolchains.

buildroot whose main purpose is to build complete root file systems, hence the name.

 

编译：

下载：crosstool-ng-1.9.3.tar.bz2   http://crosstool-ng.org/download/crosstool-ng/ ，解压。

./configure --prefix=/root/crosstool-ng/crosstool-ng-1.9.3-install

make;make install

mkdir crosstool-ng-1.9.3_build

cd crosstool-ng-1.9.3_build

cp ../crosstool-ng-1.9.3-install/lib/ct-ng-1.9.3/samples/arm-unknown-linux-gnueabi/crosstool.config .config

ct-ng menuconfig //一定要在上面建立的crosstool-ng-1.9.3_build目录下运行

明天继续：
