制作交叉编译工具链(2)

#解压crosstool-ng

tar -jxvf crosstool-ng-1.23.0

#检查依赖，完成依赖检查后生成Makefile

./configure	--prefix /home/forlinx/crosstool/install 

#编译，编译成功后进行安装

make
make install

#添加环境变量

PATH=$PATH:/home/forlinx/crosstool/install/bin
source ~/.bashrc

#配置交叉编译工具链

cp -R samples/arm-unknown-linux-gnueabi ../build
cd ../build/arm-unknown-linux-gnueabi
mv crosstool.config .config
ct-ng menuconfig

->Path and misc options
	(/home/forlinx/crosstool/src)Local tarballs directory
	(/home/forlinx/crosstool/tools)Prefix directory	
->Target Options
	Target Architecture(arm)
	Default instruction set mode(arm)
	Architecture level(armv6zk)
	Emit assembly for CPU(arm1176jzf-s)
	-->Floatting point(hardware (FPU))

#配置完成后保存，编译

ct-ng build

编译过程中需要下载各个库，可以提前下好放在src目录，大大加快编译速度
