crosstool-ng-1.22.0搭建开发环境

 
 

Ubuntu16.04无法安装libtool，只能在Ubuntu14.04以下版本安装。

cp 下载/crosstool-ng-1.22.0.tar.bz2 /home/hou/

tar -xvf crosstool-ng-1.22.0.tar.bz2

cd crosstool-ng

 
 

安装一些必要的软件：

apt install gperf bison flex texinfo help2man gawk libtool libncurses5-dev

Make

./configure --prefix=/home/hou/arm/crosstool-ng-1.22.0_install

在~/.bashrc 配置ct-ng命令的环境变量

目录：

love-xin :: ~/arm/crosstool-ng-1.22.0_build % ct-ng list-steps

Available build steps, in order:

- libc_check_config

- companion_libs_for_build

- binutils_for_build

- companion_libs_for_host

- binutils_for_host

- cc_core_pass_1

- kernel_headers

- libc_start_files

- cc_core_pass_2

- libc

- cc_for_build

- cc_for_host

- libc_post_cc

- companion_libs_for_target

- binutils_for_target

- debug

- test_suite

- finish

Use "<step>" as action to execute only that step.

Use "+<step>" as action to execute up to that step.

Use "<step>+" as action to execute from that step onward.

在后续的配置（和编译）之后，可以通过show-tuple，去查看到当前配置的交叉编译器是啥样的

love-xin :: ~/arm/crosstool-ng-1.22.0_build % ct-ng show-tuple

arm-cortexa9_neon-linux-gnueabihf

查看当前有哪些（默认的）示例配置，可以用：

ct-ng list-samples

查看单个的某个示例配置的核心参数，用：

ct-ng show-<sample>

iTop4412是使用cortex-a9，所以按照这个配置就OK，上面是软件要求。

可以直接去调用此配置了：

ct-ng arm-cortexa9-linux-gnueabi

 
 

 
 

屏幕剪辑的捕获时间: 2016/5/22 13:08

接下来，你就可以去进入配置：

ct-ng menuconfig

 
 

源码包下载保存路径

Paths and misc options
(${HOME}/arm/src) Local tarballs directory

工作路径

一般使用默认配置

Paths and misc options
(${CT_TOP_DIR}/.build) Working directory

目标安装路径

 
 

Paths and misc options
(${HOME}/arm/x-tools/${CT_TARGET}) Prefix directory

一些详细的配置请参考网站：

crosstool-ng详解

 
 

src下面主要用到linux、gcc两个安装包，这两个包比较大，可以提前下载好。其它的包自动下载。

 
 

配置好后，保存退出。执行ct-ng build编译

为了不影响主机看网页、玩游戏，当时设置Ubuntu是2G运行内存，所以时间有点慢，想要快点可以设置大一点。
