相关旧帖：【总结】crosstool-ng使用心得和注意事项
在之前配置完毕crosstool-ng后，就可以去编译了。
ct-ng build
然后，如果顺利的话，过一定的时间，你就可以编译完成，得到对应的交叉编译器了。

ct-ng build总共所耗时间 |
|---|---|
|
此处crosstool-ng的编译总体花费时间，取决于你的总体配置，机器性能等因素。 比较老的一些电脑，估计会在3,4个小时，甚至更多的时间。 目前多数电脑的性能，平均在1到2个小时前后。 比如，我之前的一次编译： 【记录】在Ubuntu下用crosstool-ng编译xscale的交叉工具链 就花费了72分钟。 |
例 4.1. 正常输出的log信息
此处，贴上，我之前：
【记录】在Ubuntu下用crosstool-ng编译xscale的交叉工具链
的成功编译的输出的内容（去除之前错误，合并正常的输出后的结果）：

想要在编译的时候输出所有的信息 |
|---|---|
|
根据之前第 3.1.1 节 “用ct-ng help查看所拥有的功能”中的介绍，通过加上V=2参数，可以实现，即输入，默认就输出的，人类可读的信息，也输出内部执行的那些命令。 如果有需求的话，为了编译出错时，可以直接方便的看到所正在执行的命令，是哪个出错了。 （就不用去看对应的，当前文件夹下面的build.log了） 那么可以自己去试试，加上V=2的效果，即： ct-ng build V=2 的效果。 |
