我想求助一下用GCC实现MIPS交叉编译的全过程（从编译binutils开始到重新编译GCC，再到如何实现交叉编译） [复制链接]

如题，麻烦大家指导下，我是GCC和MIPS的初学者，还望大家不吝赐教：）谢谢您！

不需要这么麻烦,很简单的.
首先你去
http://www.uclibc.org/
下载一个buildroot,这是个工具集,你接下来所要做的事情就是把gcc、binutils等文件下载下来，放在buildroot下的dl目录下
当然，你也可以让buildroot自动下载，不过速度较慢。
选择目标的为MIPS，以及一些工具的版本，顺利的话，你编译完后就能得到MIPS的gcc交叉编译器了。还包括文件系统(busybox)，n多的可选应用程序(sqlite等)。

楼上的兄弟，我在make buildroot时遇到了问题，如下：

怎么解决呢？

DirkNowitzki ,你好！你是下了最新的快照的版本吗？这个可能会有点危险，我就载过快照，老外居然还没完成，所以一堆错误。
你可以试着下比较前面点的快照版本，或者用svn co去下载。如果不行的话，加我msn或者qq，我给你发过去。
buildroot不需要sudo。
另外，检测一下你的gcc是否正确，输入gcc --version看看

[fc@fcdev buildroot]$ gcc --version
