此工具是arm-linux-GCC交叉编译工具（cross-3.4.4），这个是我自己编译的，下载后解压到/usr/local/arm目录下，如果你有其它版本的编译器，你最好在编译其它文件时指定这个目录，我试过，我用它编译了u-boot1.2.0没有问题，这个交叉编译器编了好长时间，我之前在网上搜了好长时间，但是没搜到，所以今天贡献出来，免得大家还得费时间去编译，我现在用是没有问题，如果有问题请多指教。希望热爱linux的同志们多贡献点好东西出来！-This tool is arm-linux-GCC cross compiler tools (cross-3.4.4), this is a translation of my own, after downloading unzip to/usr/local/arm directory, if you have other versions of the compiler, you the best in the other documents specified when compiling this directory, I tried, I use it to compile the u-boot1.2.0 no problem, the cross compiler made a good long time before I found online a long time, but did not found that the contribution to come out today, so everyone will have time to compile, I now use is no problem, please advise if there are problems. Hope love linux comrades contribution to point out good things!
