因为太菜了，费了很大的劲才安装好
首先下载arm-elf-tools-20040427.sh
安装时出错
errors:tail : cannot open `+43' for reading : No such file or directorygzip:stdin: not in gizp formattar: This does not look like a tar archivetar: Error exit delayed from previous errors
后来google了一下，发现应该先修改环境变量
export _POSIX2_VERSION=199209 再执行就OK了 参考资料： http://www.linuxfans.org/bbs/thread-50744-1-1.html http://blog.21ic.com/user1/3912/archives/2007/36611.html http://www.linuxquestions.org/questions/linux-newbie-8/tail-cannot-open-`-43-for-reading-no-such-file-or-directory-707702/
