    3.4.1
最 常用的编译版本是arm-linux-gcc-3.4.1 和 arm-linux-3.3.2 的，现在的嵌入式开发基本上用的是这些，3.4.1的用于编译2.6的内核，而3.3.2的常用于编译busybox,和bootloader(u- boot),编译的版本配合不好的话就会出错，所以要选择好编译版本，如果这个版本不行的话，可以试试其他的版本,在uclinux上用的多的就是 arm-elf-tools-20030314
http://www.handhelds.org/download/projects/toolchain/arm-linux-gcc-3.4.1.tar.bz2
http://www.handhelds.org/download/projects/toolchain/arm-linux-gcc-3.3.2.tar.bz2
如 果系统中又装了3.4.1和3.3.2的版本的话，可以在 .bashrc 中通过设置PATH来指定默认的版本为GCC3.4.1，然后再打开一个新的终端就可以用了，如果需要使用3.3.2的话，可以用具体的路径指定 (/usr/local/arm/3.3.2/bin/arm-linux-)。
在~/.bashrc最后加入:   export PATH=$PATH:/usr/local/arm/3.4.1/bin   

如果编译u-boot或者busybox的时候指定3.3.2的版本：
CROSS_COMPILE=/usr/local/arm/3.3.2/bin/arm-linux-
3.4.1的就直接用arm-linux-就可以了。
arm-linux-gcc-4.2.1的版本在
http://ftp.snapgear.org:9981/pub/snapgear/tools/arm-linux/
这里可以下载，
arm-linux-tools-20070808.tar.gz
这个可能是4.2.1的版本，因为下面有编译4.2.1的方法还有相应的代码包，
build-arm-linux-4.2.1
，此版本由于过大，我没有下载。
下面的这个是ARM官方给的下载链接4.2.1的
http://www.codesourcery.com/gnu_toolchains/arm/download.html
，然后将HOST选择为IA32 GNU/Linux，点击下载就可以了。不过前缀为arm-none-eabi-而不是arm-linux-有点郁闷。
自 己编译一个交叉编译环境是个很艰难的过程，有些软件又依赖不同的版本，所以自己维护一个是相当费时费力伤脑筋的过程，关于arm-linux- toolchain,arm-elf-toochain的区别，主要是编译过程中所用的C库的不同，arm-linux用的是glibc，arm-elf 用的是newlibc,ulibc等,具体的可以去网上搜集，一般编译arm+linux的用arm-linux-,而编译uclinux则用arm- elf-
这是我在网上找到的一些下载交叉编译环境的网站
