arm toolchain script

Dragonfly

i attach two arm toolchain build scripts here. anybody has interest can try them.

Dragonfly

ft, i attach them but failed. i have to post here.

回家了,就一直没有来
好不容易来一次,就发现了好东西
谢谢你啊
我想问个非常低级的问题,就是arm toolchain build scripts 该怎么建立啊,需要用什么工具

Dragonfly

this is two shell scripts. u save them as two files, then +x in file mode. then run it.
but before this, u need download binutils. glibc, gcc, with right version and patches. there are still problems u will meet. but i do not have time to well document it. bascially, u need
1) download all files 2) get a kernel 3) build toolchain use scripts and hack them when need, 4) test the built chain.

Dragonfly老大，有个问题我觉得很奇怪。我只用过两种arm，一快板sa，一块是arm7。我从来没有在建立交叉编译器上遇到什么困难。编译的时候也只不过换换命令而已。所以我不大明白为什么要这样讨论交叉编译器。我想一定是我哪方面欠缺，或者大家普遍用的硬件不是我所知道的？我倒是希望碰到一些问题，但问题是没有。另，最近比较忙，有一段时间没上来，竟看见多了这一版，真高兴！以后要常来。
