编译uclinux2.6真就这么难!?? 自己到底缺哪些东西???

新人,第一步总是艰难.因为工作需要,要编译个uclinux,就这样把我给难住了.
我编译的uclinux 2.6
环境是:fedora 10
make xconfig
采用的是: GDB
ARM
linux 2.6
uclibc

结果在make 的时候出现了一些问题:
首先 no arm-linux-20070808-gcc in (/usr/kerberos/sbin:/usr/lib/qt-3.3/bin:/usr/kerberos/bin:/usr/lib/ccache:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/local/arm/usr/local/arm/3.4.1/bin/:/usr/local/arm/3.4.1/bin/:/usr/local/arm/usr/local/arm/3.4.1/bin/:/home/guningyi/bin)
大概是说这个编译器没有找到,我查了一下,是在 uClinux-dist/vendors/config/armnommu/ 下有个
config.arch 中提到了,我将其注释掉后又提示我其它的编译器版本太老.

继续编译到最后结果是出错.
