按照下面这个帖子里的说法编译uClinux-dist-20070130 在skyeye下运行
http://skyeye.wiki.sourceforge.net/uClinux#tocuClinux0

这个帖子里的步骤总结一下：
1、安装 arm-linux-tools-20061213.tar.gz 工具链；
2、解压缩 uClinux-dist-20070130.tar.gz ；
3、"make menuconfig", select GDB/Armulator 和 linux-2.6.x  option.
4、然后
      make CROSS_COMPILE=arm-elf- dep
      make CROSS_COMPILE=arm-elf-
5、就可以运行了 "skyeye -e linux-2.6.x/linux" .

事实上这个做法是不行的：
1、尽管解压 arm-linux-tools-20061213.tar.gz 到了正确的位置，但是在 make 时提示gcc too old。
    奇怪的是，既然制定了 CROSS_COMPILE=arm-elf-，为啥装的工具链不是 arm-elf-前缀的？
    估计 arm-linux-tools-20061213.tar.gz 里面根本没有需要的 arm-elf-gcc，所以 make提示gcc 版本问题。

2、在 make menuconfig 时吧 uClinux 的版本换为 2.4.x，这次编译通过了，但是 skyeye 运行时提示找不到
    romfs.img，
   原因是 skyeye.conf 里有下面这句：
mem_bank: map=M, type=R, addr=0x01400000, size=0x00400000, file=./romfs.img
  事实上 make 后根本没有生成这个文件。所以出现错误提示。

3、按照 make lib_only, make user_only, make 的顺序编译 （都指定 CROSS_COMPILE=arm-elf-）
   这次前两个编译通过，make 却又报错，错误提示见后
  这次解决不了了，奇怪的是前面直接 make dep 再 make 却又为什么能编译通过。

这次试了网上 N多个帖子的在 skyeye 下运行 uClinux 的方法，无一例外全部都失败了。即使
每次都用和这些帖子中完全相同版本的所有工具和源码。包括这一次来自 skyeye Wiki的。
难道真像某人所说是我用的 Redhat 9 的问题？

正在下载 FC7，估计明天才能下完。
本来想用 Cygwin试试，但是 Cygwin 下载太麻烦了，也太大了。
这个帖子里有个裁剪好的版本 cygwin-for-skyeye-allinone.tar.bz2 ，不到100M，
http://www.linuxfans.org/bbs/thread-132451-1-1.html
但是这个网站似乎死去很久了。google了一下，居然网上所有提到 cygwin-for-skyeye-allinone.tar.bz2
的连接都指向这个已经不存在的 gro.clinux.org。谁知道这个网站究竟怎么回事，有没有可用的镜像？

晕 你的问题真多！
如果你只是想运行下hello类似的程序，看看论坛里的帖子里面的照片就行了；
否则就好好google你发现的问题，想想每一步操作是为什么，为什么！！

看上去楼主你的编译器和你当前编译的程序使用了两种不同的 float abi 。
