Re: 承上
我在编译ucosii for skyeye 的时候提示 文件 ucosii4skyeye/lib/skyeye_printf.c内的 isdigit 函数没定义，我看已经有 #include <ctype.h> 了， 需要在哪个makfile 配置文件内加个 路径 指示？
不用ulib 下的 libuc.a，改用 libc.a 和 libgcc.a 倒是可以的。
不过不算好吧！
请问大侠你的问题是如何解决的？？ 请问《Skyeye和Arm开发平台》一书上的linux-2.4.18-rmk7.tar.bz2 哪里可以下载，它与光盘上patch-2.4.18-rmk7.bz2的文件是否相同 谢谢了。
很重要的初学资料呀！ 我按照你说的方法作,为什么总出现kernel panic,无法加载根文件系统?我有romfs.img啊,在
tar sim
load 阶段都加载romfs了,
run 的时候就出现panic NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.
Blkmem: bad access: block=2, count=2 (pos=800, len=0)
end_request: I/O error, dev 1f:00 (Blkmem), sector 2
EXT2-fs: unable to read superblock
Blkmem: bad access: block=0, count=2 (pos=400, len=0)
end_request: I/O error, dev 1f:00 (Blkmem), sector 0
romfs: unable to read superblock
Kernel panic: VFS: Unable to mount root fs on 1f:00 I also meet this problem.
unable to read superblock and kernel panic.
God! help me!
Up 我装2.6.9也不能加载根系统, 按提示想看kernel/workqueue.c:104, 但功力不足.没法找到原因,希望各位赐教

到最后make的时候出现问题，跟了一下makefile，最后在make subdirs.

主要报错信息：

查看了一下/usr/include/bits下其实有这个头文件。
请大侠指点迷津。

uClinux网站打开好慢阿，有没有其他的地方可以下载呀？急需谢谢大家 请教一下：
我不太清楚mem_bank: 项具体是根据什么来设置的，具体需要几个段，段的开始和大小是根据什么来设定的？
