这里的cc应是你的arm交叉编译器arm-elf-gcc，它可能在/usr/local/bin目录下。

你指定一下cc的值或是修改uClinux内核文件根目录下的Makefile文件的cc所指向的值为“/usr/lcoal/bin/arm-elf-gcc”。如果在上面的/usr/lcoal/bin目录下的话。

指定HOSTCC   = arm-elf-gcc 后依旧错误，不知道应该安装什么包，请指教！

un * <none>(no description available)是不是表示没这个包的意思。

安装完包后别忘了ldconfig一下！

nirvaam

un 应该是表示Unknown吧，这个包已经安装了。
已重启，并执行ldconfig。
应该是我缺少了什么步骤吧

renbagshoes

你安这个软件包是不是系统墨认的目录，如果不是的话就需要指定这个软件lib目录，然后执行一下ldconfig

And I do change it. But the error continue.
And in my .conf, I have already set this:

CONFIG_BLK_DEV_INITRD=y
So , anyone could tell me what's going wrong ?

原文的题目是Getting Familiar with uClinux/ARM 2.6，个人觉得翻译成“获取uClinux/ARM 2.6”不大妥，应该翻译成“逐渐熟悉uClinux/ARM 2.6”吧？
