Hi,

这是你提交错误信息的几个回复及其原因。

问题一：提示机器不支持 x86 汇编代码编译。
回复：因为原来写的检测脚本忘了去掉 BFD_LIB，所以检测错误的以为不支持 x86 ASM，其实是支持的(在
utils/scripts/check-x86-asm.sh 中去掉 $BFD_LIB)，现在 SVN 上的代码这个问题已经修正了。

问题二：提示机器没有 BFD 开发库。
回复：也就是你没有安装 binutils-devel，安装了以后就没有这个提示了；其实 BFD 库在 SkyEye 中只扮演载入 elf
文件内容的角色，通过 make NO_BFD=1 后照样可以使用，现在在SVN上的代码此两者区别仅仅是没有 BFD
库时不支持新添加的反汇编功能而已，没有 BFD 也照样可以读入 blackfin,ppc,mips以及 arm 平台的 little/big
endian 的 elf 文件。

问题三：提示链接 pow,log 等函数失败以及 ppc 实现中的一个函数失败。
回复：此问题在 SVN 上的代码已经修正，解决方法为在 Makefile 中添加 -lm，在那个提示没有 ppc_xxx 的文件中注释掉那一行。
