kgdb环境的安装与建立

lijierson8

今天按照一篇博客进行了kgdb的安装和调试，地址如下http://blog.csdn.net/jie12310/archive/2009/09/18/4564853.aspx
但出现了如下两个问题：
1.在cilent端进行vmlinux调试，设置命令时，出现如下错误：
linux-ebia:/usr/src/linux-2.6.26 #  gdb vmlinux

/tmp/com_1: Inappropriate ioctl for device.
(gdb) target remote /dev/ttyS0

自己也按照帖子中的方法安装了socat，用替换后的串口出现如下错误/tmp/com_1: Inappropriate ioctl for device.

还麻烦 做过的高手指点 谢谢了

kgdb调试太麻烦了，没啥子意思.. 还不如直接printk.
