Re: [microblaze-uclinux] kernel compilation error: 'vmlist_lock undeclared'

[Anand Shivhare <anand.shivhare@xxxxxxxxx>]

Hi David,

   I have got a spartan-3 1500 board from nu-horizon, (sent by you)
and currently working with uClinux. I am having problem with
compilation of gdbserver. I want to use it for debug my own user
application. please help me.
   Is there any other way to debug user application?

Please help me.
