RE: [microblaze-uclinux] kernel compilation error: 'vmlist_lock undeclared'
Hi Anand,
2 Things:
1) A general question to you and the group,
What happens if you try and remotely debug a user-space application
the way you debug the booting kernel? (That is, using the gdb-server built
into XMD, as opposed to one running on the target.)
2) As you can see from John's reply, below, as well as the many messages on
this topic, which have come through the list in the recent months, this is
not a quickly solved problem. Regrettably, I'm unable to provide any sort of
"quick fix" for this one.
