windriver rtlinux patch


Dear All,
I applied Windriver RTLinux patch to 2.6.9 kernel and did
make bzImage. I got following error messages. Kindly help me.

Thanks & Regards.

not sure exactly what that is at windriver but the actual linux rt patches are on the kernel web page
http://www.kernel.org/pub/linux/kernel/projects/rt/
the kernel and the patch number have to match exactly

at least tell us exactly which kernel and exactly which patch and exactly how you applied the patch
and exactly the steps and command you used to get to the failure point

make bzimage is an old thing now you can just do make
that's not the problem but indicates you might be following an old tutorial

other info that might be helpful is what are you trying to do in the larger picture.
also i think those build messages are after the fact.
generally there is the word error or a file not found or something that sets stuff like this off so we need to see the output from the begining of when things went south
