 Dear Kim,
 
 Thanks for your reply.
 I am using 2.6.35 since it is my base kernel, and i have to cross check
 perf in that kernel only.
 That's why i requested..the info for how to compile perf with out any issues
 Any inputs regarding changes to Makefile to build perf successfully?
 
 Anyway..thanks for your information

You can try building a recent perf and then using it on that old kernel,
there is no need to tie perf/kernel versions, the tool notices if
features it tries to use are not present on the kernel it is being run
and acts accordingly, falling back to using the features present in
older kernels.

If it doesn't work like that, we'd like to know.

So please grab the latest kernel sources and build the tool, then
transfer the binary to your target machine and try it.

If it still doesn't build, please report here.

Do you have a sysroot for the cross-compile environment? e.g., for WRL3 
we use:


CROSS_COMPILE = i586-wrs-linux-gnu-
CROSS_SYSROOT = /path/to/cross-compile/sysroot

make CROSS_COMPILE=$(CROSS_COMPILE) ARCH=$(ARCH) CC=$(CROSS_COMPILE)gcc 
--sysroot=$(CROSS_SYSROOT)
