I'd appreciate any input on how to run gprof successfully on qemu. I'm new
to gprof and am probably missing some steps. I successfully ran gprof on a
sorting program available online, then I attempted to run gprof on qemu.
Here are the steps I take:

This seems like a good excuse to send my suggested -cpu option for the
x86 target. It is just like my previous "take 4", but fits to the newly
unified cpu_list.

How do I enable debugging?
I checked the configure file and I do not see any options for compiling with
debugging, i.e. there is no --enable-debug option. I see that the "default
parameters" section of the configure file sets: gdbstub="yes" but other than
that i do not see any other reference to d

Yep, I've seen that before.

Could anyone give me a tip in how to compile qemu to a host arm.
I have a ARM machine running debian 4.0 , i need to run a very small i386
application on this machine but i can not compile qeumu on it.
I keep getting errors.
# ./configure --target-list=i386-user
WARNING: "gcc" looks like gcc 4.x
L
That was it. I got it to work!
Thanks so much for your help :-)

Hi,
When I try to use codesourcery's toolchain arm-2006q3-27 in my Fedora
7 box I always have the following issue:
qemu: Unsupported syscall: 983045
I guess it's a problem of NPTL incompatibility. Anyway, the patch that
Paul Brook sent a while ago solves it [1].
I wonder if it can be integrated
