Subject: [Qemu-devel] enable-gprof configuration option issue?
Date: Wed, 4 Nov 2015 17:45:02 +0100	[thread overview]
Message-ID: <563A360E.3060506@huawei.com> (raw)

Hello,

we are trying to use good old gprof to profile the QEMU process,
and it seems to work when directly passing "-O0 -pg" using --extra-cflags,
while it does not seem to work when using "--enable-gprof".

The error we get when using --enable-gprof is the following:

ld: gcrt1.o: relocation R_X86_64_32S against `__libc_csu_fini' can not be used when making a shared object; recompile with -fPIC
gcrt1.o: could not read symbols: Bad value

We got this on a few X86 boxes with different distros, in my case I have Slackware-14.1 64bit, ld 2.23.52.0.1.20130226, gcc 4.8.2

Is the expectation that one should pass "-pg" directly?

Thanks!

Ciao,

Claudio
