*** This bug has been marked as a duplicate of bug 375899 ***
Lars, what kind of problem is common for my bug and bug #375899 ?
I don't see the similarity to the bug this is marked a duplicate of. Marcin, can you reproduce this with cpufrequtils-008? You should be able to, since the cpuid code was added before -008. I can't reproduce this with gcc-4.5.2 or 4.6.1, but I see that you're using 4.4.5, so maybe that's related?
Indeed, -008 fails to compile too. I think this related to hardened gcc. Please look at those urls: http://linux.derkeiler.com/Newsgroups/comp.os.linux.development.system/2008-01/msg00173.html , http://comments.gmane.org/gmane.linux.oprofile/9684 .
Thanks. I've got a good idea how to fix it, thanks to the first link you gave.
(In reply to comment #3) > Lars, what kind of problem is common for my bug and bug #375899 ? Sorry I did this by mistake. Of course these two bugs are completely unrelated to each other.
Created attachment 280953 [details, diff] patch to fix compilation on x86-32 with -fPIC Please give the patch a test and confirm that it fixes the problem for you.
Ok, with this patch cpufrequtils compiles cleanly.
Committed and sent upstream as well. Thanks for reporting and testing!
