Initially got errors when attempting to build 0.9.4-rc3 on F9 of the form:

/usr/bin/ld: 
/usr/lib/gcc/x86_64-redhat-linux/4.3.0/../../../../lib64/libbfd.a(archures.o): 
relocation R_X86_64_32 against `a local symbol' can not be used when making a 
shared object; recompile with -fPIC
/usr/lib/gcc/x86_64-redhat-linux/4.3.0/../../../../lib64/libbfd.a: could not 
read symbols: Bad value
collect2: ld returned 1 exit status

This appeared to be due the binutils RPM being built without -fPIC on F-9
(and on RHEL 5):

https://bugzilla.redhat.com/show_bug.cgi?id=447426 libbfd binutils -fPIC

Rebuild binutils RPMs with the fix suggested on:

https://fcp.surfsite.org/modules/newbb/viewtopic.php?topic_id=53684&forum=11

I was able to get oprofile RPM built, ran the simple dejagnu runtest smoke
tests on F-9 x86_64 machine, and all the tests passed.

On RHEL-5 x86-64, i386, and ia64, built binutils with -fPIC (and installing
libtool RPM), then built oprofile without the java support and ran the
tests. The smoke tests worked okay on the i386 and x86_64. Need to
take a closer look at what is going on with the smoke tests on ia64
(RHEL oprofile-0.9.3-16.el5version worked much better); the underlying
pfmon appears to work on the ia64 machine, but the new oprofile is getting the
following error in ia64 machine:

Couldn't allocate hardware counters for the selected events.


The detailed cpu types used for the tests.
