Hi Konrad,

Sorry I didn't see this email earlier. 

The patch applies cleanly to oprofile 0.9.7 and builds on fc17. What was the error you got?  How are you configuring it? You should be able to do something like:

cd oprofile-0.9.7
patch -p1 -b < ~/oprofile-0.9.7-xen.patch
./autogen.sh
./configure --with-kernel-support --enable-gui=qt4 

Alternative you should be able to down load the src rpm from http://koji.fedoraproject.org/koji/buildinfo?buildID=276310

then

yum-builddep oprofile-0.9.7-1.src.rpm
rpm -Uvh oprofile-0.9.7-1.src.rpm
cd ~/rpmbuild/SPEC
rpmbuild -b oprofile.spec
