Package: qprof
Version: 0.5.1-3
Severity: important
qprof, as it is beeing packaged at this time, do not use libpfm{2,3}
when using hardware events for sampling. Actually, qprof print not
warning and fall back to the "timeout sampling".
In addition, when using the -s option, ld cannot find a symbol from
libunwind.
About perfmon:
- -DHW_EVENT_SUPPORT needs to be specified into CFLAGS when running
configure
- qprof_utils_libpfm(2,3}.c needs to include headers from perfmon2 and
perfmon3 and not perfmon
- these same files need to open libpfm2.so.2 and libpfm3.so.2 and not
libpfm.so.2 and libpfm.so.3
About libunwind:
libunwind provided by GCC do not exports all the symbols that are
declared in libunwind.h and other files (but used by
qprof_utils_libpfm{2,3}). You need to link agains the library provided
by the libunwind7 package. The correct LDFLAG at linking stage is
-lunwind-generic instead of -lunwind
The enclosed patch correct these errors and include the modification
from bug #294784. Thus you just have to apply this patch to correct
both bugs.
It would be interesting you follow up with the upstream authors to see
if it would be possible to modify the path to headers and library name via
configure instead of patching directly the sources.
Thanks,
Matthieu
