Minor Description
I am seeing following failure when I try to make with following gcov flags:
export LDFLAGS="-lgcov -coverage"
export CFLAGS="-fprofile-arcs -ftest-coverage"
export CXXFLAGS="-fprofile-arcs -ftest-coverage"
Failure:
/usr/bin/ld: ../../iocore/eventsystem/libinkevent.a(UnixEventProcessor.o): undefined reference to symbol 'hwloc_get_type_depth'
/usr/lib/x86_64-linux-gnu/libhwloc.so.5: error adding symbols: DSO missing from command line
More logs:
