Summary
collectd.conf
Steps
Results
Status
1Verify intel_pmu compilation is skipped and collectd is successfully compiled and installed when jevents is installed without cFPIC flag-

  1. Build jevents without specifying cflag option.

    cd jevents
make
make install
  2. Build collectd without --with-libjevents argument.
    ./build.sh
./configure --enable-syslog --enable-logfile --prefix=/root/orest/install --enable-debug
make

    make install

  3. Make sure that collectd installation is completed and intel_pmu compilation skipped.

Collectd compilation fails and intel_pmu plugin compilation is not skipped.

FAIL
