[jira] [Created] (MESOS-2690) --enable-optimize build fails with maybe-uninitialized

Joris Van Remoortere created MESOS-2690:
-------------------------------------------

             Summary: --enable-optimize build fails with maybe-uninitialized
                 Key: MESOS-2690
                 URL: https://issues.apache.org/jira/browse/MESOS-2690
             Project: Mesos
          Issue Type: Bug
          Components: build
         Environment: GCC 4.8 -> 4.9
            Reporter: Joris Van Remoortere
            Assignee: Joris Van Remoortere


When building with the `enable-optimize` flag, the build fails with `maybe-uninitialized' errors.
This is due to a bug in GCC when building optimized code triggering false positives for this warning. Please see:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59970

We can disable this warning when using GCC + --enable-optimize.

A quick work-around until there is a patch:
../configure CXXFLAGS="-Wno-maybe-uninitialized" <your-other-flags-here>
