Till Toenshoff commented on MESOS-1010:
---------------------------------------
The issue is indeed nasty - ran into it myself just now, after having gflags
installed (on OSX via homebrew).
After fixing this by temporarily uninstalling the gflags distribution, I ran
into the next, equally nasty issue;
I had leveldb preinstalled as well and its distribution linked against
libsnappy. As the mesos-python module does not link against that library, I
once again got missing symbols when running make-check;
__ZN6snappy11RawCompressEPKcmPcPm (snappy::RawCompress(char const*, unsigned
long, char*, unsigned long*)).
I think that do need a proper fix for this situation as it renders the
python-binding unusable for developers that build mesos out of the sources but
have gflags and/or leveldb installed.

> Key: MESOS-1010
> URL: https://issues.apache.org/jira/browse/MESOS-1010
> Project: Mesos
> Issue Type: Bug
> Components: build, python api
> Environment: Fedora 20, amd64. GCC: 4.8.2.
> Reporter: Nikita Vetoshkin
>
> In my environment mesos build from master results in broken python api module
> {{_mesos.so}}:
> {noformat}
> nekto0n@ya-darkstar ~/workspace/mesos/src/python $
> PYTHONPATH=build/lib.linux-x86_64-2.7/ python -c "import _mesos"
> Traceback (most recent call last):
> File "<string>", line 1, in <module>
> ImportError:
> /home/nekto0n/workspace/mesos/src/python/build/lib.linux-x86_64-2.7/_mesos.so:
> undefined symbol: _ZN6google14FlagRegistererC1EPKcS2_S2_S2_PvS3_
> {noformat}
> Unmangled version of symbol looks like this:
> {noformat}
> google::FlagRegisterer::FlagRegisterer(char const*, char const*, char const*,
> char const*, void*, void*)
> {noformat}
> During {{./configure}} step {{glog}} finds {{gflags}} development files and
> starts using them, thus *implicitly* adding dependency on {{libgflags.so}}.
> This breaks Python extensions module and perhaps can break other mesos
> subsystems when moved to hosts without {{gflags}} installed.
