Vinod Kone commented on MESOS-1745:
-----------------------------------
So the CXX flags are not being passed properly to setup.py ? I think [~tillt]
observed something similar before?

> Key: MESOS-1745
> URL: https://issues.apache.org/jira/browse/MESOS-1745
> Project: Mesos
> Issue Type: Bug
> Affects Versions: 0.19.1
> Environment: Mac OS X 10.8.5
> clang-3.3 installed via brew
> python 2.7.8 install via brew ([GCC 4.2.1 Compatible Apple LLVM 4.2
> (clang-425.0.28)])
> Reporter: Jie Yu
>
> Here is what I have observed, correct me if I am wrong.
> To reproduce:
> {noformat}
> $ tar zxvf mesos-0.19.1.tar.gz
> $ cd mesos-0.19.1
> $ mkdir build
> $ cd build
> $ CC=clang-3.3 CXX=clang++-3.3 ../configure
> $ make
> $ PYTHONPATH=src/python/dist/mesos-0.19.1-py2.7-macosx-10.8-x86_64.egg python
> Python 2.7.8 (default, Aug 18 2014, 15:46:02)

> After digging this problem today, here is what I've found:
> 1. build/src/.libs/libmesos_no_3rdparty.a is built using clang++-3.3 with
> flags -std=c++11 -stdlib=libc++. So the mangled MesosSchedulerDriver
> constructor symbol is like the following in libmesos_no_3rdparty.a
> {noformat}
> [tw-mbp-jyu build]$ nm src/.libs/libmesos_no_3rdparty.a | grep
> MesosSchedulerDriver
> ...

> build/src/python/build/temp.macosx-10.8-x86_64-2.7/native/mesos_scheduler_driver_impl.o
> is built using clang++-3.3 without -stdlib=libc++

> As a result, it expects a mangled MesosSchedulerDriver constructor symbol
> like the following:
> {noformat}
> [tw-mbp-jyu build]$ nm
> src/python/build/temp.macosx-10.8-x86_64-2.7/native/mesos_scheduler_driver_impl.o
> | grep MesosSchedulerDriver
> U
> __ZN5mesos20MesosSchedulerDriverC1EPNS_9SchedulerERKNS_13FrameworkInfoERKSs
> ...
> {noformat}
> 3. As a result, the above symbol will remain 'unresolved' in _mesos.so, and
> subsequently causes issue when we 'import mesos' using the egg.
