Benjamin Hindman commented on MESOS-864:
----------------------------------------
Hey Till, glad to see this being taken on! I'd like to propose that we go after
C++11 before Clang. My intuition is that if we get C++11 working we can remove
all of the std::tr1 garbage in lieu of C++11 features, thus making compiling
with Clang much easier (although, with the requirement of C++11). Thoughts?
Also, see MESOS-323 and MESOS-670 regarding compilation with Clang and
MESOS-750 for the path towards C++11. The sooner that we start getting the
ability to do --with-c++11 will enable us to move to C++11 completely.

> Key: MESOS-864
> URL: https://issues.apache.org/jira/browse/MESOS-864
> Project: Mesos
> Issue Type: Improvement
> Components: build, libprocess
> Affects Versions: 0.14.2
> Environment: Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM
> 3.3svn), libc++ (_LIBCPP_VERSION) 1101
> Reporter: Till Toenshoff
> Priority: Minor
> Labels: build, clang, libc++, libprocess, stdlibc++
>
> When attempting to build libprocess against libc++ most pitfalls are simply
> namespace related (::tr1) but some are harder to come by.
> One example is the use of std::tr1::_Bind within deferred.hpp.
> [3rdparty/libprocess/include/process/deferred.hpp]
> For the specific example, a comment was given for reasoning the design choice:
> <pre>The result of invoking the 'defer' routines is actually an internal
> type, effectively just a wrapper around the result of invoking
> 'std::tr1::bind'. However, we want the result of bind to be castable to a
> 'Deferred' but we don't want anyone to be able to create a 'Deferred' so we
> use a level-of-indirection via this type.</pre>
> How could we solve this without deriving directly from _Bind?
