Jeremy Lingmann commented on MESOS-898:
---------------------------------------
Hi Tim, I've been following this ticket with great interest. At a high level,
it sounds like moving to cmake will provide a lot of flexibility and I'm all
for that.
The primary goals you've stated sound reasonable to me... in particular, I
think flexibility with targeted deps and system deps will also greatly help
with the Debian packaging efforts. From your experience with condor, did moving
to cmake help facilitate packaging outside of the RHEL/CentOS world?
One more thing I'd like to mention... cmake is a *much* better solution for
Windows builds <gasp>. So if there is a long term goal to have Windows support,
it might be worth adding target operating systems to the requirements list.

> Key: MESOS-898

> Project: Mesos
> Issue Type: Improvement
> Components: build
> Reporter: Timothy St. Clair
> Labels: build
>
> This is a rather substantial undertaking, so I would want upstream
> debate+buy-in prior to full commitment. The basic premise is: upstream
> rebundles several of its dependencies in part to tightly control its stack.
> This is not out of the norm, but in order to be picked up by distribution
> channels it needs to built against system dependencies, and rebundling is
> strictly forbidden. Given that the mesos primary target platform are
> data-center distributions such as RHEL/CENTOS/SL it makes sense to still have
> bundling support for those who do not have dependencies in their channels
> "yet". This is where cmake can be win with it's uber macros
> (http://www.cmake.org/cmake/help/v2.8.8/cmake.html#module:ExternalProject).
> I do not know of any equivalent in the autotools world, other then to brew
> your own solution. I've done this type of work in the past, and completely
> transformed condor and would leverage a lot of the work that was done there.
> I currently have a tracking branch where I've started this work, but before I
> go off into the woods, it makes sense to have a debate in public.
> The primary benefits are:
> 1. Enable downstream channels to easily distro without carrying a large patch
> sets.
> 2. Still support existing "non-proper" distribution methods.
> 3. Harden / future proof dependent interfaces.
> Side Benefits:
> Audit current build mechanics.
> - Presently the language specific binding are not installed. (.py & .jar)
> - make -jX currently fails
> - optionally look in arm support.
> Costs:
> 1. Time
> 2. Potential temporary destabilization
> 3. Infrastructure around build+test may need to change.
