Hi Kelly,

This particular set of options is not expected to work. You've
requested that the runtime be built to support 2 different fault
tolerance protocols simultaneously, where the code is only written to
enable one at a time. In their current form, it doesn't really make
sense to combine them. I also don't know how well they currently
interact with the SMP support in the runtime.

Additionally, they're both somewhat experimental, and not so much
suited for day-to-day use as yet. Unless you're building with FT for
the explicit sake of experimenting with them, they're probably not
what you want. Since you're building the OS X, I assume you're
targeting a single node, rather than a cluster (the last I knew of
shut down a few years ago), in which case the FT options don't really
do anything when the lone application process fails.

So, my overall suggestion: if you just want to write, compile, and run
Charm++ applications, drop the FT options.

We'll add a test in the code that will give a more explicit error on
these incompatible options and stop the build cleanly.

Thanks!

Phil
