[BIOSAL] Minimal build of thorium actor applications

Tue Nov 4 16:52:39 CST 2014

There's one other thing I wanted to put on our radar.

While working with Eclipse CDT (and other IDEs), it is becoming apparent
that having the build objects appear in the same folders as the source is a
bit less than desirable. Most C/C++ projects tend to overcome this by
having a separate build folder. We should try try to build to an external
directory, e.g. build/<target>, where <target> is a configuration, and
"build" is a peer directory of "src". (We presently don't have an src
subdirectory, but this is ok.) This would allow us to keep the .o/.obj
files out of the project view when inside of an IDE. As I'm sure you know,
it also makes for an easier "clean" rule (rm -rf build/<target>).

Again, none of what I'm writing is a bug per se. It's just that I'd like to
find a way to make it better for different ways of using the source code
(or development workflows, as I like to call them).

It seems like the current Makefile structure lends itself to doing this
change, since you are building up a list of files and then compiling all of
them (presumably from the top level). But I might be missing something.

Anyway, I'll discuss this with you tomorrow, among other topics we have on
our regular agenda. I can make an issue in our GitHub tracker for this, but
I thought it would be good to discuss this first. We do have other
priorities, so this is not urgent but one of those things that would put us
on par with toolkits like MPICH, Globus, etc.
