[kepler-dev] questions about matlab actor in 64 bit window 7.

Hi Jianwu,
No worries about bothering me while traveling, it just means
that I have spotty connectivity.

I'm discouraged by the problems with creating JNI shared libraries,
it means that we have write once, recompile many times and test many
times.  In another project, we are using JNA as an interface to OpenCV.
Perhaps JNA would allow us to move away from compiling our own dlls.

The Cygwin situation is making it increasingly difficult to do development
under Windows with gcc.  The Cygwin developers seem to be mostly under
Linux and not actually use Cygwin for development under Windows.  (Otherwise,
why would they insist on Unix line endings for the default mounts?)  Sigh.

It looks like gcc is working for you.  I have some hacks into configure
for checking to see if malloc_size() is present, but I need to test them.
Realistically, at best it will be tomorrow before I can make headway here.

I think a good interface to Matlab is very important to Kepler and appreciate
the time you are putting into it.  I made some comments earlier about
the Matlab demo in 2.0.  It would be nice if the instructions were enhanced
so that a non-developer could set up Kepler with Matlab.  This requires
things like possibly updating DYLD_LIBRARY_PATH etc.
