Ben, thanks so much for the help - I finally seem to have gotten things
working (or they appear to be). It was a matter of not really knowing
what I was doing in Gyp, and was linking to my files wrong. I finally
ended up building verbosely and comparing what g++ was doing for each
project and just throwing the arguments I was missing into the libraries
array in the "binding.gyp" file, and it all worked!
thanks again! Still not QUITE sure how it's all linking, but I have
more of a clue now. Despite the frustration, I learned a lot for a noob
to all of this! Working as well as it did seemed to be a red herring,
oh well
Before:
"targets": [

"target_name": "proj",

"libraries": ["../shared/libOpenNI2.so"]
}
After:
"targets": [
{
"target_name": "proj",
"sources": [ "proj.cpp" ],
"include_dirs": [ "./Include"],
"libraries": ["-lOpenNI2", "-Wl,-rpath ./"]
}

Awesome, I appreciate it! Onto the OpenNI forums! If anybody knows
otherwise I'd love to hear it so I'm not banging my head against the wall

afraid of - that this wasn't going to be possible in Node for some silly
reason.
There's one thing to keep in mind if the exceptions you mentioned are
C++ exceptions: node.js itself doesn't use them - and is in fact
compiled with -fno-rtti -fno-exceptions - so you need to catch any and
all exceptions that library code throws. If you let one through,
node.js (or rather, the C++ runtime) will abort.
I didn't think of it yesterday, but if OpenNI throws an exception at
dlopen() time (e.g. from a static constructor), it's game over. That
would be a moronic thing to do, though. For one, you'd almost
certainly leave the dynamic linker in an undefined state.
