Hey,
I got wired errors for a simple macro. I am following a tutorial on a sample OpenNi project. The code is ok while not using Eclipse
errors:
Invalid overload of 'CHECK_RC(nRetVal, "Find depth generator")'
'waht' was not declared in this scope
What could be wrong?
Thanks!

The 'waht' you have in the macro body doesn't match the 'what' you have
in the macro argument definition.
My guess is that the 'waht' that is being passed to cout should be
changed to 'what'
