It looks to me you're using some custom MString class?

Did you forget to link in the definition of operator<<() for
MString?

I am using the maya MString class and it shuld be linked by default....

I do something like this

MStatus compute( const MPlug& plug, MDataBlock& data )
{
MStatus stat;
MString str = plug.info();
std::cout << "--- " << str << " plug" << std::endl;
}

what could be the problem...

It looks like you forgot to link a library somewhere. YOu need to put it in the link->input fields or use the #pragma to include the library at link stage.

Are you actually sure there is a << operator defined for the MString class?

To the OP, if you changed the title of this thread to something
like "How do I link in the Maya SDK libraries?", then maybe
someone with experience can help you out.

"dll linking error" is too generic.

Sorry, but I have never used Maya SDK before...
