When in doubt, compile by hand. What's the actual compilation line for
simplerend.cpp from OSL and testrender.cpp? The g++ lines, not the cmake foo
leading to them...

Please use a different pastebin service such as paste.ubuntu.com or pastebin.ca
or paste2.org. The pastebin.com site is inaccessible (network blocked) for
some of the devs due to a history of problems.
That said, I don't see anything glaring in your file. The only question is
whether the abstract base class was compiled into the OSL_NAMESPACE or not,
which depends on some compilation trigger.

That's pretty telling. Show the entire compilation output from the g++ line to
the final error message for both files and it should be more clear what's going
on.
