craycc and OpenCV

Question

I'm trying to compile a simple hello world type program that reads an image file with OpenCv while MPI is initialised using. It works fine with gcc (mpicc), but I'm trying to use craycc for reasons I won't get into. When I do this, I get an errors that all the libraries are not found. It seems to be looking in a strange path.

Can anyone take some guesses at what's happening here? Could my pkg-config opencv.pc file be giving the wrong path? Is the typedef error triggering this (when I find the line and comment it out the warning disappears by the missing libraries remain)?

I'll try sleeping on it and see what comes up. Thanks for taking the time to read this folks, and I'll be sure to report back if I find anything.

Solved this by adding a -dynamic flag when compiling.
