The above certainly won't work, because you're missing linker flags - I'm pretty sure that you must use -openmp in the linker for it to work, I'm not sure about -ipo -- but doesn't R detect all those automatically? I don't think you should put them in manually. The actual error comes from missing libguide link flags, but they may be implicit if you fix the other problem.
