Thanks for the reply. It appears that the problem was not the addition of "-lgcc_s.10.5 -lgcc -lSystem" (only seen in verbose gcc mode), but the inclusion of the "-lrrd". I've never tried verbose mode before so it was unfamiliar to me. For some reason the "-lrrd" was unncessary. I'm following up with the developer to see if a source fix is in order.
What is the error that you are getting? An extraneous library on the link line is not usually a big issue.
BTW, is there a way to turn on gcc verbose mode with a MacPorts flag?
You shouldn't need to.
Actually, the error was not a compile error but a runtime error in the app after install. I really don't know why the extra library was causing the problem. Maybe the developer will be able to explain. Mark
