Not very precise, but the error "undefinded reference to ..." tells you
it can't find something, that should be there. And since $FPG_MAIN is
the first I assume you will have to pass a list of paths to ld helping
it finding the .o files missing.

There are ways to see the path list the compiler hands over to the
linker - which others will have to show you because I don't know how -
and then you can use that path list to tell the linker while trying
manually.
