G++ doesn't know to look for it if you don't tell it. So if the wsmp64 library was originally compiled by G77, you would need to add -lg2c at the end of this command: >>> g++ -o wgsmp wgsmp_ex1.cpp -L../lib/libgoto_opteron-64-r0.99-3.so >>>-L../lib -lwsmp64 -lpthread -Wno-deprecated However it looks like your libwsmp64 was instead originally compiled with pgf90, judging by the undefined "pgf90_compiled" references. I don't know offhand what magic incantations are needed to make G++ link against pgf90 libraries.
