I posted this before a few days ago but have received no replies.
Previously I developed a pretty simple Fortran in Xcode and ran it without any real problems (OS X 10.10) as command line. Now it will build but not launch. I have upgraded to Xcode 7.1.1 but no difference. I have upgraded the compiler to the 2016 version .Although I have not tried it before i have t just run the compiler from the command line and get this result.

Undefined symbols for architecture x86_64:
"_ts2932_", referenced from:
_MAIN__ in ifortzaBFY5.o
ld: symbol(s) not found for architecture x86_64
Environment variables? Does anyone have any ideas - this is really frustrating. Thanks
