I have a suite of fortran code that I compile with f2py and use as a plugin to a python package. I am using Python v2.7 from Anaconda. When compiled using numpy v1.11.3 or lower, everything works fine, but if I upgrade to any more recent version I begin running into a runtime error. Presumably I am just not linking something that needs to be linked, but I'm not sure what library that would be.

The error:

ImportError: .../libstddev_kernel.so: undefined symbol: _gfortran_stop_numeric_f08

Where libestddev_kernel.so is built using this command:

f2py --fcompiler=gnu95 --quiet --opt="-O3" -L. -L/usr/lib -I. -I.../include -I/usr/include -m libstddev_kernel -c stddev_kernel/stddev_kernel.f90 config.o

Is there something additional I should be linking to within numpy or my anaconda installation?

Thank you,

Jeremy
