Re: Accessing fortran libraries [SEC=UNCLASSIFIED]

Hmmm...  the only result I get from googling the specific symbol you’re having trouble with is at http://forums.amd.com/forum/messageview.cfm?catid=217&threadid=90399.

 

That thread suggests to me the possibility that there may be a mismatch between the version of gfortran used to build your target library and the version of libgfortran that is being loaded by the runtime linker.  If you haven’t already, check that you have all the necessary runtime libraries in place.

 

Running ldd against your target SO might help figure out which libraries might are being picked up.

Hi,

Those routines are likely to be in a fortran runtime library.  You probably need to use the RTLD_GLOBAL flag when loading your fortran SO to have the symbols resolved.


Mmmm, tried that but doesn't seem to help:
ctypes.CDLL("./libmylib_x86_64.so", mode=ctypes.RTLD_GLOBAL)
[ ... ]
OSError: ./libmylib_x86_64.so: undefined symbol: _gfortran_internal_malloc64
