Description Thomas Koenig 2010-08-27 23:04:05 UTC 
It would be nice for to automatically generate Fortran
interface blocks from the C source.

Something like

gfortran -fgenerate-c-interop-blocks foo.c
Comment 1 Daniel Kraft 2010-08-28 07:26:48 UTC 
I agree, this is also something I thought about in the past.  And to be complete, we could also just do the other way round?
