Hi Pearu- Thanks a lot for the quick response! Regarding ignoring wrapping some utility subprograms via a directive:
But I think it would be a useful feature. So I'll add this request to my todo list.
Thanks!
Btw, if you would use scipy_distutils-style setup.py file then you can add the "only: .. :" part to f2py_options
I thought there must be something like this; thanks for spelling it out.
I am not sure if I follow you correctly here but when using f2py from its CVS, all fortran objects have _cpointer attribute that is a C pointer to the actual Fortran or C function.
Well, I'm not sure I've followed you, either. 8-) Here's what I'm trying to do. I have fortran functions and subroutines that need to evaluate special functions as part of what they're doing. E.g., for gamma functions, right now I just define a function "gammaln" that returns the log of a gamma function, within the fortran source of my module. But Scipy already has such a function somewhere (in the Cephes library). Is there a way I can use that Cephes function? For example, could I just figure out the appropriate Cephes call (sorting out the appropriate underscores and pointers) and write a setup.py that will let my fortran routine use the Cephes library that Scipy has installed somewhere? For performance, I'd rather not have to send my fortran module a Python callback; after all, the raw Cephes routine is sitting *somewhere*. There are other examples; another module I have needs a Cholesky decomposition in the middle of a calculation. Right now it's just hard-coded in the C for the module. I should just call the appropriate lapack/atlas routine for this, and I'd love to know how to write the C code and accompanying setup.py file to be able to do this portably without the overhead of a Python callback.
