Hi all- I've run into what I think might be a bug in f2py and callbacks to python. Or, maybe I'm not using things correctly. I have created a very minimal example which illustrates my problem at:
https://github.com/soylentdeen/fluffy-kumquat The issue seems to affect call backs with variables, but only when they are called indirectly (i.e. from other fortran routines). For example, if I have a python function def show_number(n): print("%d" % n) and I setup a callback in a fortran routine: subroutine cb cf2py intent(callback, hide) blah external blah call blah(5) end and connect it to the python routine fortranObject.blah = show_number I can successfully call the cb routine from python: >fortranObject.cb 5 However, if I call the cb routine from within another fortran routine, it seems to lose its marbles subroutine no_cb call cb end capi_return is NULL Call-back cb_blah_in_cb__user__routines failed. For more information, please have a look at the github repository. I've reproduced the behavior on both linux and mac. I'm not sure if this is an error in the way I'm using the code, or if it is an actual bug. Any and all help would be very much appreciated.
