Re: [f2py] integers = 2226756?

            I (finally) found a resolution to this which I'll post in case
anyone else runs into this problem (linking external libs on Windows x64) in
the future. In order to make F2PY link with my 3rd-party libs and its own
internal pieces I had to alias my Fortran subroutine as: 

 

!DEC$ ATTRIBUTES C, DECORATE, ALIAS:'test_' :: test

 

            It turns out that ATTRIBUTES C causes an incompatibility in how
data is passed between the various layers. By changing this to:

 

            !DEC$ ATTRIBUTES ALIAS:'test_' :: test

 

            I was able to make everything work. In addition
'/assume:nounderscore' was added to the Fortran compiler flags and
/Qlowercase was removed. If one has the source code for the external lib to
be linked this can all likely be avoided. For those (like me in this
situation) who do not these linking gymnastics may be necessary on Windows
platforms depending on how the lib was built.

 

            Good luck,

            ~Mike C.

Try 

integer*8, intent(in) :: N
