 Posted: Thu Apr 25, 2019 10:43 pm Post subject: scipy/Numpy - extensions |
 |
|
I'm looking for a way to extend Python with SciPy /NumPy; I found these packages at SciPy.org, the documentation on scipy.org mentions ATLAS + openBLAS, as well as Cython as requirements, of which only Cython is available on OpenVMS, the rest needs to be build - in C, where I'd like to use FORTRAN
I did locate OpenVMS ports of LAPACK which includes BLAS, so if possible I'd like to use these.
I'm running HP OpenVMS 8.4 on Alpha. |

|
|
| LAPACK and BLAS have been build, I got the latest sources for SciPy and NumPy (suited for Python 2.7). which needs to be build (and probably adapted) for OpenVMS. What options should I use for C and Fortran to keep as cloise as possible to Python on OpenVMS? |

I guess p1 is scope (/PROCESS, /JOB, /SYSTEM  )
What about build_module.py and build_cython_module.py ? It seems these are C-only (where at least SciPy contains fortran code as well) and multiple sources, so linking is not always feasible. |

I have written the two small Python scripts to build quickly simple C or Cython module, but you can extend them to build any module.
