windows: gr-fosphor / fosphor_python 'DLL load failed, the specified module could not be found' #58

Closed carlfarrington closed 1 year ago

carlfarrington commented 1 year ago

Hi, on Windows 11.

osmocom_fft -F, and also manually trying to use fosphor, results in this (with PYTHONVERBOSE) set:

>>> from fosphor_python import *
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<frozen importlib._bootstrap>", line 1027, in _find_and_load
  File "<frozen importlib._bootstrap>", line 1006, in _find_and_load_unlocked
  File "<frozen importlib._bootstrap>", line 674, in _load_unlocked
  File "<frozen importlib._bootstrap>", line 571, in module_from_spec
  File "<frozen importlib._bootstrap_external>", line 1176, in create_module
  File "<frozen importlib._bootstrap>", line 241, in _call_with_frames_removed
ImportError: DLL load failed while importing fosphor_python: The specified module could not be found.

I am guessing this might be that the module is built against a certain vendor's OpenCL library that I do not have? I am on an Intel laptop - 8th Gen i5-u (i5-8365U) with UHD Graphics 620. The Intel website says that the OpenCL runtime is built-in to the graphics driver distribution, so nothing to download.

I have previously used gr-fosphor on my i5-5300u Thinkpad, under Linux, with OpenCL-Intel-CPU, and it worked very well. I would like to be able to use it on my Windows laptop though.

Any ideas how I can get it working? Or some guidance on building from source? The notes on the gr-fosphor page suggest it's challenging to build on Windows.

cheers, Carl

hmm. After lots of faffing around trying (and failing) to compile gr-fosphor with Intel C compiler and VS build tools, and then vc++, I simply removed gnuradio-fosphor from the radioconda conda environment, and then installed a slightly older version, and it works!

I installed gnuradio-fosphor=0.0.0.20221223.dev+g84e9d8f

I compared the two gnuradio-fosphor packages and couldn't identify a major difference that could cause this, but I think there are other possible explanations. Can you tell what OpenCL implementation is being used when you run gr-fosphor now? In attempting to compile gr-fosphor yourself, did you happen to install any OpenCL vendor libraries on your system? And perhaps the simplest explanation: there are subtle differences between installing a package through an installer like radioconda and installing using the conda/mamba command, so maybe using the latter approach is what actually got it working? Have you tried installing the latest version now with conda/mamba?

Hi ! 1) for Windows 10, the solution proposed here with downgrading to 0.0.0.20221223.dev+g84e9d8f did not work. And there is no particular confidence that it will work at all. 2) There is not even a simple description in the solution, which version of the radioconda was installed? Has a fosphor sink worked in gnuradio companion? Alexander
