Hello

Thank you for accepting me to this forum. This is my first post so please be gentle with me.

I’m struggling to get GR-Fosphor working on a Intel Core i5 machine. The OS is Ubuntu 18.04.

I have attempted to get OpenCL working correctly on this machine so that I can use GR-Fosphor. sys\_analyzer\_linux.py doesn’t ‘see’ the Intel OpenCL installation and osmocomm\_fft runs OK without the -F switch but doesn’t run with it.

The Intel website is confusing so I may not have got the correct package for OpenCL…

Has anyone managed successfully to get gr-fosphor working on Ubuntu 18.04 and, if so, how did you manage it?

Any help appreciated.

TIA.
