Hi Syvain,
Got it working installing gnuradio from pybombs and gr-fosphor from source,
indeed had to change FLG_FOSPHOR_USE_CLGL_SHARING to 0
Just for info:
No idea what version is packaged ...
Ubuntu
18.04 packs: gr-fosphor (3.7.0.2.7b6b996-2)
You can't mix a gnuradio package install with a
source fosphor build.
That won't work.
did the source build on fresh install gnuradio from package
manager and
gr-fosphor from source
The qt/wx errors where the same on :
Package manager version:: gnuradio (3.7.11-10)
pybombs version : 3.7.13.5
Havent tried the 3.8 for this
