Hello,
I'm experiencing trouble installing gr-fosphor on my new laptop using
ubuntu 18.04 LTS
Fist installed opengl/cl drivers, gnu-radio over the package manager, and
gr-fosphor also with package manager,
After that tried building gr-fosphor from source like described in the
osmocom wiki.
Also tried fresh ubuntu install with gnuradio an gr-fosphor using
pybombs.this seems to fail the same.
Although my old laptop runs fosphor (3.7.13.4) fine under just intel's
openclas well as my old workstation with just nvidia fosphor, (3.8.0.0)
This new install won't with either combination i try.
who can help me out or point me in the right direction solving this?
Thanks in advance, Paul
Here is a description of what i did on the last try :

Hi,
I'm experiencing trouble installing gr-fosphor on

No idea what version is packaged ...

You can't mix a gnuradio package install with a source fosphor build.
That won't work.

This should definitely be fixed with the FLG_FOSPHOR_USE_CLGL_SHARING
patch ... if this is set to 0, then the codepath where that error is
printed is not even called ...

What version of GNURadio is this ?

Make sure that the XInitThreads call is first in the generated py file.

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

Hi,
Got it working installing gnuradio from pybombs and
gr-fosphor from source, indeed had to change FLG_FOSPHOR_USE_CLGL_SHARING to 0
Yeah, the nVidia driver is annoying ... it used to work and they broke
it a few years ago and they don't care enough to fix it.
And since I got a new laptop a few years back, I don't have a nvidia
card to debug or work around it.
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
fosphor doesn't support 3.8 yet.
And at first it will only support GLFW probably. (WX has been removed
and switch to Qt5 is annoying because Qt changed API substantially and
there is just no way to do what I did in Qt4 at all in Qt5).
Cheers,
Sylvain
