Hi,
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,\
No idea what version is packaged ...
After that tried building gr-fosphor from source like
described in the osmocom wiki.
You can't mix a gnuradio package install with a source fosphor build.
That won't work.
Press Enter to quit: [+] Selected device: GeForce
MX250
[!] CL Error (-5,
/build/gr-fosphor-D4UWhK/gr-fosphor-3.7.0.2.7b6b996/lib/fosphor/cl.c:480): Unable to share
spectrum VBO into OpenCL context
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 ...
QT Gui error:
Executing: /usr/bin/python -u /home/paul/top_block.py
File "/home/paul/top_block.py", line 75
self.fosphor_qt_sink_c_0 = Template error: #set $win = 'self._%s_win'%$id
^
SyntaxError: invalid syntax
GRC generated a bad file ... report that to the GRC team I guess.
What version of GNURadio is this ?
WX Gui error:
Executing: /usr/bin/python -u /home/paul/top_block.py
Warning: failed to XInitThreads()

[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.

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