Since I switched to Ubuntu 20.04, I am not able to get Posphor working with
osmocom_fft. I am getting the following error:
[!] gl_cmap shader compilation failed (cmap_simple.glsl)
[w] Color map shader 'simple' failed to load, will use fallback
[!] gl_cmap shader compilation failed (cmap_bicubic.glsl)
[w] Color map shader 'bicubic' failed to load, will use fallback
[!] gl_cmap shader compilation failed (cmap_fallback.glsl)
[!] Color map shader 'fallback' failed, aborting
gr::log :ERROR: qt_sink_c0 - Failed to initialize fosphor
The app is running, but the render area of the spectrum is completely
I am on your "gr3.8" branch. OpenCL is exactly the same as on Ubuntu 18.04
(I need the older 340 Nvidia driver on my old NVS 4200M, if you remember),
GLFW is the latest master. Everything compiles just fine, only at runtime
this issue presents itself.
If you have any idea, that would be lovely.
