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 :



Installed ubuntu 18.04 Lts Desktop >> Default settings, 3th party drivers
enabled.

Update:


*sudo apt-get updatesudo apt-get upgrade*
Installed nvidia driver 4.30 on: "Additional Drivers" tab in "Software &
Updates":
*software-properties-gtk*
(Apply and reboot)

Installed gnuradio via package manager:
*sudo apt install gnuradio*

Installed clinfo / glxinfo:
*sudo apt install clinfo mesa-utils*

Download and install latest intel opencl runtime:




*sudo apt-get install lsb-corewget
http://registrationcenter-download.intel.com/*****/****/**/****/**/l_opencl_p_18.1.0.015.tgz
<http://registrationcenter-download.intel.com/*****/****/**/****/**/l_opencl_p_18.1.0.015.tgz>tar
xvzf l_opencl_p_18.1.0.015.tgz cd l_opencl_p_18.1.0.015/sudo
./install_GUI.sh*
(Follow steps with Defaults)
