Thank you, Manaut. That indeed was my problem, it runs fine making that
change.
gr-fosphor is such an incredibly useful tool, it's painful to do without.

Have updated to gnuradio 3.7.5git-194-g76a271ac, seems to run fine.
I rebuilt / reinstalled gr-fosphor. No problems with the build. The
location of Nvidia's OpenCL library
changed from Ubuntu 13.10 to 14.04. The cmake command was:
cmake ../ -DOPENCL_LIBRARY=/usr/lib/x86_64-linux-gn

I had this problem a couple weeks ago. After deleting the build
subdirectory and rebuilding it went away until today
when it came back. I deleted the build directory and
re-cmake/make/install/ldconfig, but the problem will not clear.

Hi Tom, Thanks!
Deleting the gnuradio/build directory, then rebuilding fixed the issue.

Hi Jon - I made a bash script to do a more or less complete removal, based
on a something Jonathan posted several years ago. It's a bit pre-3.7
centric, but seems to get the job done (even with 3.7).

Hi Ali - some sinks care about the amplitude, and others do not.
For example, the instruments built into gnuradio (Scope, Frequency display,
etc.) can examine a signal of almost any amplitude within floating-point
range because you can adjust the display scale factor.
However other sinks, such as
t. Changed to gmail
to avoid the problem.

Hi John.
In a command window, type
gnuradio-companion
That will launch grc. While it's open, you will have an icon on the left-hand
icon bar.
Right click the grc icon, and lock it to the launch bar, then you'll have an
icon in the future.
