Re: [Discuss-gnuradio] gr-fosphor : New RTSA-like visualization block for GNURadio using GPU acceleration

Hi Alex,

The benchmark utility source is in gr-fosphor/lib/fosphor

I had to run make manually, but in order to get it to build I had to 
bodge it.  The changes I made are in the diff below.

=======================
diff --git a/lib/fosphor/Makefile b/lib/fosphor/Makefile

=========================

I then ran make in gr-fosphor/lib/fosphor.  Then I recorded some stuff 
with grc and then invoked the benchamrk utility:

address@hidden:~/src/gr-fosphor/lib/fosphor$ ./main 
~/grdata2013.10.27.12.10.20.dat


Hope that helps.

Darren
