[hpsdr] piHPSDR on Odroid C2 ?

[Sid Boyce]

Hi Tim,
I have pihpsdr running on x86_64 OK - without GPIO of course.

On PINE A64+ with Ubuntu 64-bit ARM with KL7NA's audio_out branch of 
pihpsdr it runs but there is no audio, something I am still investigating.
I have not looked into the GPIO support - said to be Pi compatible.

On ODROID-C2's latest Ubuntu image there is a mess up which they said 
would be fixed when it was discovered in the previous image. There was a 
workaround for the earlier image but the problem where 2 packages 
conflict with one trying to overwrite the other is still there.
There is also John Melton's query regarding the number of edge triggered 
GPIO interrupts available. I raised this on the ODROID forum but no one 
has so far explained whether John is correct in his analysis that there 
are only 4. The GPIO is said to be Pi compatible but differences seem to 
exist.

As usual, most distributions are light of understanding when it comes to 
the finer points of SDR though they provide hundreds of hamradio 
applications.
One case in point some years back, VirtualBox wondered why I needed 
support for 2 sound cards. I explained why Softrock required them - end 
of dialog on the subject.

The gtk+3.0 package is required to build pihpsdr but it conflicts with 
the mali-x11 package.
root at odroidC2:/usr/src/pihpsdr# make
rm -f version.o
gcc -g -D odroidC2  -D FREEDV -O3 `pkg-config --cflags gtk+-3.0` -c -o 
band.o band.c
Package gtk+-3.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtk+-3.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtk+-3.0' found
In file included from band.c:23:0:
band.h:20:21: fatal error: gtk/gtk.h: No such file or directory
compilation terminated.
Makefile:169: recipe for target 'band.o' failed
make: *** [band.o] Error 1
