Where are you stuck?

I am native compiling on ARM under a flavor of Ubuntu. I found a
combination of binary and source was key. Some of the binary packages
are old so the pain of source was a necessary approach for those
packages. Pybombs was useful but limited. I had to customize some cmake
files.

One of the problems under ARM/Ubuntu is the system libraries are /not/
found in expected places. This was also true of some includes.
Installing (i.e., from source) wx was painful and I had to hack a header
file, IIRC. 

Getting NEON for VOLK to compile /and/ work was a bit painful. One I had
VOLK/Arm working help from this list solved one of remaining three
problems. The other two were non-problems.

I have an intensive graph running for three days. There's a problem with
one of my SDRs but it is also a problem on x86 -- debugging to do.
Otherwise, GNURadio/head works.
