I am trying to build GNU Radio for Android and am having issues with the  
build process.

I first tried building GNU Radio for Android on Mac OS X 10.10.4. I was  
able to follow the directions successfully until I had to build  
gr-grand.  
When I tried to build gr-grand I got this error (see error 1). I have  
tried  
searching for this error, but have not found any useful information from  
my  
search. I am not sure if this is an error with the build procedure, or  
if  
it is an error with the Android NDK and Python.

I then tried building GNU Radio for Android in a Ubuntu 14.04 64 bit VM,  
but when trying to stage Boost (./b2) I get this output from Boost (see  
error 2) and get an error about -march=armv7-m not being a supported  
compiler flag when Boost starts compiling. I have tried adding the  
toolset=gcc-android to Boost but this did not fix the problem (I had to  
do  
this on Mac to get Boost to use the configuration in the user-config.jam  
file).

I would like help getting this working, as I really want to get GNU  
Radio  
working on Android for me.
