Hi all,

When gnuradio is built, it halts as follows.

Could anyone give me a hint here?

You’ve asked for help on this, but how are we going to help you without  
any  
information about your system? Those errors are pretty obviously related  
to  
NEON and assembly (ASM) code. So you’re likely running this on an ARM  
processor, yes? What kind of processor? Native compile or cross compile?

Hi,

## Sorry for the inconvenience made. I am building GNURadio on Banana-pi. According to the suggestions on a previous thread, I went with pybomb option and now here where I am stuck. Yes. My processor is ARMv7 (rev 4

v7l). The above thread is on a native compilation. It would be  
appreciated  
if you can address this issue.

Thanks.

Zamrath N.
