Re: [Discuss-gnuradio] Crosscompile Gnuradio for Rpi

[West, Nathan]

Something about your compiler/assembler flags is screwed up. I know very little about the ubuntu/debian builds, but I seem to remember some detail about them compiling everything with unexpected flags which may result in this happening. Copy output from 'gcc -Q --help=target' to fpaste.org along with output from 'make VERBOSE=1'

It doesn't sound like you care very much about actually compiling gnuradio yourself. The easiest thing to do will be to run raspbian and apt-get install gnuradio. (http://www.rs-online.com/designspark/electronics/eng/blog/taking-the-raspberry-pi-2-for-a-test-drive-with-gnu-radio-2)
