Hello,
I'm trying to compile a fresh copy of GNU Radio from Git on a
Raspberry Pi running Raspbian wheezy [1] and encountering some
problems. I seem to have got round the first by setting -mfpu neon
when running cmake:
cmake -DCMAKE_CXX_FLAGS:STRING="-mfpu=neon"
-DCMAKE_C_FLAGS:STRING="-mfpu=neon" ../
But now it's crashing out at 68% when "Generating
atsci_viterbi_mux.cc" — paste below.
Can anyone suggest a possible fix? And let me know if more
debug/environment information is required.
Regards,
Andrew
