[Discuss-gnuradio] Problem compiling on "Raspbian wheezy".

[Andrew Back]

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
