Hello,

I'm trying to build GNU Radio using a toolchain from Mentor Graphics (arm-none-linux-gnueabi-).

Some gnuradio dependecies i have builded manually from source using this toolchain.

<snip> 

export CC="arm-none-linux-gnueabi-gcc -mthumb -march=armv6t2 -mfloat-abi=softfp -mfpu=neon"

export CXX="arm-none-linux-gnueabi-g++ -mthumb -march=armv6t2 -mfloat-abi=softfp -mfpu=neon"

export CPP="arm-none-linux-gnueabi-gcc -E -mthumb -march=armv6t2 -mfloat-abi=softfp -mfpu=neon"

Paul,

 You appear to be targeting an processor that uses the armv6 ISA. I believe VOLK only supports armv7 at this point (although I'm uncertain if that's explicitly stated anywhere

I don't think it's possible for -march=armv6* AND to have -mfpu=neon. Check that your flags are sane for your hardware.
