Many of the following "CPU does not support ARM mode" errors in config.log.

Try to remove/change flags. I think -march option should be armv7-a and not armv7 only. You can also try to add -mcpu=cortex-A9. Guillaume -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

FYI, I've done some tests on signal processing software and those flags don't make a measurable difference for the programs I benchmarked.

This page has a wordy explanation why they make little difference unless the code is written for neon. http://wiki.debian.org/ArmHardFloatPort/VfpComparison

I believe gnuradio had some issue where I had to set the flag to use hardware floating point else the code wouldn't compile. It had something to do with how cmake set the flags.
