-march = native could be fine?
or is there something more specific?
CHOST = "armv7a-hardfloat-linux-gnueabi" should be fine ... right? |

antonellocaroli,
-march="native" on ARM started with gcc-6.
If you want to use distcc, ask gcc what -march="native" means and use that, otherwise -march="native" is good.

hi,
with -march=native I do not know why but libtools do not compile
and not even with -march=cortex-a9

fixed, there was an error in the make.conf
-march=native it works
-march=cortex-a9 does not work
use -march=native |
