I am cross compiling armadillo by following Cross-Compiling Armadillo Linear Algebra Library I am using : gcc-arm-10.2-2020.11-x86_64-aarch64-none-linux-gnu to cross compile. I get following error when I execute make blaslib

Error I see

Error : as: unrecognized option '-EL'

As per my understanding build is triggering gcc x86 'as' and not arm 'as'. How to fix this error?

Configure with `--with-as=path/to/arm/as` or use `AS=path/to/arm/as make` – Osyotr Feb 21 '22 at 20:09
@Genjutsu : AS=path/to/arm/as make didn't work. Can you please elaborate how to use --with-as=path/to/arm/as? – Prabhat Sharma Feb 22 '22 at 07:10
If `configure` does support it, you can use `./configure --with-as=path/to/arm/as && make` – Osyotr Feb 22 '22 at 10:15
