Cannot build on a Raspberry Pi 4

[wibimaster]

Hi !

I built successfully (after adding gfortran on the Dockerfile) on a x86-64 Intel architecture with Ubuntu 19.04.

But it fails when I try on a Raspberry Pi 4 (Raspbian Buster) :

E: Unable to locate package intel-mkl-64bit-2020.0-088
E: Couldn't find any package by glob 'intel-mkl-64bit-2020.0-088'
E: Couldn't find any package by regex 'intel-mkl-64bit-2020.0-088'
/opt/kaldi/tools/extras/install_mkl.sh: MKL package intel-mkl-64bit-2020.0-088 installation FAILED.

Is there a way to fix / bypass / avoid that ?

Thanks !

change mathlib in kaldi to ATLAS/CLAPACK/OPENBLAS. See https://github.com/kaldi-asr/kaldi/blob/master/src/configure for what to use, Kaldi repo changed default to MKL.

cd /opt/kaldi/src && ./configure --shared --mathlib=ATLAS && \
