Dear all,

How are you? All my attempts to compile Octave on a macOS with OpenBLAS fail. I still obtain the same error:

My configure and make script is as follows:

#!/opt/local/bin/bash

OPENBLAS_PATH=/opt/openblas

export V=1

CC=gcc
CXX=g++
FC=gfortran
CFLAGS="-I/opt/local/include -I${OPENBLAS_PATH}/include"
CXXFLAGS="-I/opt/local/include -I${OPENBLAS_PATH}/include"
FFLAGS="-I/opt/local/include -I${OPENBLAS_PATH}/include"
LDFLAGS="-L${OPENBLAS_PATH}/lib -lopenblas -L/opt/local/lib -liconv"

../configure --prefix=/opt/octave-6.2.0 --disable-readline --without-qt --without-x --with-libiconv-prefix=/opt/local

make -j 4

## @eof octave-install.sh

I also attach the `config.log` file for completeness. It seems to me neither OpenBLAS, not iconv get picked up by the configure script. Maybe I have to modify the makefile directly?

Dear all,

Thank you for all you help and your suggestions. Now I see, why linking Octave against Intel’s MKL @ macOS was a theoretical debate. I’m failing here right at the configuration stage. Please find my `config.log` file attached. I would be happy to help here and try further if you can provide me with some guidance. I think MKL at the backend would make Octave only stronger.

Regarding of my original issue of compiling Octave from source @ macOS I think for now I will follow an easier route and try to link it against the “standard” OpenBLAS. I need to progress in my project and make my life a little bit easier. I will get back to you once I try the "OpenBLAS compilation”. Thank you for your help and have a good day ahead!

Thank you very much for your help and your replies. Please find below
the contents of my configure and build bash script:

As you may see I’m trying to point Octave to Intel’s MKL BLAS and GNU
iconv library located in /opt/local/lib.

You are the only person I'm aware of who has *actually* tried to build
Octave against Intel MKL on Mac; up until now this has just been a
theoretical discussion as far as I'm aware.

Good luck!
