What blas/lapack -dev libraries do you installed when you build? I varied this over the two+ decades for the Debian build but any consistent pair of LAPACK and BLAS should work. From the aforementioned build log:
Get: 150 http://ftp.us.debian.org/debian sid/main amd64 libblas3 amd64 3.11.0-2 [149 kB] Get: 151 http://ftp.us.debian.org/debian sid/main amd64 libblas-dev amd64 3.11.0-2 [158 kB] [...] Get: 227 http://ftp.us.debian.org/debian sid/main amd64 liblapack3 amd64 3.11.0-2 [2323 kB] Get: 228 http://ftp.us.debian.org/debian sid/main amd64 liblapack-dev amd64 3.11.0-2 [4631 kB] [...] Setting up libblas3:amd64 (3.11.0-2) ... update-alternatives: using /usr/lib/x86_64-linux-gnu/blas/libblas.so.3 to provide /usr/lib/x86_64-linux-gnu/libblas.so.3 (libblas.so.3-x86_64-linux-gnu) in auto mode [...] Setting up liblapack3:amd64 (3.11.0-2) ... update-alternatives: using /usr/lib/x86_64-linux-gnu/lapack/liblapack.so.3 to provide /usr/lib/x86_64-linux-gnu/liblapack.so.3 (liblapack.so.3-x86_64-linux-gnu) in auto mode I use libblas-dev, liblapack-dev as the Build-Depends in the chroot. I think these are the generic one, they provide a fallback. (And run-time I think I am defaulting to OpenBLAS most of the time.) FWIW I always found --with-blas="-lblas" --with-lapack="-llapack" a little suspicious, but maybe that is just me if this works for you we are where we wanted to be and all is good?
