I think we have underlinking to blas here:
defsym=__gentoo_check_ldflags__=0 -fuse-ld=lld -o .libs/qrsimple qrsimple.o  ../Source/.libs/libspqr.so -llapack -lcholmod -lsuitesparseconfig -lm
ld.lld: [0;31merror: [0m../Source/.libs/libspqr.so: undefined reference to dnrm2_
ld.lld: [0;31merror: [0m../Source/.libs/libspqr.so: undefined reference to dznrm2_

It wouldn't show with openblas but with netlib it will.

Comment 3 François Bissey 2020-09-11 08:31:54 UTC

OK, this is weird, blas is detected and should be linked against but `-lblas` is missing from where it should be.
Could I have the matching "config.log" and may be "Source/libspqr.la"?
