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.
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"?
