Good question. I don't see logs for the _succeeding_ builds, so I can
only guess what's different there. I'd need to setup a build with
netlib again, but am tangled up in various tasks, including failure to
get to testing luminance-hdr for blas-related breakage because
qt5-qtwebengine is broken in multiple ways for Linux (also by pkgsrc
patches, but not only). Oh, and my actual job.

The configure of failed opencv finds Lapack with liblapack.so and
libblas.so, but does apparently use symbols it would get when linking
to libcblas. Is the succeeding build linking in the correct lib, is it
not using those symbols, or are those builds using a different BLAS?

Are bulk builds guaranteed to run with the default options?


Alrighty then,

Thomas
