What variants are you using for the build? -- Ticket URL: <https://trac.macports.org/ticket/50950#comment:2> MacPorts <https://www.macports.org/> Ports system for OS X

There had been some issues about CPU architectures in the past, but that does not seem to be that. It seems that some symbols are missing from lapack, but I don't have a good clue of why at this point. The mix between clang and gcc is because of the need of a fortran compiler for lapack, and we are using the gcc5 one by default in the clang variant. -- Ticket URL: <https://trac.macports.org/ticket/50950#comment:4> MacPorts <https://www.macports.org/> Ports system for OS X

I just noticed that the missing symbols consist of a very specific subset of lapack functions, namely the matgen module, located in testing. I'll have to look in more details, but it is possible that a difference in configuration either prevents lapack of building this module, or triggers OpenBLAS to link to it. -- Ticket URL: <https://trac.macports.org/ticket/50950#comment:8> MacPorts <https://www.macports.org/> Ports system for OS X

So, I guess the issue is fixed. -- Ticket URL: <https://trac.macports.org/ticket/50950#comment:10> MacPorts <https://www.macports.org/> Ports system for OS X

Then cleaning the install and rebuilding led to a full install, so it is clearly a non-reproducible error. To answer my own questions:

1. Are there object (*.o) files in SRCDIR/lapack-netlib/TESTING/MATGEN? Yes, the object files are present. 2. Could you post the following files here (after build failure)? - SRCDIR/Makefile.conf - SRCDIR/lapack-netlib/make.inc No sign of any NOFORTRAN symbol.

It therefore seems to be an error either in ar when building the static library which misses symbols, or a linking issue when making the dynamic library. -- Ticket URL: <https://trac.macports.org/ticket/50950#comment:12> MacPorts <https://www.macports.org/> Ports system for OS X
