#40592: openblas: no such instruction install errors -------------------------------+---------------------- Reporter: Deil.Christoph@… | Owner: nicos@… Type: defect | Status: assigned Priority: Normal | Milestone: Component: ports | Version: 2.2.0 Resolution: | Keywords: Port: openblas | -------------------------------+---------------------- Comment (by nicos@…): Right, after some search, the Apple assembler cannot handle AVX instructions, which is why it fails. Clang seems to be the only compiler able to deal with these instructions. The attached Portfile version should compile in all cases, by disabling avx for gcc compilers, but at the cost of performance, and adding a clang version which hopefully could compile avx instructions. I couldn't test it though, as my processor is too old to support these instructions, but it is partly based on the Atlas port, which works pretty well. It is also still limited, as the Portfile uses a default fortran compiler without considering other usual variants. -- Ticket URL: <https://trac.macports.org/ticket/40592#comment:4> MacPorts <http://www.macports.org/> Ports system for OS X
