Quite probably : In order to use the rjags <https://cran.r-project.org/web/packages/rjags/index.html> package (interface to the JAGS <http://mcmc-jags.sourceforge.net/> Bayesian modelling sampler, I had to use the Sage shell in order to compile and install a version of JAGS in $SAGE_LOCAL : the system JAGS choked on BLAS/LAPACK calls not available in Sage's libraries. Things would be much simpler if Sage used the systemwide numeric libraries. I *think* that this is possible when these libraries are ATLAS : pointing SAGE_ATLAS_LIB to the systemwide ATLAS library makes Sage use them. ISTR that Erik Madison Bray recommended this to compile Sage on Cygwin (but I lost the reference to the relevant Sage Wiki post...). My question was to know if this is possible when openblas provides the systemwide numerical libraries... > On Sat, 16 Feb 2019 13:40 Emmanuel Charpentier <emanuel.c...@gmail.com > <javascript:> wrote: > >> Trac#27303 <https://trac.sagemath.org/ticket/27303> needs review. >> >> Le samedi 16 février 2019 10:47:05 UTC+1, François Bissey a écrit : >>> >>> >>> >>> > On 16/02/2019, at 22:40, Emmanuel Charpentier <emanuel.c...@gmail.com> >>> wrote: >>> > >>> > I see (modulo the legendary readability of m4, which has been compared >>> to line noise or a cat's nap on the keyboard...). >>> > >>> >>> Any language is a bit like that when you don’t know it to be fair. >>> And you can produce line noise in most programming languages >>> but I’d pick perl and lisp over m4 for that. >>> >>> Do open a ticket for sqlite upgrade, there may be other interesting >>> reasons to upgrade. >>> >>> There may already be a ticket for making sqlite optional and if >>> you think m4 is looks like line noise you probably should leave >>> it to the pros. >> >> -- >> You received this message because you are subscribed to the Google Groups >> "sage-devel" group. >> To unsubscribe from this group and stop receiving emails from it, send an >> email to sage-devel+...@googlegroups.com <javascript:>. >> To post to this group, send email to sage-...@googlegroups.com >> <javascript:>. >> Visit this group at https://groups.google.com/group/sage-devel. >> For more options, visit https://groups.google.com/d/optout. >> > -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
