and it is now fixed by https://trac.sagemath.org/ticket/28884 Please have a look. It tests OK on various Debian/Ubuntu, on (obsolete) Fedora 26 I had to supply openplas.pc, as it does not install it, and even on MacOS 10.13 with R and openblas from Homebrew it tests just fine. It should be possible to use the "native" R installation, if they supplied libR.pc (which they don't, but it should be easy to produce one). > > -- > 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+unsubscr...@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/sage-devel/CAOTD34aq42rZGp0TK0bbkFfXhmw7H%3DfV_F7aUCMiw6fZbikgdA%40mail.gmail.com. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
