[R-pkg-devel] help with BLAS/LAPACK version debugging

[Ben Bolker]

   I have not sorted it out yet [cc'ing the list for the record]

Kurt Hornik said

"It seems one needs a current release version of OpenBLAS (0.3.20) plus 
a version of R-devel configured to use this for the system LAPACK"


   I finally got around to trying this on the rocker/r-devel image, 
which is built on Debian testing/unstable (I had previously been using 
rocker/verse for convenience in installing packages), so that we have a 
more recent BLAS:

BLAS:   /usr/lib/x86_64-linux-gnu/openblas-pthread/libblas.so.3
LAPACK: /usr/lib/x86_64-linux-gnu/openblas-pthread/libopenblasp-r0.3.20.so

   I still fail to reproduce CRAN's problem. I'm not sure whether the R 
version on rocker/r-devel satisfies KH's "a version of R-devel 
configured to use this for the system LAPACK" - it certainly *seems* 
that way but I may be missing something.

   In the meantime,

   * CRAN reverted their platform config so the problem has temporarily 
gone away
   * I added code that I think will avoid this problem to the devel 
version anyway (without having been able to diagnose it in detail)

   cheers
    Ben
