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

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

Did you ever sort this out and report back to this list (which I may have
missed) ?
