R SIG Debian - Sep 2018 - libRblas.so: cannot open shared object file: No such file or directory

R 3.5.1 is installed under Linux Mint 19 from binaries r-base and 
r-base-dev from ubuntu bionic-cran35.? Mysteriously, packages using 
libRblas cannot be compiled.? I get: libRblas.so: cannot open shared 
object file: No such file or directory.? And indeed, I find no libRblas.so.

Any ideas about how to fix this?

Thanks,

Steve

What does   sessionInfo()   show?  For me on this computer it is

  R> sessionInfo()
  R version 3.5.1 (2018-07-02)
  Platform: x86_64-pc-linux-gnu (64-bit)
  Running under: Ubuntu 18.04.1 LTS

  Matrix products: default
  BLAS: /usr/lib/x86_64-linux-gnu/openblas/libblas.so.3
  LAPACK: /usr/lib/x86_64-linux-gnu/libopenblasp-r0.2.20.so
  [...]


If Mint follows the setup I use for the Debian package, then you _never have
libRblas.so_ because we use the _external_ BLAS.  This allows you to switch
to Atlas (tuned BLAS), OpenBLAS (multithreaded), Intel MKL (multithreaded and
possibly a little faster than OpenBLAS but much bigger), ...

Thanks Dirk.? That is what I thought, and sessionInfo() returns:

Matrix products: default
BLAS: /usr/lib/x86_64-linux-gnu/atlas/libblas.so.3.10.3
LAPACK: /usr/lib/x86_64-linux-gnu/atlas/liblapack.so.3.10.3

locale:
 ?[1] LC_CTYPE=en_US.UTF-8?????? LC_NUMERIC=C
 ?[3] LC_TIME=en_US.UTF-8??????? LC_COLLATE=en_US.UTF-8
 ?[5] LC_MONETARY=en_US.UTF-8??? LC_MESSAGES=en_US.UTF-8
 ?[7] LC_PAPER=en_US.UTF-8?????? LC_NAME=C
 ?[9] LC_ADDRESS=C?????????????? LC_TELEPHONE=C
[11] LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=C

so R is indeed aware of a blas.? However, packages that require a blas 
fail to build and return

libRblas.so: cannot open shared object file: No such file or directory

Baffled,

Steve

Can you show use an example? That is, what code did you run exactly,
and what was the error, exactly?

For example,

install.packages("emplik")

is failing with: libRblas.so: cannot open shared object file: No such 
file or directory

As Dirk pointed out, this is likely an error in the emplik package,
