[R-sig-Debian] 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

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_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 On 09/22/2018 04:55 PM, Dirk Eddelbuettel wrote:> On 22 September 2018 at 16:08, Steve Gutreuter wrote: > | R 3.5.1 is installed under Linux Mint 19 from binaries r-base and > | r-base-dev from ubuntu bionic-cran35.?

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, Steve On 09/23/2018 09:57 AM, Ista Zahn wrote:> On Sat, Sep 22, 2018 at 4:08 PM Steve Gutreuter <sgutreuter at gmail.com> wrote: >> R 3.5.1 is installed under Linux Mint 19 from binaries r-base and >> r-base-dev from ubuntu bionic-cran35.
