openblas
...I'm trying to compile against openblas to reproduce an error on the
CRAN check page (my package is clean under winbuilder and all but one
of the checks). I've downloaded and installed openblas 0.3.7 but I
am not 100% sure that it is being used by R.
Using
./configure --with-blas="-lopenblas"
Then running R to discover the PID I get:
Rd % lsof -p 17960|egrep -i blas
R 17960 rhankin txt REG 1,8 189224 33471762
/Users/rhankin/Rd/lib/R/lib/libRblas.dylib
But it is not clear to me how to interpret this. Am I using openblas
as intended? I suspect not, for I can...

...external BLAS, then replace the libRblas.dylib (.so
in my case) with a link to the OpenBLAS dynamic link library.

Compiling R on Fedora with threaded openblas
...nstall the library, you can run "make
PREFIX=/path/to/your/installation install".
which suggests to me I successfully built a multi threaded openblas.
Whilst trying to build against Fedora's openblas I used the following
configure option
BLAS_LIBS="-L/usr/include/openblas -lopenblas"
or
BLAS_LIBS="-L/usr/lib64 -lopenblas"
and
./configure --with-blas --enable-R-shlib --enable-BLAS-shlib
Whilst trying to swap out the default libRblas.so I built simply with
./configure --enable-R-shlib --enable-BLAS-shlib
then I symlinked my locally built libopen...

Change between 86152 and 86534 - probably 86265 - that looks for zspmv in BLAS and not LAPACK causes R with OpenBLAS to fail

Error when compiling R with openblas
Hi,
I tried to compile R with openblas on a ubuntu 12.04 machine. I have to
say that I normally use the package system and that I have no experience
with compiling R.
I did the following:
./configure --enable-BLAS-shlib --enable-R-shlib LIBnn=lib
--with-blas="-L/usr/lib/openblas-base/ -lopenblas"
--enable-memory-profiling --with-x=yes
go the output:
R is now configured for x86_64-unknown-linux-gnu
Source directory: .
Installation directory: /usr/local
C compiler: gcc -std=gnu99 -g -O2

custom built R will not change BLAS/LAPACK with update-alternatives
...d no openblas in any line.
7. sessionInfo shows it is using OpenBLAS
Matrix products: default
BLAS/LAPACK: /usr/lib/x86_64-linux-gnu/openblas-openmp/libopenblasp-r0.3.25.so; LAPACK version 3.11.0
8. R CMD config shows difference in the configuration
- My build:
./R CMD config BLAS_LIBS: -lopenblas
- ./R CMD config LAPACK_LIBS: nothing
- Debian's R
