openblas
(CCing the R-devel list, maybe someone will have a better answer.) To be honest, I don't know how to. I wasn't able to configure R to use OpenBLAS using the configure script and options on my Linux Fedora system. I configure it without external BLAS, then replace the libRblas.dylib (.so in my case) with a link to the OpenBLAS dynamic link library. Peter

thanks Peter, I appreciate your advice here. ./configure --with-blas="-lopenblas" --without-recommended-packages gives me Interfaces supported: X11, aqua, tcltk External libraries: readline, curl Additional capabilities: JPEG, NLS, ICU Options enabled: shared BLAS, R profiling Capabilities skipped: PNG, TIFF, cairo Options not enabled: memory profiling Recommended packages: no so it doesn't look like it's using the openBlas... how come the arguments to ./configure are being ignored? <hankin.robin at gmail.com> hankin.robin at gmail.com <hankin.robin at gmail.com> <hankin.robin at gmail.com> On Wed, May 8, 2019 at 1:04 PM Peter Langfelder < peter.langfelder at gmail.com> wrote:
I'm a linux guy so take the advice with a grain of salt... When you run the configure script, look at the output at the end of the run, it should either say Options enabled: shared BLAS, ... (means you are using R BLAS) or it should mention OpenBLAS in External libraries (meaning you are using OpenBLAS). You can also see the results in config.log of you search for BLAS. Or you could use the old trick of replacing libRblas.dylib with a link to the appropriate OpenBLAS dylib. On Tue, May 7, 2019 at 5:01 PM robin hankin <hankin.robin at gmail.com> wrote:
Hello, macosx 10.13.6, Rdevel r76458 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 cannot reproduce the error. Can anyone advise? hankin.robin at gmail.com
