According to WRE [1] you should include "$(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS)" in PKG_LIBS via src/Makevars. You can access these values also via R CMD config LAPACK_LIBS etc. You cannot assume to have CBLAS installed.

I tried to use > pkg-config but it doesn't work with CRAN servers, any alternatives? You mean pkg-config does not work or does not find OpenBLAS? The latter would be hardly surprising, since the CRAN machines most likely use the (partial) reference BLAS/LAPACK that is included with R. Why should they have OpenBLAS installed as well? cheerio ralf ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
