This looks as if you are building OpenBLAS as a /dynamic/ library installed in your package directory. This cannot work since the run-time linker will not search your package directory for dynamic libraries. You could build OpenBLAS as a /static/ library instead. However, I am unsure why you want to build OpenBLAS in the first place, since any R package can reliably link with the BLAS and LAPACK versions used by R. See WRE on Makevars, BLAS_LIBS etc. for details. cheerio ralf ______________________________________________ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel
