After re-reading appendix A2.2, I still don't see what I am doing wrong. The comments in config.site say ## Use LAPACK_LIBS for all '-L' and '-l' options needed for linking ## against an external LAPACK implementation. ## Note that (see R-admin) that our main intention is to allow a ## LAPACK-containing BLAS to be used, so this is rarely needed, and ## it is not used if the BLAS already contains LAPACK. so I don't need to set LAPACK_LIBS as the acml BLAS already contains LAPACK? > I am a bit puzzled: currently ACML is only available for Linux, Solaris > and Windows, so where did you find a FreeBSD version? I didn't; but see http://lists.freebsd.org/pipermail/freebsd-amd64/2005-September/006043.html > Apparently libRlapack.so.

Ah, when I tried R-rc, I found what I was doing wrong: the copy of R in /usr/local/bin/R was not updated from R_HOME/bin/R For R-rc with the same two changes in config.site, the build passes make check (except for internet.R as I am behind a firewall and set http_proxy in .Renviron which appears to be ignored by make check). But in lib/ I now have erdos# ls -l /usr/local/R-rc/lib/ total 2112 -rwxr-xr-x 1 root 506 289732 Sep 29 07:52 libRblas.so* -rwxr-xr-x 1 root 506 1831697 Sep 29 07:57 libRlapack.so* Does this mean that the acml BLAS is not being used? > version _ platform x86_64-unknown-freebsd6.1 arch x86_64 os freebsd6.1 system x86_64, freebsd6.1 status RC major 2 minor 4.0 year 2006 month 09 day 27 svn rev 39543 language R version.string R version 2.4.0 RC (2006-09-27 r39543) h. -- ---------------------------------- Hiroyuki Kawakatsu Business School Dublin City University Dublin 9, Ireland Tel +353 (0)1 700 7496 ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
