There is a specific section on using ACML, via command-line flags. One point is that you want the path as part of BLAS_LIBS, not for all compilation. > After re-reading appendix A2.2, I still don't see what I am doing > wrong.

You really do need to study the manual section on BLASes, as that suggests a different (and more efficient) way of doing this. > >> 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 > -- Brian D.
