R SIG Debian - Dec 2006 - Linking Fortran code to BLAS in Ubuntu

Hello!

I have some Fortran code that uses BLAS calls, and would like to compile it
into a shared object to call it from R as per the "Writing R
Extensions"
manual. What needs to go into the "Makevars" file, so that running the
R CMD
SHLIB will work in Ubuntu?

The code compiles properly on the Mac, with the Makevars line
    PKG_CFLAGS=-Wl,-framework -Wl,vecLib
but of course that won't work on Ubuntu :-) . Also, if I need to install any
packages to make the BLAS work, I'd love to know about it.

Thanks!

The preferred way to specify use of the BLAS libraries is with a
Makevars file containing the single line

PKG_LIBS=$(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS)

This will work on Ubuntu and on a Mac. It even works on that other
operating system that many unfortunate souls are forced to use.
