The advice _is_ in the R-admin manual which the INSTALL file asks you to
read if you have any questions. It covers using enhanced BLAS libraries.
R builds out of the box on FC3, FC4 and Suse on AMD64. I use Goto's BLAS,
but ATLAS can be used (except that building a shared version is tricky).
Incidentally, I have just tried building R on a Fujitsu Amilo amd64 with
debian-amd64 (unstable) and ATLAS. Both 'make' and 'make check' worked
without complaints with gcc-3.4.5,
There is no gcc 3.4.5! There are versions 3.3.5 and 3.4.4.
but when I tried gcc-4.0.1, 'make check' failed with a segmentation
error after
I have seen this on FC3. Note that ZAXPY is a BLAS routine, and you are
using ATLAS: was that also built with gcc-4.0.1? On FC3 I get the failure
if I use its BLAS, and not if I configure R with --without-blas. (I did
not see the problem using the gcc4 RPM from FC3 update, and I gather
others have managed to use gcc4 from FC4.)
We do not recommend gcc-4.0.x as yet: we have yet to see any performance
gains (only losses) from it, and this is one of a number of known
nuisances. More serious are places where it apparently generates
incorrect code and so gives incorrect answers.
