Thank you for your response. I did look in the suggested manual under A.3.1.5
Shared BLAS.
Here are my steps: compiled R using
--with-readline=yes --enable-R-shlib=yes --enable-BLAS-shlib=yes --with-x=yes
--prefix=/usr/local/R-2.11.0
Why do you want shlib support, do you really need it?
For the static case, A.3.1.1 ATLAS described the way to go.
Compiled LAPACK first and then ATLAS using
http://www.scipy.org/Installing_SciPy/Linux#head-89e1f6afaa3314d98a22c79b063cceee2cc6313c
All the .so files have been copied to /usr/lib64
In /usr/local/R-2.11.0/lib64/R/lib, I renamed the .so files for blas and lapack
and linked as
libRblas.so -> /usr/local/lib64/libf77blas.so
libRlapack.so -> /usr/local/lib64/liblapack.so
R does startup OK but when I do the following:
require(nlme)
fm1<- nlme(height ~ SSasymp(age, Asym, R0, lrc), data = Loblolly, fixed = Asym
+ R0 + lrc ~ 1, random = Asym ~ 1, start = c(Asym = 103, R0 = -8.5, lrc = -3.3))
I get
/usr/local/R-2.11.0/lib64/R/bin/exec/R: symbol lookup error:
/usr/local/R-2.11.0/lib64/R/lib/libRblas.so: undefined symbol: ATL_dgemm
This runs just fine without using the .so files which were built with R.
I have never before linked dynamically to ATLAS versions. ATL_dgemm is
probably defined in one of the other libraries. I have not looked since
I currently do not have any ATLAS left on my machines which I was more
used to roughly 3 years ago.

Can you please help? Thanks.

I have built lapack-3.2 and atlas3.8.3 for a RHEL5.3 VM. The following files have been created --
libatlas (.a& .so), libcblas (.a& .so), libf77blas (.a& .so), liblapack (.a&
.so), libptcblas (.a& .so), libptf77blas (.a& .so) and libstatatlas.a.
When building R 2.11.0, I would like to be able to specify --with-blas and
--with-lapack (and not use the ones which come with R). What is the syntax for
that? Which of these libraries should I specify?
Thanks.
