I am trying to get R to use the ACML BLAS, specifically the 'mp' version for multithreading. I have installed acml-4-4-0-gfortran-64bit I added /opt/acml4.4.0/gfortran64_mp/lib to $LD_LIBRARY_PATH. I ran: sudo ./configure --with-blas="-L/opt/acml4.4.0/gfortran64_mp/lib -lacml_mp" At the end of the configuration, the only external library listed is readline, and at the end of my post here is a section of my config.log that shows the problem. Any ideas as t...

Greetings, I have a computer with the following setup: 1)cblfs (pure 64-bit (amd64) linux), kernel2.6.34 gcc4.4.2 2)R-2.11.1 I compiled R with BLAS and lapack using the switched ( --with-blas="- lpthread -latlas -lfptf77blas" --with-lapack="-llapack -lcblas" ). (( http://cran.r-project.org/doc/manuals/R-admin.html#Linear-algebra) ) Prior to compiling R-2.11.1 sh

So, tried again from scratch. Again, CentOS 5.3, which is essentially RHEL 5.3. ./configure --with-blas="-L/opt/acml4.3.0/gfortran64/lib -lacml" In config.log, get things like configure:37199: checking for dgemm_ in -L/opt/acml4.3.0/gfortran64/lib -lacml configure:37230: gcc -std=gnu99 -o conftest -g -O2 -I/usr/local/include -L/usr/local/lib64 conftest.c

Well, CentOS 5.3, which amounts to the same thing. I recently decided to upgrade my main research machine from Fedora Core 8 -> CentOS 5.3. Basically, I was looking to move to a distro with longer 'term-of-life' than the release schedule for Fedora currently allows. The machine is a multi-Opteron box, so both 32- and 64-bit apps natively supported. Since I do a lot of 'linear

Greetings - For a host of reasons I chose (was forced) to upgrade my multi-Opteron box from Fedora 7 -> Fedora 8. In the process, I also updated the ACML I had installed from 4.0.0 to 4.1.0. While I get no errors (that I can find) in the config -> make -> make install sequence, I'm pretty sure (based on some benchmarks) that I'm not getting BLAS and/or Lapack to compile in. So,
