Normally, I do the following to configure R for compilation on my Opteron box with ACML installed: ./configure --with-tcltk --with-blas="-L/opt/acml4.3.0/gfortran64/lib -lacml" However, when I do so, and look at Makeconf, I see BLAS_LIBS = -lblas I thought I would see BLAS_LIBS = -L/opt/acml4.3.0/gfortran64/lib -lacml Why isn't Makeconf picking up the right BLAS_LIBS (or is it? does -lblas mean its finding the right blas?). I tried LD_LIBRARY...

I am encountering segfaults when checking the lme4 package on an Athlon64 system if I use the acml blas. R was built as a 64-bit application using the GCC 4.0.3 compiler suite including gfortran. The version of acml is 3.5.0 gfortran64. I do not encounter the segfaults when I compile R with R's built-in BLAS. The errors occur in the first example in lme4 in a call to lmer. It looks like they would occur in any call to lmer. Running under the debugger shows that the segfault occurs in a call to dtrsm (a level-3 BLAS routine...

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 -L/opt/acml4.3.0/gfortran64/lib -lacml -$ conftest.c: In funct...

...and/or Lapack to compile in. So, either something has changed from 2.6.2 -> 2.7.0, or something has changed from Fedora 7 -> Fedora 8, or both. Here is the sequence I follow to do the config (which seemed to work perfectly before - note: using bash shell): 1. LD_LIBRARY_PATH=/opt/acml4.1.0/gfortran64/lib 2. export LD_LIBRARY_PATH 3. ./configure --with-lapack="-L/usr/lib64" --with-blas="L/opt/acml4.1.0/gfortran64/lib -lacml" However, when I try this, at the end of the config script I'm told Interfaces supported: X11 External libraries: readline Additio...

...n box running Fedora Core 5 with no problems. Had compiled previously with no problems. However, for a variety of reasons (mostly due to ACML upgrade), I tried a recompile using the following sequence of commands (note I'm compiling in ACML support for blas): LD_LIBRARY_PATH=/opt/acml3.6.1/gfortran64/lib export LD_LIBRARY_PATH ./configure --with-lapack --with-blas="-L/opt/acml3.6.0/gfortran64/lib -lacml" This is exactly the same steps I took successfully many times before, but now, when I run the config, it terminates with the following error message: config.status: error: ca...

...pps natively supported. Since I do a lot of 'linear algebra'-heavy things with R, I had compiled R 2.9.0 against the ACML blas. ACML contains lapack, so I killed two birds with one stone. Generally, I would do a configure with ./configure --with-tcltk --with-blas="-L/opt/acml4.3.0/gfortran64/lib -lacml" Worked perfectly. Led to 10-20x speedup in certain calculations. Things haven't been so good since moving to CentOS. The install of the OS went fine, but I can't for the life of me figure out how to compile R against blas - ACML-variety or otherwise. Moreover, putting...

...no and TCLTK_CPPFLAGS='' TCLTK_LIBS='' TCL_CONFIG='' So, it seems as if my self-rolled R isn't TCLTK 'aware'. Is simply adding --with-tcltk to my configure call (i.e., ./configure --with-lapack="-L/usr/lib64" --with-blas="-L/opt/acml4.2.0/gfortran64/lib -lacml" --with-tcltk the solution? I figure worth asking before I literally 'start over'. I see from the manual for linux installs there may be some issues with playing nice if both 32- and 64-bit versions of Tcl/Tk are installed. -------- Original Message -------- Subject:...

...ng to gcc 4.x.x (and, as a consequence gfortran) will cause problems in other areas (but, if other's have done it successfully, with no problems, I'd be willing to try). 2. machine has multiple CPU's (Opteron 880's) - meaning (based on ACML docs), I *should* download and install gfortran64 (which has mp support). However, I don't have gfortran, so...what about 32-bit? Same problem - mp requires gfortran. Hmmm 3. so, download and install gnu64 version of ACML, which is intended for a single processor (ok, so I guess this means I won't be threading jobs over multiple CPU...

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 a...

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
