...out compiling, so I would appreciate any help and advice y'all would care to offer. I am trying to compile the 64 bit version of R using a tuned ATLAS and LAPACK (ATLAS 3.9.24). I am running Ubunto 10.04 LTS (through wubi, FWIW). The ATLAS and LAPACK files (atlas.so, f77blas.so, lapack.so, and cblas.so) are sitting in the folder "/usr/local/atlas/lib" (together with the static .a versions and some other files. Following the R installation manual, I used the following configure string: ./configure --enable-R-shlib --enable-BLAS-shlib --with-blas="-L/usr/local/atlas/lib -latlas...

...earched the internet and suspect it has something to do with column major matrix format for Fortran being inconsistent with the row major format for C but I'm not sure how to fix this in C. One suggestion I came across (http://icl.cs.utk.edu/lapack-forum/viewtopic.php?f=2&t=915) is to use cblas_dgemm in which the option 'CblasColMajor' can be specified. However, I would have thought that F77_CALL(dgemm) should work as it has been used in some R packages. I'm also not sure that cblas would work from R. I tried inputting matrices into dgemm as 2 dimensional arrays and as one d...

...an that, BLAS has only one function (xerbla), which takes a string of unspecified length, LAPACK only has four (ilaenv, ilaenv2stage, lsamen, xerbla). The C interfaces to BLAS/LAPACK from Netlib depend on the historic behavior that explicit single-character strings are interoperable, concretely CBLAS and LAPACKE provide C interfaces/code that calls into Fortran BLAS/LAPACK without passing the 1s as lengths of the character strings (functions taking a string of unspecified length are trivial and re-implemented in C). This has been working fine for very many years as the Fortran code never ne...

When building the recent R-devel (a revision slightly before 86534), the compilation stopped when building Rblas with...

Hi, I have tried to pinpoint potential problems which could lead to the LAPACK issues that are currently seen in R. I built the current R trunk using AR=gcc-ar RANLIB=gcc-ranlib ./configure --prefix=$HOME --enable-lto --enable-BLAS-shlib=no --without-recommended-packages and used this to find problem areas. There are quite a few warnings that were flagged, due to mismatches in function

Hi, I have seen a lot of problems from people trying to compile R with MKL. So I am writing my experience in case it helps and to ask one question. I installed R-2.8.1.patched in Ubuntu 9.04 (gcc 4.3.3) using MKL 10.1.1.019. I configured correctly (following MKL userguide) with : sudo ./configure --with-blas="-I/opt/intel/mkl/10.1.1.019/include -L/opt/intel/mkl/10.1.1.019/lib/em64t
