R for Intel 64-bit (Mac Pro) on Mac OS X 10.4 (Tiger)

You can download an experimental build of R 2.5.0 for all four architectures here:
R-25-br-quad.tar.gz (ca. 39MB)
Just unpack to root (e.g. tar fvxz R-25-br-quad.tar.gz -C /), it is a framework that goes to /Library/Frameworks and the 64-bit version is run by R64 instead of R.

Due to high demand here is a step-by-step guide:

• Install Apple Xcode 2.4.1 (or higher) - either download it from Apple or find it on the DVD supplied with your Mac (Xcode 2.3.x or older does NOT work!).
   
• Install GNU Fortran, for example this one: gfortran-4.2.1.dmg (ca. 28MB)
  (I do not recommend Fortran from HPC anymore becasue it is not universal and doesn't support universal builds, see Tools section for details)
   
• Configure R for 64-bit, for example:

  ./configure CC='gcc -arch x86_64' CXX='g++ -arch x86_64' \
  F77='gfortran -arch x86_64' FC='gfortran -arch x86_64' \
  r_arch=x86_64 \
  --with-blas='-framework vecLib' --with-lapack --without-x \
  --with-system-zlib --build=x86_64-apple-darwin8.8.1 \
  --without-readline
  

  Remove the last line if you have 64-bit GNU readline. You don't need the r_arch if you don't plan to use a fat framerwork. Then just make ; make install as usual.

This build is unlike other OS X builds not a framework in order to co-exist with the CRAN binary framework.The following file contains 64-bit build of R 2.3.1 (patched as of 2006/06/27) and it lives in /usr/local/lib64/R with a convenience softlink R64 in /usr/local/bin. It features readline, jpeg and X11 support (if you plan to use the latter you will also need to download the Xorg X11 client below). It passed make check.

curl -O http://r.research.att.com/exp/R-2.3.1-ppc64.tar.gz
sudo tar fvxz R-2.3.1-ppc64.tar.gz -C /
sudo ln -sf /usr/local/lib64/R/bin/R /usr/local/bin/R64

In order to compile packages from sources, you will need gcc 4.0.3 which comes with R 2.3.1 full install or is obtainable separately from the tools section.

Older version: R-2.2.1-ppc64.tar.gz (ca. 16MB)

How to build 64-bit R

In the next step it is recommended to install the 64-bit X11 client (for ppc64 available above - more recent Xorg-based client for both ppc64 and x86_64 will follow soon), such that you will be able to create plots in R. Make sure the client's binaries are first on the PATH, e.g.:

export PATH=/usr/local/lib64/X11/bin:$PATH

Other useful libraries inlcude libpng and libjpeg. There are the corresponding quad-arch binaries:

Armed with gcc, X11 and readline, you can go ahead and get R sources. Apple is kind enough to supply 64-bit vecLib (and it's fast!), so you don't need any other BLAS library. These are the configure flags that were used to build the above experimental binary:

./configure --host=powerpc64-apple-darwin8.7.0 --build=powerpc64-apple-darwin8.7.0 \
--prefix=/usr/local/lib64 'CC=gcc -arch ppc64' 'CXX=g++ -arch ppc64' \
'FC=gfortran -arch ppc64' 'F77=gfortran -arch ppc64' \
'CFLAGS=-g -O3 -mtune=G5 -mcpu=G5' 'FFLAGS=-g -O3 -mtune=G5 -mcpu=G5' \
'LDFLAGS=-arch ppc64 -m64 -L/usr/local/lib' 'CXXFLAGS=-g -O3 -mtune=G5 -mcpu=G5' \
'FCFLAGS=-g -O3 -mtune=G5 -mcpu=G5' --disable-R-framework --enable-R-shlib \
'--with-blas=-framework vecLib' --with-lapack

You can also replace --host and --build with whatever Darwin version you use (see uname -r). The reason for not using config.guess for the platform identification is to force powerpc64 identifier such that it is different from the 32-bit R.
