Just for fun, I decided to see if I could build it from source. I ran into only one hiccup, related to gfortran. The gfortran compiler is a new one I got the other day to build Julia.
> gfortran -v .. Target: x86_64-apple-darwin11 .. gcc version 4.6.2 20111019 (prerelease) (GCC) |
Here are the build instructions for R:
# download R curl -O http://cran.r-project.org/src/base/R-2/R-2.15.0.tar.gz # unpack R tar fxz R-2.15.0.tar.gz # choose the architecture (x86_64, i386, ppc or ppc64) arch=x86_64 # create a build directory mkdir R-$arch cd R-$arch # configure R ../R-2.15.0/configure r_arch=$arch CC="gcc -arch $arch" \ CXX="g++ -arch $arch" F77="gfortran -arch $arch" \ FC="gfortran -arch $arch" OBJC="gcc -arch $arch" \ --x-includes=/usr/X11/include --x-libraries=/usr/X11/lib \ --with-blas='-framework vecLib' --with-lapack # build R make -j8 # At this point you can run R as `bin/R' even without installing # install R make install # in some cases you may need to use ``sudo make install'' instead |
The configure step fails with a complaint about the options to gfortran. The config.log file reads:
.. configure:7007: result: defining F77 to be gfortran -arch x86_64 configure:7179: checking for Fortran 77 compiler version configure:7188: gfortran -arch x86_64 --version >&5 GNU Fortran (GCC) 4.6.2 20111019 (prerelease) Copyright (C) 2011 Free Software Foundation, Inc.

Removing
"-arch $arch" from F77 and FC above, fixed it. R builds pretty quickly, then this works:
I don't have any real reason to do this, just thought I'd try it. Also, an important question is whether shared libraries like
/usr/X11/lib/libpng.dylib are linked in properly. This works (but I'm not sure where it's getting libpng from):> png('~/Desktop/x.png')
> plot(1:10)
> dev.off()
