R for Mac OS X

Development Tools and Libraries

This directory contains tools and libraries that are part of the base distribution of R for Mac OS X.

Note: CRAN does not have Mac OS X systems and cannot check these binaries for viruses. Altough we take precautions when assembling binaries, please use the normal precautions with downloaded executables.


gfortran-4.2.3.pkg (OS X 10.5+, signed, 64-bit driver)
MD5-hash: 8783f803038abe6487a362ad5b8995ea
(ca. 27MB)
gfortran-4.2.3.dmg (OS X 10.4, 32-bit driver)
MD5-hash: 9551fc46f55537dd1db581154daf27ef
(ca. 27MB)
Universal GNU Fortran 4.2.3 for Mac OS X 10.4 and higher. It is necessary in order to build R packages from sources that contain Fortran code.

Unlike many other builds, this is a fully universal build of GNU Fortran that uses Apple's driver and supports all target architectures (i386, ppc, x86_64 and ppc64). As such it fully supports compilation into fat files like gfortran -arch i386 -arch ppc -arch x86_64 -arch ppc64 t.f -o t on both Intel Macs and PowerPC Macs (32- and 64-bit). Dependent libraries are fat as well, avoiding problems known from other Fortran builds (such as those from HPC). It installs in /usr/local and comes with an uninstall-script.

Note: more recent Fortran binaries for Xcode are available from Tools page at the R for Mac OS X developer's site.

tcltk-8.5.5-x11.pkg (OS X 10.5+, signed)
MD5-hash: e7c406d91762ffdc4539b23c5b5a3ab4
(ca. 9MB)
tcltk-8.5.5-x11.dmg (OS X 10.4)
MD5-hash: c32dda1b9f2c2776a02cec4e03befc76
(ca. 9MB)
Universal build of Tcl/Tk 8.5.5 for X11 (32-bit and 64-bit). This library is necessary in order to use the tcltk R package (for R 2.8.0 - 2.15.3 only!). It installs in /usr/local. Requires Mac OS X 10.4 (Tiger) or higher for 32-bit R and Mac OS X 10.5 (Leopard) or higher for 64-bit R.

NOTE: R 3.0.0 and higher comes bundled with Tck/Tk 8.6.0 so you do not need this package

For other (optional) 3rd party libraries for development see http://R.research.att.com/libs/. The devpack has been superseded by those libraries. For R you may want to download and install libpng, libjpeg, readline, freetype, fontconfig, pixman and cairo.

Source code for all 3rd party libraries can be found at http://R.research.att.com/src/

You may also want to read the R FAQ and R for Mac OS X FAQ. For discussion of Mac-related topics and reporting Mac-specific bugs, please use the R-SIG-Mac mailing list.

Information, tools and most recent daily builds of the R GUI, R-patched and R-devel can be found at http://R.research.att.com/. Please visit that page especially during beta stages to help us test the Mac OS X binaries before final release! The page also contains links to experimental builds as such 64-bit R for OS X.
