Thanks to Simon for all the work on the compilers. I can see that the compilers and instructions have been updated on the "tools" page (r.research.att.com/tools). It seems as if the recommended way for us Leopard users is to use gcc 4.2 (Apple Inc. build 5564) for Mac OS X 10.4 (Tiger): (updated 2008/09/16) in order to get a gfortran. Unfortunately, unlike earlier gfortrans, this one also overwrites the Xcode GCC (although it seems as if it is the same exact version) and does not come with a gfortran-uninstall script. Personally I am a bit hesitant to do this, I vastly prefer the old style with a separate gfortran and an uninstall script. Is there any chance we will get this? Or should I be using gfortran 4.2.3 anyway? Small comments on the page 1) the comment on Xcode 3.1 under Leopard CRAN seems a bit odd. When I run the Xcode 3.1 installer I do not really have an option of (de)selecting 4.2 separately. 2) I cannot find the gcc_select script mentioned under alternative compilers in my installation. I know I used to have it under Tiger to switch between gcc 3 and 4, but it is absent on my machine Thanks, Kasper

No, on Leopard you should get the gfortran-4.2 for Leopard. That keeps your Xcode gcc intact. Unfortunately the PackageManager is a bit broken, so the packaged version is still 5531, but there is also a 5564 version based in GNU Fortran 4.2.4 at http://r.research.att.com/gfortran-4.2-5564-darwin9.tar.gz it requires Xcode 3.1 to work. I'm currently building the Leopard release which will include that compiler.

Ok, thanks, point taken, gcc-4.2 is on by default now which I didn't notice.
2) I cannot find the gcc_select script mentioned under alternative compilers in my installation. I know I used to have it under Tiger to switch between gcc 3 and 4, but it is absent on my machine
... in which case you clearly cannot use it ;) That's why I mentioned it as one of the alternatives. It will be present if you installed the 10.3 SDK on Leopard and it works just fine with gcc-4.2. Cheers, Simon
Dear Simon, If I understand you correctly, this means that leopard users wanting to compile R themselves either a) stick with the pre-leopard instructions (Xcode 2.4 based) or b) somehow (how?) obtain the 10.3 SDK so as to have the convenience of the gcc_select script or c) symlink to the gcc 4.2 binaries (how?) Thank you very much for all your efforts for the Mac R community, it is just that for some months now (since Xcode 3.1 was released) that I would like to try the new gcc for building R, but I am stuck with 4.0.1 kind regards, Ivan
