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.
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.
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.
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
