New compilers for Xcode 2.2 (universal gfortran and gcc 4.0.3 for Intel Macs)

I have uploaded a new set of compilers today - the links and details
are on the Wiki:
http://wiki.urbanek.info/index.cgi?TigerGCC

This is the first time gfortran is universal (i.e. runs on both ppc
and i686) and uses Apple's driver, i.e. you can build fat binaries
with it (e.g. -arch ppc -arch ppc64). Intel gfortran target works
only with the gcc 4.0.3 and only on Intel Macs.

My reading of that page implies G77 is no longer needed
(or provided for that matter). Thought CRAN G77 binaries
and GFORTRAN (G95) didn't mix. Is this the
"not yet ready for prime time" developer setup or the new
recommended setup for everyone?

PS. Is there an TrimTheFat script for your universal
compiler for those of us who will not be upgrading anytime
soon?

Paul,

My reading of that page implies G77 is no longer needed (or  
provided for that matter). Thought CRAN G77 binaries and GFORTRAN  
(G95) didn't mix. Is this the "not yet ready for prime time"  
developer setup or the new recommended setup for everyone?

I should have made this more clear: The new compilers are NOT meant  
for the 32-bit ppc CRAN release of R - the supplied G77 is still  
recommended. You cannot mix gcc3 and gcc4 binaries - that didn't  
change. The gfortran is supplied for developers that have to rely on  
gcc4 for one reason or another. Although there are still some issues  
with gcc4, it is the only way to get i686 and 64-bit/G5 ppc builds of  
R on OS X (Apple doesn't ship gcc3 for Intel Macs).

If you are not experimenting with your own builds of R, just ignore it.

PS. Is there an TrimTheFat script for your universal compiler for  
those of us who will not be upgrading anytime soon?

No, but you're free to use lipo to do it if you feel like it.  
However, I wouldn't thin any libraries, because then you won't be  
able to build universal binaries yourself.

Cheers,
Simon
