My belief is that if you

- build a single-architecture R from the sources
- use that to test your packages

it should work.  If that is not an option, you can try
R CMD INSTALL --no-multiarch
with the CRAN build of R (and if that works try
R CMD check --install-args=--no-multiarch
).

(As someone who has never had a PPC Mac this is extrapolation from what I do when I want to build/test one of i386/x86_64, possibly with R --arch=x86_64.)

Should have made it clear that I want to compile
packages (which include C/C++) for testing before
putting on CRAN, and I don't have an intel
machine available.

FAQ 5.3 seems to suggest I use XCode  >=2.4.0 (I have 3.0 installed).
FAQ 5.4 doesn't apply because it  needs  an intel  computer.

sorry for not being clear first time

Hi

I have a little powerPC G4 powerbook,  running macosx10.5.8.

I don't think XCode 3.2.1 will work for me.

What are my options?

thanks in advance

Robin
