Hmm. Interesting. Doing some digging in the build log I encountered
stuff like this:
/usr/local/bin/gfortran -Wall -arch ppc -arch i686 -arch x86_64 -Wall -
undefined dynamic_lookup -bundle build/temp.macosx-10.5-universal-2.6/
fortranobject.o -Lbuild/temp.macosx-10.5-universal-2.6 -lsc_specfun -
lgfortran -o build/lib.macosx-10.5-universal-2.6/special/specfun.so
Looking at the .o's and .so's generated, gcc is definitely generating
ppc64-capable binaries. gfortran (it's the AT&T one to which you
usually point people) *seems* perfectly capable of generating ppc64
binaries (it doesn't complain when run with -arch ppc64).
I've upgraded to the latest gfortran from the AT&T R Tools page and
tried mucking with FFLAGS, F90FLAGS, F77FLAGS, etc. No dice.
Anyone have ideas for anything else I should try?
