How can I do that? Just trying to pass arch flags in CFLAGS/LDFLAGS is not working:% make make all-recursive Making all in libusb CC libusb_1_0_la-core.lo llvm-gcc-4.2: -E, -S, -save-temps and -M options are not allowed with multiple -arch flags It does not help that the full command-line isn't displayed (how can I see that instead of the fake command lines here, by the way)... And I looked in configure --help for anything mentioning universal or arch and did not see anything. I'd rather not have to build twice and lipo everything together, and also am not sure what would then happen to the *.la etc. files that only knew about one arch. YA

Add an "LDFLAGS='-Wl,- force_cpusubtype_ALL'" if you want to force the ppc subtype to be CPU_SUBTYPE_POWERPC_ALL instead.
