If it doesn't tell based on the name, it must look inside the binary. It doesn't look like the sort of thing the linker is checking, but rather something some autoconf script is checking. If we find out what the script actually does, I.e. Look at the generated configure we might figure out what the difference is. > >> Were there any warnings during configure or make? > > I will have to look. > >> Are G5 and G4 cpus compatible? > > Binaries using the G4 instruction set build on a G5 should run on the > G4.
