A definitive yesno. As far as it comes to GNU Mach, it is a statically linked ELF object started by GRUB. The build requires some functions to come from libc.a (strcpy, and such stuff). But those are not system-specific (only processor specific). Thus you can build it on any GNU system with the same CPU. The Hurd is quite different (as well as any other application). We definitely do use the same object format. We use the same toolchain. So all the ld, as, gcc, etc, are directly usable. Still, we use different headers, libraries, and link programs slightly differently. Look into the make-cross script to figure out how to set up a light cross compiler (it's really only a specs file for gcc and a wrapper script). Thanks, Marcus -- `Rhubarb is no Egyptian god.'
