-*- Text -*- This is the GNU Mach 1.2 distribution. This kernel is derived from the Utah kernel source. We use it to run the Hurd on. It is being distributed by us so that we can more easily modify the source, and so that it will work with the normal GNU coding standards and Makefile conventions. libmach, bootloaders, default pagers, and the like are not part of this distribution. For libraries, we refer you to the GNU C library, which has Mach support. For bootloaders, we refer you to GRUB. (This kernel can be loaded by any bootloader that uses the multiboot standard.) For default pagers, we refer you to your particular system that you will run on top of Mach. The interface generator `MiG' is no longer part of this distribution. Generic installation instructions may be found in the file INSTALL. By default, you get a kernel with no device drivers for network devices, because the Hurd has its own drivers running in userland. Drivers for IDE and AHCI disks are however included by default. If you want the in-kernel debugger compiled in, specify --enable-kdb to configure. This is only useful if you actually anticipate debugging the kernel, of course. We don't turn it on be default because it adds considerably to the unpageable memory footprint of the kernel. The specific switches you give to configure are always recorded in the file `config.status'. So you can always tell what options you used to build a particular kernel. The gnumach kernel can be cross-built. No specific options need to be given when building from a 32bit x86 ELF userland such as Linux. When running on a 64bit x86 ELF userland, one has to specify cross-compilation variables, typically: export CPP='gcc -m32 -E -x c -undef -ansi' export CC='gcc -m32' export LD='ld -melf_i386' and give the --host=i686-unknown-gnu option to ./configure Bug reports relating to this distribution should be sent to bug-hurd@gnu.org. Requests for assistance should be made on help-hurd@gnu.org.
