Welcome. + +GNU Mach is the microkernel upon which a GNU Hurd system is based. It +provides an Inter Process Communication (IPC) mechanism that the Hurd +uses to define interfaces for implementing in a distributed multi-server +fashion the services a traditional operating system kernel provides. + +GNU Mach runs on 32-bit x86 machines. A version running on 64-bit x86 +(x86_64) machines is in progress. Volunteers interested in ports to +other architectures are sought; please contact us (see below) if you'd +like to help. + +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 Mach Interface Generator (MIG) is no longer part of this distribution, and +instead is packaged separately: GNU MIG. + +Generic installation instructions may be found in the file INSTALL. + +By default, most drivers for network boards are included, as well as +drivers for IDE, SCSI and AHCI disks. + +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 by default +because it adds considerably to the unpageable memory footprint of the +kernel. + +GNU Mach can be cross-built. No specific options need to be given when +building on a 32-bit x86 ELF userland such as GNU/Linux. Manually switch the +compiler to 32-bit mode when using a 64-bit x86 (x86_64) ELF toolchain: + + $ [...]/configure --host=i686-gnu CC='gcc -m32' LD='ld -melf_i386' + +or point to a 32-bit ELF toolchain: + + $ [...]/configure --host=i686-gnu CC=i686-linux-gnu-gcc LD=i686-linux-gnu-ld + +Also, GNU MIG needs to be a 32bit version to properly compile the interfaces, +you can specify for instance + + $ [...]/configure --host=i686-gnu CC=i686-linux-gnu-gcc LD=i686-linux-gnu-ld MIG=i686-linux-gnu-mig + + +Please read the FAQ at . +Bug reports should be sent to or filed on +. Requests for assistance +should be sent to or filed on +. You can also find us on +the Freenode IRC network in the #hurd channel. -- cgit v1.2.1
