A potentially confusing point is that the code for OSKit/Mach (as opposed to the 1.X release, aka "GNU Mach") is now on the `TRUNK` of the 'gnumach' CVS module. In the past the trunk was 1.X (GNU Mach) and 2.0 (OSKit/Mach) was a branch. + + $ cvs -z3 -d:ext:anoncvs@savannah.nongnu.org:/cvsroot/hurd co gnumach + +In case you have been tracking the oskit-branch and want to move to the current `HEAD` branch you can issue the following instead to update your tree. + + $ cd <YOUR MACH DIR> + $ cvs -z3 -d:ext:anoncvs@savannah.nongnu.org:/cvsroot/hurd update -Pd -A + +Where `<YOUR MACH DIR>` can be `gnumach`, `oskit-mach`, or similar. The `-A` is what moves you from a branch to the default (in this case HEAD), but without forcing a specific tag. `-P` Prunes your local copy from stale directories and `-d` creates new directories for you. + +**_The Hurd servers:_** + +In case you want to build the Hurd servers as well, you can check them out with: + + $ cvs -z3 -d:ext:anoncvs@savannah.nongnu.org:/cvsroot/hurd co hurd + +**_Inteface generator:_** + +See the [[microkernel/mach/MIG]] for more information. + +Check it out using + + $ cvs -z3 -d:ext:anoncvs@savannah.nongnu.org:/cvsroot/hurd co mig + +## <a name="Building"> Building </a> + +The recommended versions of GCC are + +<dl> + <dt> For the OSKit</dt> + <dd> GCC 2.95.X </dd> + <dt> For GNUmach and <nop>MiG</nop></dt> + <dd> GCC 3.2 </dd> +</dl> + +### <a name="The_OSKit"> </a> The OSKit + +Do _not_ forget to apply all known [[OskitPatches]] before starting the build!

The patch is in this [message](http://mail.gnu.org/archive/html/bug-hurd/2003-06/msg00054.html) in the bug-hurd mailing list. + +### <a name="Mach_Interface_Generator"> Mach Interface Generator </a> + +To build any Mach kernel you need an interface generator, MiG. To be on the safe side, use the CVS version. If you use Debian, you can install package [mig-i386-gnu](http://packages.debian.org/mig-i386-gnu). If you don't use Debian or want to compile MiG by yourself on Linux/\*BSD system, you must first install Mach headers. In Mach directory do: + + $ mkdir build + $ cd build + $ ../configure --prefix=/usr/local # Default prefix is / ! + $ sudo make -k install-headers # -k is for ignoring errors + +Now you are ready to compile and install MiG (commands are in Mig's source directory): + + $ automake --add-missing # sometimes it's needed + $ mkdir build + $ cd build + $ ../configure + $ make + $ sudo make install + +### <a name="GNUmach_2_0_OSKit_Mach_"> </a> GNUmach 2.0 (OSKit-Mach) + +Unlike its half sister, the OSKit-Mach kernel does _not_ need a cross compiler. The regular gcc for your x86 Linux system does just fine. However, you might want to use gcc 3.2 with the latest and greatest CVS version of Mach. + +**_Configuring:_** + + $ cd gnumach + $ mkdir build + $ cd build + $ MIG=/usr/local/bin/mig \ + CC=gcc-3.2 \ + CFLAGS="-g -O2" \ + OSKIT_LIBDIR=/usr/local/lib/oskit \ + ../configure --prefix=/gnu + +Comment: Barry deFreese + +I updated `CFLAGS` to `CFLAGS="-g -O2"`. Using just `-O` I was getting errors in the `machine_init` function. For newbies like me, the `-g` is only needed if you want to enable debugging. The `-O2` is Oh 2, not Zero 2. + +**_Building:_** + +Instead of using `make kernel` to build kernel, in OSKit-Mach you have to use <code>make kernel-<var>DRIVERS</var></code>, where <var>DRIVERS</var> is <code><var>DRIVER</var>+<var>DRIVER</var>+...+<var>DRIVER</var></code> (a list of drivers separated by `+`). <var>DRIVER</var> can be one of: + +* `ide` +* `floppy` +* <code>ethernet\_<var>ETHDRV</var></code> where <var>ETHDRV</var> is taken from `oskit/oskit/dev/linux_ethernet.h`. +* <code>scsi\_<var>SCSIDRV</var></code> where <var>SCSIDRV</var> is taken from `oskit/oskit/dev/linux_scsi.h`. + +Thus, to build a IDE capable kernel with 3Com Vortex Boomerang support you use the following: + + $ make kernel-ide+ethernet_vortex + $ sudo make install + $ sudo gzip -f /gnu/boot/oskit-mach + +If the `make` command complains about missing dependencies, then you haven't passed correct `OSKIT_LIBDIR` variable to the `configure` script. Or you can use the patch below and pass something like `--with-oskit=/usr/local` to `configure`. + +Comment: Barry deFreese + +If you receive an error like `No rule to make target Kernel-ide...`, there is a patch for an issue with finding the oskit libraries. Then run `configure` on gnumach again with the option `--with-oskit=/path/to/oskit/libraries`. + +The patch can be found here: [gnumach-oskit-path.patch](http://www.vis.ethz.ch/~wagi/hurd/gnumach/gnumach-oskit-path.patch) Thanks wagi!! + +Don't use both `--with-oskit` and `OSKIT_LIBDIR`. Choose one of these methods. + +If you want to use tftp to download the kernel from Grub and don't care about the symbols I recommend either stripping or removing the `--enable-debug` and `-g` statements. + +## <a name="Debugging"> Debugging </a> + +See the [[Mach/RemoteDebugOskitMach]] page. + +## <a name="Attachments"> Attachments </a> + +* [[ATTACHURLmodulesx86pc]]: Configures modules to build in OSKit. +> Compared to 21May04 CVS, this adds SMP but omits the random module which was added to CVS in Jan03. + +* [[ATTACHURLmodules-lightx86pc]]: Lighter version of required modules.
