%TOC%

This is a brief Building OSKit Mach HowTO. It covers everything from getting the latest sources of both the [OSKit](http://www.cs.utah.edu/flux/oskit/) and the OSKit branch of the GNUmach kernel. There is also [another guide](http://www.etherhogz.org/doc/oskit-mach.html). Down to building and debugging them. On May 27 after the [[GnuMach]] 1.3 release, Roland McGrath merged OSKit Mach in the [[GnuMach]] 2.x mainline.

First you need to checkout the relevant sources.

### <a name="Accessing_the_FLUX_groups_CVS_or"> </a> Accessing the FLUX groups CVS, or FTP

You can use either the bleeding edge OSKit from CVS, or the latest public release. The latter is preferrable!

CVS:

      CVSROOT=":pserver:anoncvs@leak.cs.utah.edu:/cvs"
      CVS_RSH=ssh
      cvs -z3 co oskit

St. Patricks day 2002 release: <ftp://flux.cs.utah.edu/flux/oskit/oskit-20020317.tar.gz>

Valentine's day 2001 release: <ftp://flux.cs.utah.edu/flux/oskit/oskit-20010214.tar.gz>

### <a name="Accessing_GNU_CVS"> </a> Accessing GNU CVS

Setup your environment with the CVSROOT variable and checkout gnumach.

      CVSROOT=":pserver:anoncvs@anoncvs.gnu.org:/cvsroot/hurd"
      cvs -z3 co -d oskit-mach gnumach

### <a name="OSKit"> </a> OSKit

The attached [[ATTACHURLmodulesx86pc]] file is my personal setup, it works for me. Now, how to configure and build the OSKit.

Configuring:

    # cd oskit-20020317/
    # mkdir build
    # cd build
    # ../configure --prefix=/usr/local --enable-debug

Building:

    # make
    # sudo make install

### <a name="OSKit_Mach"> </a> OSKit Mach

To build any Mach kernel you need an interface generator, a mig. If your host system is Debian based you can get the "Cheap cross-compuler for GNU/Hurd" with a simple:

    $ apt-get gcc-i386-gnu

This will install the i386-gnu-mig in /usr/bin for you.

Configuring:

    # cd oskit-mach
    # mkdir build
    # cd build
    # CFLAGS="-g" MIG=i386-gnu-mig OSKIT_LIBDIR=/usr/local/lib/oskit ../configure --prefix=/gnu --enable-debug

Building:

    # make
    # sudo make install
    # sudo gzip /gnu/boot/oskit-mach
