## Compiling GNU Mach microkernel

Host development system is IBM T41 running Debian Sarge 3.1r0a GNU/Linux. 

<pre>
gcc version: 3.3.5
GNU sed version: 4.1.2
GNU make version: 3.8
mig version: 1.3-4
</pre>

Obtained gnumach-1-branch sources from cvs:

<pre>
  export CVS_RSH="ssh"
  cvs -z3 -d:ext:anoncvs@ savannah.gnu.org:/cvsroot/hurd co -r gnumach-1-branch gnumach
</pre>

Obtained mig_1.3-4_i386.deb from http://www.hadrons.org/~guillem/debian/pool/main/mig/. Installed it using dpkg:

<pre>
  dpkg -i mig_1.3-4_i386.deb
</pre>

Entered into the gnumach sources and did the following for compilation:

<pre>
   mkdir build
   cd build
   ../configure --host=i386-unknown-gnu0.2 --build=i586-pc-linux-gnu \\
      --enable-kdb --enable-ide 
   make
</pre>   

The kernel file is created in the build directory. Move it to /boot on the testing x86 system Hurd partition. Rename it as gnumach1 and compress it:

<pre>
  mv kernel gnumach1
  gzip gnumach1
</pre>

Add a new entry on the testing machine /boot/grub/menu.lst to boot the new kernel. 

<pre>
  title GNU Hurd K10 Compiled gnumach
  kernel (hd0,3)/boot/gnumach1.gz root=device:hd2s4 -s
  module (hd0,3)/hurd/ext2fs.static--multiboot-command-line=${kernel-command-line} \\
    --host-priv-port=${host-port} --device-master-port=${device-port} \\
    --exec-server-task=${exec-task} -T typed ${root} $(task-create)$(task-resume)
  module (hd0,3)/lib/ld.so.1 /hurd/exec $(exec-task=task-create)
</pre>

Reboot into the new compiled mygnumach1.gz kernel!
