Compiling and installing kqemu on Ubuntu and Fedora Core 5
==========================================================

Install the dependencies

Ubuntu Breezy 5.10, Debian Sid and Fedora come with gcc 4 by default, but
Qemu will not compile with gcc 4 so we need to install GCC 3.x

Fedora (installed with Software Development option):

  sudo yum -y install compat-gcc-32 texi2html kernel kernel-devel

Now if the kernel was upgraded you might have to reboot.

Ubuntu:

  sudo apt-get install gcc-3.4 g++-3.4 libsdl1.2debian libsdl1.2debian-all
    build-essential libsdl1.2-dev zlib1g-dev checkinstall
    texi2html cvs linux-headers-`uname -r`

Fetch the cvs sources:
  
  cvs -z3 -d:pserver:anonymous@cvs.savannah.nongnu.org:/sources/qemu co qemu
  cd qemu

Configure for Fedora:

  sh ./configure --prefix=/usr --cc=gcc32 --host-cc=gcc32

Configure for Ubuntu:

  sh ./configure --prefix=/usr --cc=gcc-3.4 --host-cc=gcc-3.4

Start building
  
  make

Remove qemu package if it is installed.

  sudo yum remove qemu

or:

  sudo apt-get remove qemu

For fedora, just install it with make install

  sudo make install

For ubuntu, here is a checkinstall commandline which can create a .deb
package on the fly and install that, so that you can deinstall it later
with apt-get.

  sudo checkinstall -y --pkgname=qemu --pkgversion=$(cat VERSION) --pkgrelease=1 \
    --pkglicense=Restricted --pkggroup "Miscellaneous - Text Based" \
    --pkgsource=http://fabrice.bellard.free.fr/qemu/kqemu-1.3.0pre5.tar.gz || exit 18

Now compile the kqemu tarball:

  cd ..
  wget -c "http://fabrice.bellard.free.fr/qemu/kqemu-1.3.0pre5.tar.gz"
  tar xzf kqemu-1.3.0pre5.tar.gz
  cd kqemu-1.3.0pre5 && \
    ./configure && make && sudo make install

Verify everything went by checking whether the module has been installed and is loaded:

  ls -l /lib/modules/`uname -r`/misc/kqemu.ko /dev/kqemu
  sudo modprobe -v kqemu
  lsmod | grep kqemu

Now after each reboot you'll have to perform a few actions before you
can use the kqemu module, such as:

  sudo modprobe -v kqemu
  device="/dev/kqemu"
  rm -f $device
  mknod $device c 250 0
  chmod 666 $device

Place them in a boot script such as /etc/rc.local , modify to suit 
your taste and congratulations!
