38This are notes of how to perform the test.
39
40First of all you will need a i386 jail on amd64. This could be build like
41this:
42
43cat > jailbuild.sh <<EOF
44#!/bin/sh
45
46jail=/var/tmp/jail2 # Change this
47
48mount | grep $jail | grep -q devfs && umount $jail/dev
49
50here=`pwd`
51chflags -R 0 $jail
52rm -rf $jail
53mkdir -p $jail
54
55cd /var/tmp/deviant2 # You will need to change this!
56make -j4 TARGET=i386 TARGET_ARCH=i386 DESTDIR=$jail world
57make     TARGET=i386 TARGET_ARCH=i386 DESTDIR=$jail distribution
58
59mount -t devfs devfs $jail/dev
60
61cp /etc/fstab /etc/hosts /etc/resolv.conf $jail/etc
62cp /boot/kernel/kernel $jail/boot/kernel
63EOF
64
65Before changing to the jail you may need these files:
66- Fetch the Firefox i386 installer. (http://www.mozilla.com)
67- Fetch a clip for a win32 codec:
68  ftp http://www.jhepple.com/support/SampleMovies/Real_Media.rm
69
70and place these in for examle $jail/root
71
72Chroot to /var/tmp/jail /bin/sh
73
741) Install wine. For example by "UNAME_m=i386 pkg_add -r wine"
753) Run wine on the Firefox installer.
76
77The mplayer test:
78
79It would seem that the default build of mplayer does not contain
80the i386 codec, so you have to build mplayer your self with option
81"Enable win32 codec set on the IA32 arch".
82Remember to set the environment variable UNAME_m to "i386".
83
84cat > mplayer.sh <<EOF
85#!/bin/sh
86
87export DISPLAY=<your display host goes here>:0
88while true;do
89	pos=100
90	for i in `jot 5`; do
91		mplayer -vc rv40win -geometry $pos:$pos /root/samples/Real_Media.rm < \
92			/dev/null > /dev/null 2>&1 &
93		pos=$((pos + 50))
94	done
95	for i in `jot 5`; do
96		wait
97	done
98done
99EOF
