# Nothing below this line should need editting.

# This script installs the ViaVoice rpms, as released originally by IBM,
#
# ViaVoice_runtime-3.0-1.2.i386.rpm		The runtime package.
# ViaVoice_TTS_rtk-5.1-1.2.i386.rpm		The Text To Speech runtime kit.
# ViaVoice_Dictation-1.0-1.0.i386.rpm		The dictation application.
# dict.lic.ila.txt				The overall license file.
#
# ViaVoice is no longer maintained by IBM.  It seems that you even cannot buy
# it anymore!  The older rpms listed above are based on, developed on and
# tested on redhat 6.2 using the blackdown jdk-1.2.2-RC4 java version.
# On more modern systems, like systems that are based on glibc-2.3 (ie RH9)
# these rpms will not work at all anymore.  It is needed to link them with
# an older glibc.
#
# This script installs the ViaVoice rpms as normal, but installs the original
# RedHat 6.2 files and the blackdown java in a special directory (INSTALLDIR).
# The ViaVoice start-scripts are then patched to use this environment.  The
# RedHat 6.2 rpms that are installed are not installed as rpms (you won't see
# them back with rpm -qa) and can be easily gotten rid of by just removing
# the whole directory (INSTALLDIR).
# The files in INSTALLDIR are also patched, most notably because they
# contain two hardcoded paths to files: the dynamic linker and the
# Bourne shell (/bin/sh).  Because we have to change the binaries, there
# is no space to make these paths longer than they already are.  Therefore
# they are changed into '/tmp/ld-vvlnx.so.2' and '/tmp/vv' respectively,
# having the same original length.  Those two are then set to be symbolic
# links to the real dynamic linker and shell to be used.
# Note that ALSA (Advanced Linux Sound Architecture), the sound drivers that
# replace the older OSS as of kernel 2.5, also introduce a problem for some
# soundcards: unlike the OSS drivers, the ALSA drivers limit the recording
# buffer to the hardware limit of your sound card.  For example, the SB Live!
# only has two 'period' buffers (called fragments before), and although
# viavoice requests an 'arbitrary number of periods, size 1024 bytes', it
# only gets two periods of 1024 bytes: 2048 bytes in total!  The ViaVoice
# engine however doesn't even process sound until it sees at least 6102 bytes.
# The 'solution' for this is to increase the buffer size (from 1024 to say
# 8192), this script also takes care of that.  Unfortunately, also that is
# possibly not enough: the sound is read from the hardware in chunks of
# 'period size' and having only two buffers this is often causing an underrun.
# When ALSA sees an underrun... it stops the sound stream.
# While this script works for me - you might still run into this problem.
# The problem can easily be detected by attaching the ViaVoice 'engine'
# with 'strace' once it runs and see if it reads the dsp device or not,
# or that all it does is calling ioctl without ever trying to read(2)
# something.  I reported this difference between OSS and ALSA's OSS emulation
# to the ALSA developers and they 'fixed' it in the current CVS of ALSA
# (should be fixed in 0.9.6).  But... you guess it, it still doesn't work.
# At the moment I am working on a real solution for ALSA which will be used
# by 'vvinstall2'; this script will be for the newer ViaVoice rpms that came
# with the 'mandrake 8.0 power edition' however.
#

# This script needs the following rpms to be installed:

# Using RedHat 9:
#
# rpm-4.2-1.i386.rpm
# bash-2.05b-20.i386.rpm
# grep-2.5.1-7.i386.rpm
# which-2.14-5.i386.rpm
# sed-4.0.5-1.i386.rpm
# tar-1.13.25-11.i386.rpm
# sudo-1.6.6-3.i386.rpm
# ncftp-3.1.5-4.i386.rpm
# cpio-2.5-3.i386.rpm
# vim-common-6.1-29.i386.rpm
# coreutils-4.5.3-19.i386.rpm (for mv, rm, cp, chmod, cat, id, ln,
#                                  pwd, md5sum, wc, tee and install).

# Using RedHat 8.0:
#
# Same rpms, different versions; except
# that instead of coreutils- you will have
#
# fileutils-4.1.9-11.i386.rpm (for mv, rm, cp, chmod, ln and install).
# textutils-2.0.21-5.i386.rpm (for cat, md5sum and wc).
# sh-utils-2.0.12-3.i386.rpm (for id, pwd and tee).

# Mandrake and other versions of RedHat:
#
# Actually, the versions of these rpms are not important.
# Just run the script and it will tell you if anything is
# missing.
