2. Installation

2.1 How to obtain QSSTV

The latest release and snapshots can be found at:

2.2 Requirements

QSSTV version 6.0a has been tested with Qt-3.3, At this moment it still lacks the FAX support. It will be available in the next (sub)version.

2.3 Compilation and installation

There are different ways to install QSSTV on your system. Should you run into problems please report them to the the author at on4qz@telenet.be

Using qsstv-x.xx.tgz

% tar -xvzf qsstv-x.xx.tgz
% cd qsstv-x.xx
% qmake qsstv.pro
% make
% su
% make install

Make sure that the QTDIR environment is set and points to the correct basedirectory. (e.g. QTDIR=/usr/lib/qt3).

Using qsstv-x.xx.src.rpm

Install the src rpm package and then rebuild the binary files.

% su
% rpmbuild --recompile  qsstv-x.xx.src.rpm

Make sure that the QTDIR environment is set and points to the correct basedirectory. (e.g. QTDIR=/usr/lib/qt3).

Using qsstv-x.xx.i586.rpm

Simply install it as any other rpm.

2.4 Testing the Soundcard

An easy way to detect if the soundcard setup is working for QSSTV, is to execute the following commands.

#cdplay
#dd bs=8k count=5 < /dev/dsp > music.au
 5+0 records in
 5+0 records out
#cat music.au >/dev/dsp

The command cdplay starts the cdplayer(so be sure to have an audio cd inserted). You can also generate an other external audio signal through the Line Input connector.

The copy command (dd) takes the input from the /dev/dsp interface (for 5 seconds) and redirects it to the music.au file. You replay the sound with the cat command. This test comes in very handy to detect access problems (permission denied ...) on the interfaces. Be sure to have the correct permissions for the /dev/dsp file (normally a softlink to /dev/dsp0). You need read/write access. Do not forget to use a mixer device to select the recording source and to adjust input and output levels.

Sometimes applications such as amaroK or other mediaplayers are started automatically, blocking the access to the dsp interfaces. Make sure that you quit these applications before starting QSTTV.
