Camstream

I had trouble getting camstream to compile on my computer - it complained that it couldn't find qt, or that it wasn't multi-threaded.

First, you need to install the multi-threaded version of qt.

apt-get install libqt-mt

apt-get install libqt-mt-dev

Qt is not multithreaded (or its name is wrong). You MUST have a multithreaded
version of the Qt library installed or CamStream will simply not compile.

You need to set the environment variable QTDIR to the correct place.

export QTDIR=/usr/share/qt3

The actual directory you need to use may vary from the above.  Type locate qt3 to try to find it.

If this command complains that the database isn't up to date you can do updatedb.

Of if this still doesn't work try something like:
find / -iname "qt3"

You need to find a directory called qt3.

checking location of Qt library...

If this comes up after you've fixed the multi-threaded issue it's possible that you set the wrong location for QTDIR.
