INSTALL file for vlc, the VideoLAN Client
Building VideoLAN
=================
A typical way to configure the vlc is :
./configure --prefix=/usr --enable-ppro --enable-mmx --enable-gnome
See `./configure --help' for more information.
Then, run `make', and `make install' to install it.
To build a Debian package, you may use :
dpkg-buildpackage -rfakeroot -us -uc
To build RedHat packages, use :
rpm -ba vlc.spec
Installing and running VideoLAN
===============================
You can install the vlc and its plugins by typing :
make install
But you don't need to do it if you don't want ; vlc can be launched
from the current directory as well :
./vlc

Troubleshooting
===============
A mailing-list has been set up for support and discussion about the
vlc. Its address is :
<vlc@videolan.org>
To subscribe, send a mail to <listar@videolan.org> with the following
words in the mail body :
subscribe vlc
To unsubscribe, do the same with the words :
unsubscribe vlc
When reporting bugs, try to be as precise as possible (which OS, which
distribution, what plugins you were trying, and so on).
