Build and Installation
Our build system is based on autotools. For preparing the build of a SVN
snapshot you will need autotools of at least version 1.7.
Check out from SVN by
svn co http://svn.libburnia-project.org/libburn/trunk libburn
go into directory libburn and apply autotools by
./bootstrap
From tarball
Alternatively you may unpack a release tarball for which you do not need
autotools installed.
Obtain libburn-0.5.8.pl00.tar.gz, take it to a directory of your choice and do:
To build a libburnia-project.org subproject it should be sufficient to go
into its toplevel directory (here: "libburn") and execute
tar xzf libburn-0.5.8.pl00.tar.gz
cd libburn-0.5.8
./configure --prefix=/usr
make
To make libburn accessible for running resp. application development,
and to install the cdrecord compatibility binary cdrskin, do:
make install
and to install the cdrecord compatibility binary cdrskin, do
(as Superuser):
make install
Above procedure installs cdrskin depending on libburn.so.4 .
This procedure installs libburn.so.4 and cdrskin depending on it.

From the view of cdrskin they behave much like DVD-R. Each track gets wrapped
into an own session, though.
DVD+R DL appear as extra large DVD+R. cdrskin does not allow to set the address
of the layer break where a reading drive might show some delay while switching
between both media layers.
BD-R are sold unformatted blank. If used without initial formatting then the
drive is supposed to format them to maximum payload size with no Defect
Management (see also above with BD-RE).
If Defect Management is desired then BD-R need to be formatted before the
first attempt to write a session to them.
blank=format_if_needed will detect the situation and eventually apply
default sized Defect Management formatting.
