By Vreixo Formoso and Thomas Schmitt Integrated sub project of libburnia-project.org. http://files.libburnia-project.org/releases/libisoburn-0.3.6.pl00.tar.gz Copyright (C) 2006-2009 Vreixo Formoso, Thomas Schmitt. Provided under GPL version 2. ------------------------------------------------------------------------------ libisoburn is a frontend for libraries libburn and libisofs which enables creation and expansion of ISO-9660 filesystems on all CD/DVD/BD media supported by libburn. This includes media like DVD+RW, which do not support multi-session management on media level and even plain disk files or block devices. The price for that is thorough specialization on data files in ISO-9660 filesystem images. So libisoburn is not suitable for audio (CD-DA) or any other CD layout which does not entirely consist of ISO-9660 sessions. Currently it is fully supported on Linux with kernels >= 2.4 and on FreeBSD versions with ATAPI/CAM support enabled in the kernel, see atapicam(4). On other X/Open compliant systems libburn will only offer POSIX i/o with disk file objects, but no direct MMC operation on CD/DVD/BD drives. By using this software you agree to the disclaimer at the end of this text: "... without even the implied warranty ..." Compilation, First Glimpse, Installation Dynamic library and compile time header requirements for libisoburn-0.3.6 : - libburn.so.4 , version libburn-0.6.4 or higher - libisofs.so.6 , version libisofs-0.6.16 or higher libisoburn and xorriso will not start with libraries which are older than their headers seen at compile time. So compile in the oldest possible installation setup unless you have reason to enforce a newer level of bug fixes or features. Obtain libisoburn-0.3.6.pl00.tar.gz, take it to a directory of your choice and do: tar xzf libisoburn-0.3.6.pl00.tar.gz cd libisoburn-0.3.6 Within that directory execute: ./configure --prefix=/usr make Then become superuser and execute make install which will make available libisoburn.so.1 and program xorriso. For the API concepts and calls see ./libisoburn/libisoburn.h as well as /usr/lib/libisofs/libisofs.h /usr/lib/libburn/libburn.h xorriso libisoburn comes with a command line and dialog application named xorriso, which offers a substantial part of libisoburn features to shell scripts and users. Its file xorriso/README describes a standalone tarball as first preference for statically linked xorriso installation. The libisoburn installation described above produces a dynamically linked xorriso binary depending on libburn.so, libisofs.so, libisoburn.so. After installation documentation is available via man xorriso Several alias links point to the xorriso binary: xorrisofs starts xorriso with -as mkisofs emulation already enabled xorrecord starts xorriso with -as cdrecord emulation already enabled osirrox starts with -osirrox image-to-disk copying already enabled By default xorriso will depend on libreadline if the readline-dev headers are present. This dependcy can be avoided by running ./configure --prefix=/usr --disable-libreadline make clean ; make Never omit the "make clean" command after switching libreadline enabling. Drives and Disk File Objects The user of libisoburn applications needs rw-permission for the CD/DVD burner devices which shall be used. A list of rw-accessible drives can be obtained by xorriso -devices resp. by libburn API call burn_drive_scan() A possible source of problems are hald or other automounters. If you can spot a process "hald-addon-storage" with the address of your desired drive, then consider to kill it. If you cannot get rid of the automounter that easily, try whether it helps to always load the drive tray manually before starting a write run of xorriso. Wait until the drive light is off. Better try to unmount an eventually mounted media before a write run. Besides true optical drives, libisoburn can also address disk files as input or output drives. The addresses of the disk files have to be preceded by "stdio:". Like: "stdio:/tmp/pseudo_drive" Note: xorriso by default prefixes "stdio:" to addresses outside the /dev tree if they do not lead to an optical drive device file. Testing We are quite sure that libisofs produces accurate representations of the disk files. This opinion is founded on a lot of test burns and checks by a little test program which compares files from the mounted image with the orignals on disk. It uses the normal POSIX filesystem calls, i.e. no libburnia stuff. This program is not installed systemwide but stays in the installation directory of the xorriso tarball as test/compare_file . Usually it is run as -exec payload of a find command. It demands at least three arguments: The path of the file to compare, the prefix1 to be cut off from path and the prefix2 which gets prepended afterwards to obtain the path of the second file to compare. As further argument there can be -no_ctime which suppresses the comparison of ctime date stamps. The exit value is 0 if no difference was detected, non-0 else. Example: After xorriso ... -pathspecs on -add /=/original/dir -- mount /media/dvd cd test compare tree /media/dvd with tree /original/dir : find /original/dir -exec ./compare_file '{}' /original/dir /media/dvd ';' \ | less and vice versa: find /media/dvd -exec ./compare_file '{}' /media/dvd /original/dir ';' \ | less ------------------------------------------------------------------------------ This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License version 2 as published by the Free Software Foundation.
