GStreamer use a *large* array of tools and libraries, most of which are optional. We have attempted to make sure that any code that depends on optional libraries doesn't get built unless you have those libraries. If you find this not to be the case, please, let us know by filing a bug report at http://sourceforge.net/bugs/?group_id=1936. Required libraries: =================== glib v1.2.0 or better gtk+ v1.2.0 or better libxml Optional libraries: =================== gdk_pixbuf libgnomeui (for gstplay, gsteditor, autoplug example, several tests) libglade (for gstplay, gsteditor) libghttp (for httpsrc) libXv (for videosink) libxaudio (for xa mp3 decoder) libvorbis (for vorbisenc, vorbisdec) libcdparanoia (for cdparanoia ripper) liblame (for lame mp3 encoder) libshout (for the shoutcast plugin) for AVI playback you might want to get the windows libraries from http://divx.euro.ru/ and put the .dll files in /usr/lib/win32/ An extra set of tools is required if you wish to build GStreamer out of CVS (using autogen.sh): Required tools: =============== autoconf automake v1.4 or better libtool v1.3.5 or better Optional tools: =============== gtkdoc db2html fig2dev Optional debian packages: ========================= (This is an incomplete list, made only of problems which have been reported, rather than by an audit.) task-helix-gnome-dev OR libgnome-dev
