You will also need the +newest versions of autoconf, automake, libtool and pkg-config in +order to compile Vorbis from development source. A configure script +is provided for you in the source tarball distributions. + + [update or checkout latest source] + ./autogen.sh + make + +and as root if desired: + + make install + +This will install the Vorbis libraries (static and shared) into +/usr/local/lib, includes into /usr/local/include and API manpages +(once we write some) into /usr/local/man. + +Documentation building requires xsltproc and pdfxmltex. + +BUILDING FROM TARBALL DISTRIBUTIONS: + + ./configure + make + +and optionally (as root): + make install + +BUILDING RPMS: + +after normal configuring: + + make dist + rpm -ta libvorbis-<version>.tar.gz + +BUILDING ON MACOS 9: + +Vorbis on MacOS 9 is built using Metroworks CodeWarrior. To build it, +first verify that the Ogg libraries are already built following the +instructions in the Ogg module README. Open vorbis/mac/libvorbis.mcp, +switch to the "Targets" pane, select everything, and make the project. +Do the same thing to build libvorbisenc.mcp, and libvorbisfile.mcp (in +that order). In vorbis/mac/Output you will now have both debug and final +versions of Vorbis shared libraries to link your projects against. + +To build a project using Ogg Vorbis, add access paths to your +CodeWarrior project for the ogg/include, ogg/mac/Output, +vorbis/include, and vorbis/mac/Output folders. Be sure that +"interpret DOS and Unix paths" is turned on in your project; it can +be found in the "access paths" pane in your project settings. Now +simply add the shared libraries you need to your project (OggLib and +VorbisLib at least) and #include "ogg/ogg.h" and "vorbis/codec.h" +wherever you need to access Ogg and Vorbis functionality. + |
