Ogg project codecs use the Ogg bitstream format to arrange the raw,
compressed bitstream into a more robust, useful form. For example,
the Ogg bitstream makes seeking, time stamping and error recovery
possible, as well as mixing several sepearate, concurrent media
streams into a single physical bitstream.
## What's here ##
This source distribution includes libogg and nothing else. Other modules
(eg, the modules libvorbis, vorbis-tools for the Vorbis music codec,
libtheora for the Theora video codec) contain the codec libraries for
use with Ogg bitstreams.
Directory:
- `src` The source for libogg, a BSD-license inplementation of the public domain Ogg bitstream format
- `include` Library API headers
- `doc` Ogg specification and libogg API documents
- `win32` Win32 projects and build automation
- `macosx` Mac OS X project and build files
## Contact ##
The Ogg homepage is located at https://www.xiph.org/ogg/ .
Up to date technical documents, contact information, source code and
pre-built utilities may be found there.
## Building ##
#### Building from tarball distributions ####
./configure
make
and optionally (as root):
make install
This will install the Ogg libraries (static and shared) into
/usr/local/lib, includes into /usr/local/include and API
documentation into /usr/local/share/doc.
#### Building from repository source ####
A standard svn build should consist of nothing more than:
./autogen.sh
./configure
make
and as root if desired :
make install
#### Building on Windows ####
Use the project file in the win32 directory. It should compile out of the box.
#### Cross-compiling from Linux to Windows ####
It is also possible to cross compile from Linux to windows using the MinGW
cross tools and even to run the test suite under Wine, the Linux/*nix
windows emulator.
On Debian and Ubuntu systems, these cross compiler tools can be installed
by doing:
sudo apt-get mingw32 mingw32-binutils mingw32-runtime wine
Once these tools are installed its possible to compile and test by
executing the following commands, or something similar depending on
your system:
./configure --host=i586-mingw32msvc --target=i586-mingw32msvc --build=i586-linux
make
make check
(Build instructions for Ogg codecs such as vorbis are similar and may
be found in those source modules' README files)
## Building with CMake ##
Ogg supports building using [CMake](http://www.cmake.org/). CMake is a meta build system that generates native projects for each platform.
To generate projects just run cmake replacing `YOUR-PROJECT-GENERATOR` with a proper generator from a list [here](http://www.cmake.org/cmake/help/v3.2/manual/cmake-generators.7.html):
cmake -G YOUR-PROJECT-GENERATOR .
Note that by default cmake generates projects that will build static libraries.
To generate projects that will build dynamic library use `BUILD_SHARED_LIBS` option like this:
cmake -G YOUR-PROJECT-GENERATOR -DBUILD_SHARED_LIBS=1 .
After projects are generated use them as usual
#### Building on Windows ####
Use proper generator for your Visual Studio version like:
cmake -G "Visual Studio 12 2013" .
#### Building on Mac OS X ####
Use Xcode generator. To build framework run:
cmake -G Xcode -DBUILD_FRAMEWORK=1 .
#### Building on Linux ####
Use Makefile generator which is default one.
cmake .
make
