megasource/libs/libtheora-1.1.1/win32/VS2008

libtheora has libogg as a dependency, and for examples, also 

libvorbis, therefore you need to have libogg and libvorbis

compiled beforehand.



Lets say you have libogg, libvorbis and libtheora in the same directory:



libogg-1.1.4 

libvorbis-1.2.2

libtheora-1.0



Because there is no automatic library detection you have to,

either:



1. Rename libogg-1.1.4 to libogg, and libvorbis-1.2.2 to libvorbis.



2. Open libogg.vsprops with a text editor (even notepad.exe

will suffice) and see if LIBOGG_VERSION is set to the correct

version, in this case "1.1.4".



The same procedure should be done for libvorbis.vsprops and 

check LIBVORBIS_VERSION for the correct version, in this 

case "1.2.2".
