1libvorbis has libogg as a dependency, you need to have libogg 2compiled beforehand. 3 4Lets say you have libogg and libvorbis in the same directory: 5 6libogg-1.1.3 7libvorbis-1.2.0 8 9Because there is no automatic library detection you have to, 10either: 11 121. Rename libogg-1.1.3 to libogg 13 142. Open libogg.vsprops with a text editor (even notepad.exe 15will suffice) and see if LIBOGG_VERSION is set to the correct 16version, in this case "1.1.3" 17
