The 5.0 release of Indri marks major changes in the packaging of the Lemur Project software. All of the deprecations that were previously announced have been performed, with the Lemur Toolkit distribution retired. Users of the deprecated APIs SHOULD NOT upgrade from the Lemur Toolkit 4.12 to Indri 5.0. All of the lemur::api API elements have been removed.
Applications compiled with the Indri API require the following libraries: z, iberty, pthread, and m on linux. Applications built in Visual Studio require the additional library wsock32.lib. The java jar files were built with Java 6 (jdk 1.6.0). The java UIs require Java 6. We have tested using GCC 4.1.2 (CentOS 5.3 linux), 4.3.3 (Ubuntu 10.04 linux), 4.2.1 (OS/X), and Visual Studio 2008 (Windows Vista, WIN32 and x86_64).
