Building PLSM 2 demo from CVS

Hey, I can build the PLSM2 plugin and mapsplitter from CVS, however I am having some errors when building the demo. It first complained about not being about to locate OIS/OIS.h so I included the ogre dependencies folder as an extra include direction, the respective lib folders, however now I just get a series of linker errors in MSVC++ as follows:

Any help would be appreciate with getting this to compile. Also the mapsplitter gave me a runtime error when I ran it (I had to add "_d" to the end of the plugin name for PLSM2. But then it still gives a runtime error in the middle of mapsplitting on terrain.HSN.png. Thanks for the help!

These errors appear to be due to a project file with the incorrect settings. I recall making changes, but then I am running a non-standard build tree.

The quoted linker errors are not from building the plugin or the mapsplitter, but rather the demo application. We need to be clear here.

PLSM does not use OIS. The demos do. OIS is not required for PLSM applications, but was used for these demos. I stress this because I have seen a lot of OIS questions in the main forums, and there is almost universal confusion about whether OIS is part of OGRE, or required by it.

That said, lets look at building the demo application. For a release build, under the linker tab, select 'Input' and add to 'Additional Dependancies':

OgreMain.lib ois.lib


For a debug build place _d before before the .lib (ie ois_d.lib). Make sure you have changed this field in both build configurations.

The issue with the plugin name is probably due to the wrong import library being linked. Add Plugin_PagingLandScapeSceneManager2_d.lib to the additional dependancies for debug builds.

I'm not sure if CVS currently dumps everything into one binary folder. I split mine into Debug and Release, so it is clear what is being built and used.

If two folders are being used, make sure the correct working directory is used in the 'Debugging' tab.

Wow. I keep forgetting things like that. I had added the directories for the dependency libs, but forget to include the libs. Thats absurd. Thank you very much for pointing that out.
