Installing PLSM

I'm trying to make use of PLSM2, but these docs are un-followable. So I've done the following ...

- downloaded the latest SVN source of ogre (which I think is 1.7.0).
- downloaded the gnu tarball on sourceforge of PLSM2.

But before I expand paginglandscape.tar into ogre, I can already tell that the Makefile.am in paginglandscape (and others) will overwrite the ones in the ogre dir. Is this the correct thing to do?

So ./Plugins, ./Samples, ./Tools, etc... of ./paginglandscape of the plsm gnu tarball seems like it should go in ./ogre ... but then things get overwritten.

Any help much appreciated.

I just use it as-is, separate to the Ogre source tree.
It's actually meant to (IIRC) be in ogreaddons folder, not ogre folder.

As far as ogreaddons dir goes, I didn't see one of those in the entire ogre tree. But I did give it a go at building it separately.

Anyways, here's a make after a ./bootstrap and ./configure.

I pulled ogre from the svn trunk. Should I be using an earlier version w/ PLSM (I read somewhere's to use the latest).

This is from trying to build paginglandscape w/ ogre 1.6.1 installed.

I'd be happy just to find any 1.6+ version of ogre that builds w/ PLSM. I've tried 1.6, 1.6.1, and what's in SVN. All give different errors.

ogreaddons folder is separate to ogre folder. Two separate folders. For two separate projects.

It looks like you didn't inform your compiler where OgreOctreeSceneManager.h is.
Add the location of the OctreeSceneManager to your projects include paths, and tell it to link to OgreOctreeSceneManager library too. (If needed on Linux / GCC).
(I am pulling the names from the top of my head, because I haven't the Ogre source handy atm).

So my layout looks like this ...


- ogre (1.6.1)
|
- ogreaddons
|- paginglandscape


I've built ogre. Then I run the following in ./paginglandscape ...

./bootstrap
./configure --includedir=/home/winky/Tools/ogre/Plugins/OctreeSceneManager
make

And even though this file is located in the ./configure --includedir given above, I still get ...

Did you do this differently?

I did it like this:
./aclocal
./bootstrap
./configure
make
sudo make install
It was some time ago, but it should still work.

Heh, if it were that easy, it would have worked for me days ago.

Heh, if it were that easy, it would have worked for me days ago.
I didn't mean to call it easy.
There's something wrong here.
You're using Ogre 1.6 and PLSM2 from trunk?
That should definitely work.
Did you install Ogre in /usr/local or just /usr ?

No, not from trunk, it's the source tarball of 1.6 I downloaded (which I guess should be from trunk). I installed ogre by default, /usr/local.
Same results. I build ogre, then in a separate ogreaddons dir, I build paginglandscape ...

I downloaded the GNU tarball from this page ...
http://ogreaddons.svn.sourceforge.net/v ... landscape/

Untarred it in the ogreaddons dir ...

|- ogre
|- ogreaddons
|- paginglandscape


And ran the commands after ogre was installed.

You could try building with _PLSM_OCTREE defined:

CXXFLAGS='-D_PLSM_OCTREE' ./configure

or if you want to build against the OctreeSceneManager try playing about with the configure flags, e.g:

CPPFLAGS='-I/media/sda1/LIBRARIES/OGRE/ogre-v1-6-1/PlugIns/OctreeSceneManager/include' LDFLAGS='-Wl,-rpath,/usr/local/lib/OGRE -Wl,--start-group -Wl,/usr/local/lib/OGRE/Plugin_OctreeSceneManager.so -Wl,--end-group' ./configure


There are also appears to be a few ifdef/enum problems on linux:

It actually compiled all the way through using ...


$ CXXFLAGS='-D_PLSM_OCTREE' ./configure


So I try to run the Samples/PagingLandScape2/src PagingLandScape2 executable, and in the plsm2.log I see ...

...

12:47:11: *-*-* OGRE Shutdown


Now, there's a Plugin_PagingLandScape2.so that has been built, but nowhere's on my system in the src or install dir is there a Plugin_PagingLandScapeSceneManager2.so.

Is this a confusion of the two or should there really be a Plugin_PagingLandScapeSceneManager2.so? I don't see any errors during the build process.

The plugin on linux is named "Plugin_PagingLandScape2.so" for some reason. You could either:

a) update the map splitter source to reflect this, see last post here
viewtopic.php?f=2&t=8708
b) as a quick work around to run the map splitter create a soft link to Plugin_PagingLandScapeSceneManager2
>> cd /usr/local/lib/OGRE
>> sudo ln -s Plugin_PagingLandScape2.so Plugin_PagingLandScapeSceneManager2.so

Also you should run MapSplitter from paginglandscape/Samples/Common/bin where everything is set up.

Ok, almost there. Thanks for the other links. After getting past a few hf.cfg errors, other assertion failuers, etc ... I'm getting the following startup error ... seems to be looking for a file named hf129_3.0.0.png which I know doesn't exist.

Any ideas?

Not really sure what's going on with it. I somehow thought to run MapSplitter, and it ends w/ a Segmentation Fault.

Segmentation fault


However, after that, I was finally able to get the demo working, but don't quite understand how to use it. With the orange square around the cursor, if I click on the map, it crashes with more segmentation faults.

All I see is what looks like a birds eye view of a single square (tile?) of land. Not other tiles around it. In fact, it seems as if I do anything w/ swapping tiles, N, L, P ... it will crash, as if the MapSplitter didn't cut things up correctly.

I think the problem with the seg fault is that the plugin is being loaded from the cfg file and in code. To resolve the seg fault try commenting out Plugin_PagingLandScape2 in plugins.cfg and
uncomment to run the demo.

With regards to the demo, sorry I don't know. I have the same problems, it's never worked properly for me on Linux or Windows.

You could check the wiki for a sample PLMS2 application (though it probably needs updating).
Also the ogreode Landscape demo from svn(ogreode/demos/Landscape) has a sample using PLSM2, try stripping out the physics related code. Sorry can't post link's since my internet connection is in meltdown.

Man, this is taking some serious time to get up and running. So, while I keep trying to get this stuff going, not even knowing if it eventually will ...

Can I ask ... what other paged terrain packages are out there that will run on linux?

Did you try running and building the above demo?

Try searching on the main forum for threads such as the Simple Paged Terrain:
http://www.ogre3d.org/forums/viewtopic.php?f=11&t=31674

Did you try running and building the above demo?


Yeah, I've got added in what you posted. But I can't get the extra paged tiles to appear outside of the one in the center that I've got in my small app.

I couldn't find the example that you were talking about in the ode 0.11 src which I grabbed.

Update:
I just feel I'm so close. My problem is just that my terrain isn't there, I can't see it, after a bit of moving around, then it crashes and I don't know why yet.

And simple paged terrain is a project that is now dead, or at least till the entire rewrite comes out. Ugh.

The demo I referred to was the OgreOde Landscape demo which is pretty much the above code with the physics stuff taken out.
http://ogreaddons.svn.sourceforge.net/v ... Landscape/

Regarding your problem with paged tiles, I don't know. On Linux I had problems with loading terrains such as alpes. It appears that MapSplitter didn't create alpes0.0.png and the demo failed loading "alpesx.x.png", as a workaround I renamed the files to "alpes.x.x.png".

Ok, I think I may have found something that results in the following error.

Is the scenemanager not being found, and if so, what is it that I'm missing here?

I think I have the necessary libs here ...

I thought I'd post what I had to get PLSM2 to work on linux, for reference to others (I hope I didn't forget anything).
Make sure you use ogre svn v1-6, not trunk: https://svn.ogre3d.org/svnroot/ogre/branches/v1-6

chmod +x bootstrap.sh
edit bootstrap.sh and comment out the three lines about libtool check
edit Samples/Common/include/PagingLandScape2Application.h not to load Plugin_PagingLandScapeSceneManager2
./bootstrap
CXXFLAGS='-D_PLSM_OCTREE' ./configure
make
sudo make install
go into Samples/Common/bin/ and make sure resources.cfg is fine
run MapSplitter
use the code dermont posted to test PLSM

Hello everybody.
I need help to install PLSM2 with Ogre SDK 1.6 on Windows for Visual Studio 2005 (2008 is ok too).
I read all the topic but I can't understand the parts with Linux (should I leave windows ? )
I tried also the directives shown on the Ogre wiki to install the PLSM2 http://www.ogre3d.org/wiki/index.php/Paging_Scene_Manager_Installation, but it still not working.

It will be great if someone can tell us how do get it run, we need the pOwer of this plugin !
Moreover a tutorial will help a lot to everybody.

I am french, so I am apologize if there are some mistakes in the post.

@dermont: Thx, patch applied.

I think with DragonM's patch for MapSplitter the hack to add the initial String(".") to the filename isn't required:
