Dear HexiDave,
First of all, thank you very much for trying to help! Please don’t give up, and keep with me!
I checked plugins.cfg and the other .cfg files. They are ok, i think. Let me show you their contents:
plugins.cfg
# Defines plugins to load
# Define plugin folder
PluginFolder=.

quake3settings.cfg (i don’t really understand what this file is for… i don’t find chiropteraDM.pk3 anywhere… so i left this file like the others with their default contents)
<<<<<<< quake3settings.cfg

By the way, these files are in the C:OgreSDKbindebug folder. And in this folder there are the samples applications that i built from the project that comes in the C:OgreSDKMogre-Samples folder.
In the C:OgreSDKbindebug folder I also have these dlls:
CEGUIBase_d.dll
CeguiBindings.dll
CeguiDotNet.dll
CEGUIExpatParser_d.dll
CEGUIFalagardWRBase_d.dll
cg.dll
Mogre.Cegui.dll
Mogre.Demo.ExampleApplication.dll
Mogre.dll
MogreFramework.dll
MogreNewt.dll
MOIS.dll
OgreBindings_Cegui.dll
OgreGUIRenderer_d.dll
OgreMain_d.dll
OIS_d.dll
Plugin_BSPSceneManager_d.dll
Plugin_CgProgramManager_d.dll
Plugin_OctreeSceneManager_d.dll
Plugin_ParticleFX_d.dll
RenderSystem_Direct3D9_d.dll
RenderSystem_GL_d.dll
Yes, I think that all Ogre DLLs have _d. I think CeguiBindings.dll, CeguiDotNet.dll, cg.dll Mogre.Cegui.dll, Mogre.Demo.ExampleApplication.dll, Mogre.dll, MogreFramework.dll, MogreNewt.dll, MOIS.dll and OgreBindings_Cegui.dll don’t need ‘_d’, is it correct?
PS- please, don’t go away 
This is the first exception in my RoR.log. All I am trying to do is regen my cache and keep getting the Bad UTF-8 Continuation type.
If you need more info please dont hesitate to ask. I’ll keep trying to figure something out

I’m using Ogre 3D 1.9, and I’m trying to load a mesh contained in a folder pointed by the resource.cfg file. The folder contains sub-folders, that separate the .mesh files, .material files and textures. Here’s the content of the resource.cfg file:
# Resources required by the sample browser and most samples.
[Essential]
# Resource locations to be added to the default path
[General]
FileSystem=media
FileSystem=media/materials/scripts
FileSystem=media/materials/textures
FileSystem=media/models
After this i declare and initialize the mesh, materials and textures with the following:
Ogre::ResourceGroupManager::getSingleton().declareResource("ram.mesh", "Mesh", Ogre::ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME, Ogre::NameValuePairList());
Ogre::ResourceGroupManager::getSingleton().declareResource("char_ram_col.png", "Font", Ogre::ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME, Ogre::NameValuePairList());
Ogre::ResourceGroupManager::getSingleton().declareResource("char_ram_nor.png", "Font", Ogre::ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME, Ogre::NameValuePairList());
Ogre::ResourceGroupManager::getSingleton().declareResource("ram_skin.material", "Material", Ogre::ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME, Ogre::NameValuePairList());
Ogre::ResourceGroupManager::getSingleton().declareResource("ram_skin_eyelids.material", "Material", Ogre::ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME, Ogre::NameValuePairList());
Ogre::ResourceGroupManager::getSingleton().declareResource("ram_skin_eyes.material", "Material", Ogre::ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME, Ogre::NameValuePairList());
Ogre::ResourceGroupManager::getSingleton().declareResource("ram_skin_horns.material", "Material", Ogre::ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME, Ogre::NameValuePairList());
Ogre::ResourceGroupManager::getSingleton().initialiseAllResourceGroups();
Then i attach the mesh to a node:
Ogre::Entity *entity = scene->createEntity("LocalMesh_Ent", "ram.mesh");
Ogre::SceneNode *cube = node->createChildSceneNode("ram.mesh", Ogre::Vector3(x, y, z));
cube->attachObject(entity);
where cube is a SceneNode previously created.
I have problem loading the texture. The code is build without any problem, but when i run it i have the following error (in the log file):
OGRE EXCEPTION(7:InternalErrorException): Error decoding image in FreeImageCodec::decode at ........OgreMainsrcOgreFreeImageCodec.cpp (line 419)
The mesh and the materials are created correctly, if for example i comment the part regarding the texture.
Does anybody know which could be the problem ?
Second question: i read that the .png file has to be declared as Font, but there’s also the Texture option (which doesn’t work as well). Is that correct ?
Problem
I had an binary compiled on Ubuntu 14.04. I tried to run it on Ubuntu 16.04 and got this error:
OGRE EXCEPTION(7:InternalErrorException): Could not load dynamic library /usr/lib/x86_64-linux-gnu/OGRE-1.8.0/RenderSystem_GL
Solution
From the error, I could see that it was looking for an OGRE library file. I installed the OGRE library available on Ubuntu 16.04:
$ sudo apt install libogre-1.9-dev
The error still persisted, because Ubuntu 16.04 only has OGRE 1.9, while this binary was looking for OGRE 1.8 library files.
I tried to create a symbolic link of an OGRE 1.8 directory to the existing OGRE 1.9 directory:
$ cd /usr/lib/x86_64-linux-gnu/ $ ln -s OGRE-1.9.0 OGRE-1.8.0
This worked! The executable ran without problems. This saved me from having to build OGRE 1.8 from source on this computer.
When running rviz I get the following error messages:
[ WARN] [1414015276.298139367]: OGRE EXCEPTION(7:InternalErrorException): Could not load dynamic library /usr/lib/x86_64-linux-gnu/OGRE-1.8.0/RenderSystem_GL.

I’m running on Ubuntu 14.04 and ROS Indigo.
My graphics card info:
VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0102] (rev 09) (prog-if 00 [VGA controller])
UPDATE 1
Running rviz tries to compile against OGRE 1.8.1, and then gives the error messages above
[ INFO] [1414078694.030851551]: compiled against OGRE version 1.8.1 (Byatis)
and on this path
/usr/lib/x86_64-linux-gnu/
I have three versions of OGRE
OGRE-1.8.0/ OGRE-1.8.1/ OGRE-1.9.0/
UPDATE 2
So I removed all versions of OGRE.
First installed libogre-1.9-dev. For some reason, rviz was also removed from my machine. I tried to install it again, and it says:
The following packages have unmet dependencies:
ros-indigo-rviz : Depends: libogre-1.8-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
So I Installed libogre-1.8-dev and then installed rviz , but again getting the error messages above while running rviz and it crashes
UPDATE 3
Ok I uninstalled OGRE (and rviz automatically)
sudo apt-get remove libogre-1.8.0 libogre-1.8.0-dbg libogre-1.8-dev
I tried to install rviz and this time didn’t give any dependency error and automatically installed ogre too
sudo apt-get install ros-indigo-rviz
Just in case I also ran this command:
sudo apt-get install libogre-1.8.0 libogre-1.8.0-dbg libogre-1.8-dev
Currently in /usr/lib/x86_64-linux-gnu/ I have only these ogre folders:
OGRE-1.8.0/ OGRE-1.8.1/
