Building OGRE as static library - Visual studio 2013

[codetemplar]

Hi all,

I am building ogre from source by using cmake. I added the dependencies I wanted, checked the "build Ogre as static library" checkbox, configured and then generated. No complaints. I then opened the sln file and built all projects as static libraries. All fine.

My game now successfully builds and links against the libraries but it throws an exception when run. Which is:

"exception(1813) The specified resource type cannot be found in the image file, in ConfigDialog::display"

It hasnt generated an ogre.cfg file and my plugins_d is pretty much empty as I shouldn't need my rendering system built as a plugin dll because I have statically linked against RenderSystem_Direct3D9Static_d.lib. This is my plugins_d file:

# Defines plugins to load

# Define plugin folder
PluginFolder=.

# Define plugins

See pretty much empty. I have no dll in my target folder as everything should be built into the exe. Have I missed something out?

This is my ogre.log file:

As you can see it is complaining about something it isn't creating.


Thanks

The problem was that as it is a static library the resource files were not getting loaded. So now I have the config dialog screen showing me which rendering system to choose from. However my options are empty. This is usually populated by the render systems plugins dll files, however as I said im static linking theses in as lib files. How can I get this populated?

Its probably because the linker is skipping the render system library from the build as it appears like it wont be used.

Im getting this link error:

libRenderSystem_Direct3D9-vc120-mt-sgd-1_9_0.lib(OgreD3D9EngineDll.obj) : warning LNK4221: This object file does not define any previously undefined public symbols, so it will not be used by any link operation that consumes this library

Would forcing this to statically link solve this issue?

Thanks

I don't know how up to date it is (I don't do static builds, so don't know the exact steps), but there's a page about it here: http://www.ogre3d.org/tikiwiki/tiki-ind ... ticLinking
Basically the problem is that render systems (and all other plugins like scene managers, particle effects, cg, etc) are typically initialised and added to the Ogre root automatically as they are loaded by plugins.cfg. But in a static link, no dynamic plugin loading is done (obviously). This means even if you link with the plugins and include their headers, they are never initialised. You need to do that manually.
For example, the particle system plugin requires something like this to be recognised: (put it after root is initialised, but before the config dialog)

Code: Select all

#include "OgreParticleFXPlugin.h"
 ..
 ..
 // Assumes mParticlePlugin is a member variable in your class somewhere
 mParticlePlugin = new ParticleFXPlugin();
 Root::getSingleton().installPlugin(mParticlePlugin);

The same is needed for the render systems, you need to create an instance of them then pass that pointer to ogre's root to install the plugin.

Perfect thank you. Who is responsible for deleting the plugin? Game or Ogre?


Thanks

Since you call new, you are responsible for calling delete.

Updating this old static build issue which I encountered exactly the same errors as the OP posted above.

The reason for this is OgreWin32Resources.rc.obj is being compiled but not linked to SampleBrowser:

viewtopic.php?p=554834#p554834

and not exclusive on VStudio but same on MinGW build.
