[Ogre on Linux] problem of compilation

[informatirien]

Hello,

I am a newbie with Ogre 3d I have tried to compile a sample code that it hasn't worked because the instruction #include "windows.h"

I need to know if there's a method to replace this instruction?

I'll be very grateful if you have a code that works on Linux.

Thank's.

Then don't use that sample then?

I am not aware of any official Ogre samples which uses that kind of code..

Which sample and from where?

This is the link from where i get the sample code

Yes, and where exactly is that #include "windows.h" line?

[informatirien]

yes in TutorialApplication.cpp
there is

#if OGRE_PLATFORM == OGRE_PLATFORM_WIN32
#define WIN32_LEAN_AND_MEAN
#include "windows.h"
#endif

That file will only be included if you're compiling on Windows. If you are running under Linux it'll never be included by the preprocessor.

How about you show us the error that your compiler is throwing?

Otherwise you can just delete that include as you're definitely not running on Windows right?

yes in TutorialApplication.cpp
there is

#if OGRE_PLATFORM == OGRE_PLATFORM_WIN32
#define WIN32_LEAN_AND_MEAN
#include "windows.h"
#endif

Yeah, I forgot about that.
It's called 'conditional compilation', and it won't present a problem for you because OGRE_PLATFORM will not be OGRE_PLATFORM_WIN32, right?

Instead of assuming things, let's get some facts on the table.

Areay is right.

Woot, first time for everything right? That's now my forum signature

Thank's ;
I compile the code but I have an other problem
when I run I get this line
InternalErrorException): Could not load dynamic library /usr/lib64/OGRE/RenderSystem_GL. System Error: /usr/lib64/OGRE/RenderSystem_GL.so: cannot open shared object file: No such file or directory in DynLib::load at /home/abuild/rpmbuild/BUILD/ogre_src_v1-7-4/OgreMain/src/OgreDynLib.cpp (line 91)

Sounds like the OpenGL Render System DLL is not where it is supposed to. In most cases it needs to be next to your EXE, but you can change that in the plugins.cfg file.

BTW: That at least how it works on Win, but I am not a Linux guy .

[Miscreant]

Check your plugins.cfg file (should be in the same directory as the application you compiled). It should say something like this: (with whichever plugins you're not using commented out with the "#")

Code: Select all

# Defines plugins to load

# Define plugin folder
PluginFolder=/usr/lib64/OGRE/

# Define plugins
# Plugin=RenderSystem_Direct3D9
# Plugin=RenderSystem_Direct3D10
# Plugin=RenderSystem_Direct3D11
 Plugin=RenderSystem_GL
# Plugin=RenderSystem_GLES
# Plugin=Plugin_ParticleFX
# Plugin=Plugin_BSPSceneManager
# Plugin=Plugin_CgProgramManager
# Plugin=Plugin_PCZSceneManager
# Plugin=Plugin_OctreeZone
# Plugin=Plugin_OctreeSceneManager

See if you can find RenderSystem_GL.so and change PluginFolder to wherever RenderSystem_GL.so (and your other plugins) are stored
