hi..

Runing nmake SampleBrowserDummy command, throws me at 51% the following errors

I got the same thing - managed to get it to work by removing the *almost* duplicated code sections that were added to

OgreGLES2FrameBufferObject.cpp:

Code: Select all

#if OGRE_PLATFORM == OGRE_PLATFORM_ANDROID
    void GLES2FrameBufferObject::notifyOnContextLost()
    {
        mManager->releaseRenderBuffer(mDepth);
        mManager->releaseRenderBuffer(mStencil);
		mManager->releaseRenderBuffer(mMultisampleColourBuffer);
        
        glDeleteFramebuffers(1, &mFB);
        GL_CHECK_ERROR;
        
		if (mMultisampleFB)
			glDeleteFramebuffers(1, &mMultisampleFB);
        
        GL_CHECK_ERROR;
    }
    
    void GLES2FrameBufferObject::notifyOnContextReset(const GLES2SurfaceDesc &target)
    {
        /// Generate framebuffer object
        glGenFramebuffers(1, &mFB);
        GL_CHECK_ERROR;
        
        glBindFramebuffer(GL_FRAMEBUFFER, mFB);
        GL_CHECK_ERROR;
        
        // Bind target to surface 0 and initialise
        bindSurface(0, target);
        GL_CHECK_ERROR;
    }
#endif

and OgreGLES2HardwareOcclusionQuery.cpp:

Code: Select all

//------------------------------------------------------------------
#if OGRE_PLATFORM == OGRE_PLATFORM_ANDROID
void GLES2HardwareOcclusionQuery::notifyOnContextLost()
{
        destroyQuery();
}
//------------------------------------------------------------------
void GLES2HardwareOcclusionQuery::notifyOnContextReset()
{
        createQuery();
}
#endif

Both files are located in %OGRE_HOME%\RenderSystems\GLES2\src

I removed that duplicate code thanks for pointing these happen during back merge from 1.9 branch - i also have merged back 1.9 to default the should be in sync but if you guys encounter something just let me know so i can fix it asap.

That means i can download the fix from the repository?

If yes may you give me the repo url? thanks.

I just built ogre and the SampleBrowserNDK as directed in the quick start guide. However, I found there was a step missing in the building the SampleBrowserNDK section. After running:

Code: Select all

ndk-build

I had to run:

Code: Select all

android update project -p . -a

... in order to create the "build.xml" file. Afterwords, I was able to successfully build & install it with the ant tool.


*****
And just a little note to the gui-oriented people: I had no trouble using cmake-gui to generate the project files ... just be sure to add the OGRE_DEPENDENCIES_DIR and ANDROID_API_LEVEL keys before hitting configure. Also, when you hit configure, it will bring up the generator selection dialog. Be sure to select the right nmake in the dropbox and select the "specify toolchain" radio button (which will set the CMAKE_TOOLCHAIN_FILE key for you). Then you can hit "configure", adjust whatever keys want, hit "configure" again, and finally generate.

That's interesting. the nmake file should have those in it. Might be something that happened during one of the latest commits?

I've been founded an interesting tool to build android projects under visual studio http://visualgdb.com/tutorials/android/. I was tryed, and really works great, you can connect your device run ogre and put some break points and see what's happening. But i only can test the OgreJNI project, when i load the sample browser and try to compile, a bunch off errors appear

[Wolfmanfx]

OgreJNI do not use NativeActivity maybe thats the reason

[Siedge]

Okay so really new to ogre (Really grateful for what you guys are doing here quite awesome!)
and well when trying to build for android this is what i get.

Are you sure you're using Ogre 1.9 ? apparently it couldn't find the toolchain.

[Siedge]

yes its 1.9 and the toolchain isn't there but it is in C:\sinbad-ogre-61e819c74682\CMake\toolchain but if i tell it to use that i get

[Siedge]

Still no help i have been trying but i have no idea what i did wrong

[DanielSefton]

Hi guys,

Building Ogre for Android is indeed quite confusing. I wrote a step-by-step guide (edit: for mac) which covers the quirks: http://www.danielsefton.com/2013/04/bui ... n-mac-osx/

[Wolfmanfx]

You should use the vs dev console i think the cmake gui makes the quirks

[DanielSefton]

You mean terminal? (mac)

Well I prefer working with the GUI, and my guide works with the GUI

[Wolfmanfx]

the gui can not use the toolchain correctly try the console on mac

Hello there, I've succesfully runned my Ogre project in my Galaxy Note 10.1 thanks to this great 1.9 RC1 release, it works like a charm!

But I've noticed something that it looks like a bug, when I enable the wireframe view on any project, it looks like it is showing more wire thant it should, I don't know how to explain this better, so I've take some screenshoots to show it better:

The Bezier Patch from the SampleBrowser:
With wireframe:
http://imagebin.org/256532
Without wireframe:
http://imagebin.org/256531

My project:
With wireframe:
http://imagebin.org/256533
Without wireframe:
http://imagebin.org/256534
With wireframe from my desktop build just for comparison:
http://imagebin.org/256530

Thanks!

[c6burns]

You can see what he's showing by switching to wireframe on almost any geometry. It's noticeable on the Bezier at lower mesh detail. I have an ocean made with projected grid and there are 2 of them in my app when I am in wireframe mode. Doesn't bother me, but thought I would clarify that it isn't some isolated issue.

Hi! I'm trying to make Ogre for GLES1 but cmake ignore some of my flags:

Code: Select all

cmake .. -DANDROID_NATIVE_API_LEVEL=9 -DOGRE_BUILD_RENDERSYSTEM_GLES=TRUE -DOGRE_BUILD_RENDERSYSTEM_GLES2=FALSE -DOGRE_BUILD_COMPONENT_RTSHADERSYSTEM=FALSE -DCMAKE_TOOLCHAIN_FILE="/../CMake/toolchain/android.toolchain.cmake" -DOGRE_DEPENDENCIES_DIR="../AndroidDependencies"

and result is:

Code: Select all

----------------------------------------------------------------------------
  FEATURE SUMMARY
----------------------------------------------------------------------------

Building components:
  + Overlay
Building plugins:
  + Octree scene manager
  + Particle FX
Building rendersystems:
  + OpenGL ES 2.x
Building executables:
  + Samples
Building core features:
  + DDS image codec
  + PVRTC image codec
  + ETC1 image codec
  + FreeImage codec
  + ZIP archives

GLES2 isn't supported by some devices and GLES1 is enough for me.
But is precompiled OgreSDK_Android_v1-9-0RC1 from http://sourceforge.net/projects/ogre/fi ... e/1.9/RC1/ GLES1 sample flooding in console by this message:
"E/libEGL ( 1976): called unimplemented OpenGL ES API"
I want to try to fix it. That's why I'm trying to compile Ogre GLES1 by myself...

Here is a list of devices that give this warning:
Asus Nexus 7
Asus Eee Pad Transformer TF300T
WEXLER TAB 7000

No warnings on devices:
Amazon Kindle Fire HD 8.9
Samsung Nexus 10
LG Optimus G E975

-DANDROID_GLES_ONLY=true works... c6burns, thanks!

[c6burns]

Hi! I'm trying to make Ogre for GLES1 but cmake ignore some of my flags

Try -DANDROID_GLES_ONLY=true

On another note, my build (following the wiki of course) comes out in 16 bit color, which is instantly noticeable on the loadup and sample main screen. Where did I go wrong and/or how do I fix that?

[Wolfmanfx]

Yeah you can change that via custom renderwindow attribute

[c6burns]

Sure, at first glance "maxColourBufferSize" would look like the option I need to set, except it already is set to 32. I was snooping around in the GLES2 Render System and in AndroidEGLWindow::_createInternalResources it calls EGLSupport::selectGLConfig with min and max values. selectGLConfig is taking the min values in my case for whatever reason (I didn't debug). If I restrict the min to 32 then pow I get my 32 bit color.

[hebdemnobad]

The wiki guide, http://www.ogre3d.org/tikiwiki/tiki-ind ... on=Android, does not state that Visual Studio is necessary to build ogre for android. Is it in fact a necessary app to follow the guide? Or can you open a visual studio command prompt without having visual studio installed? (I did a google search on this but couldn't find any guidance.)

The guide states that you need ant, but it doesn't say how, if at all, ant is used in any of the command line commands.

In any case, downloading visual studio express 2012 for win7 atm...
