[1.10.8] Can't compile RenderSystem_GLES2 for Android

nuke · Post by **nuke** » Sat Sep 16, 2017 3:15 pm

Hello!

I'm trying to compile v1.10.8 for Android and I am currently faced with multiple errors when compiling RenderSystem_GLES2 project

PRECONDITIONS:

Windows 10 x64
Visual Studio 2017 Pro
Android NDK r15c
targets: Android ARM,x86

These errors are due to modules hlsl2glsl and glsl_optimizer.
(Projects hlsl2glsl and glsl_optimizer are perfectly compiled as separate Android libraries!)

my OgreBuildSettings.h (scroll down please):

When I disable glsl_optimizer in my OgreBuildSettings.h as shown below:

Code: Select all

  #define OGRE_NO_VIEWPORT_ORIENTATIONMODE 1
  #define OGRE_NO_GLES2_CG_SUPPORT 0   
[color=#008000]//#define OGRE_NO_GLES2_GLSL_OPTIMISER 0  [/color]      
  #define OGRE_NO_GLES2_GLSL_OPTIMISER 1            [color=#008000]// NOTE: glsl_optimizer is DISABLED !!!! [/color]
  #define OGRE_NO_GL_STATE_CACHE_SUPPORT 1

..then errors 2,3,4,5 disappear, and there is an only error number 1.

But I need hlsl2glsl and glsl_optimizer to be included in project and work, because without glsl_optimizer there will be problems on some devices with a MALI chip (and they are actually the majority)
About glsl_optimizer and MALI (from http://www.ogre3d.org/developers/requirements):

...
ANDROID
We support all devices where the OS version is greater or equal 2.3.3 (this OS version introduced GLES 2.0 support). For older phones / tablets
we still have the GLES 1.1 rendersystem (which is not developed any further).
Furthermore we have partial support for GLES 3.X which should be used on newer devices.
In the past we had several problems with MALI gpu’s due the usage of the RTSS – some devices could not handle the auto generated shaders.
But we overcome most problems with the use of the glsl optimizer so that one should be enabled when running on mobile gpu’s.
...

........
Btw, I downloaded the Ogre v1.10.8 from this link:
https://github.com/OGRECave/ogre/releases/tag/v1.10.8

Help

I assume that the functionality of the use of glsl_optimizer is broken or not fully implemented in the Render System GLES2

try using ogre without hlsl2glsl (Cg) and glsl_optimizer and report any shader issues you run into. actually both mali drivers and ogre improved, so there should not be any issues any more.

Thank you very much for the answer!

As far as I understand, you are the main developer of version 1.10. (Maybe I'm wrong)
Simply, I at the same time I wanted to thank for the development of this engine and this branch (version).

Thank you

People like me (users of the engine) can not change or add functionality so competently that it does not lead to breakage or instability on some platforms.
Therefore, we only have to rely on developers.
The maximum I can do is identify errors when compiling or at runtime.

By the way, I changed the configuration...:

Code: Select all

[color=#00aa00]// #define OGRE_BUILD_PLUGIN_CG                 // OFF[/color]
[color=#aa00aa]#define[/color] OGRE_NO_GLES2_CG_SUPPORT      1         [color=#00aa00]// OFF[/color]
[color=#aa00aa]#define[/color] OGRE_NO_GLES2_GLSL_OPTIMISER  1         [color=#00aa00]// OFF[/color]

...and library libRenderSystem_GLES2.a successfully compiled.
I did not check how it works, because I did not build the whole solution (some components, all the samples and a sample browser need to be built)

I will continue to compile the project and write here if there are errors during compilation or testing.

By the way, is it planned to use hlsl2glsl and glsl_optimiser in the Render System GLES2?
Or is it no longer necessary?
