Following up from post getting OT in thread:
I started with working code from the AppWizard. tabs/spaces is pushing the formatting everywhere:
You might be missing some of the modern WM6 calls. Here's the relevant code from the working ported version of Graphics for the Masses.

}I'm using evc4, so I can't build for a THUMB ( wince 5.0 ) device... any way you can recompile the lib for ARMv4?
Otherwise, I'm still linking w/ the Vincent lib.
Anyway, I started a whole new app ( appwizard hello template ) instead of writing the winmain from scratch and I still cannot generate a surface when I have anything but EGL_NONE in the config requests.
One thing I note is that fps is about 47-48, but once again, the texture is not mapped onto the object. If I put it in my folder w/ the Vincent dll, the texture is mapped and the fps is about 11-12.
I'm not quite familiar w/ EGL, but... does anyone know the EGLConfig structure? I tried searching for it to see what the requested width/height per config was so I can debug why the surface just doesn't get created.
anyway, here's my code:

That's ARMv4 or ARMv4i? I'm going to assume latter because that's what most of the dlls seem to be targeting. I'll put this up soon.
Meantime, GetClientRect() on your hwnd and make sure the rect is sane before you pass it on to eglCreateWindowSurface().
Also, Imageon may work better with GLfloat values although it probably kills Vincent (with software emulation on the ARM without native FP support in armv6 by the compiler) with anything but GLfixed. Try some benchmarking to see which works out better.

ARMv4 is what evc4 targets...
GetClientRect() is giving me very sane values, 268x240... 268 due to the bars up top & below.
I guess I'm just confused as to why Vincent is able to properly create the proper surface while our drivers cannot...
Edit:
I just realized that you don't provide egl config attribs for for eglCreateWindowSurface or for eglCreateContext... huh. Doing that, the surface and context are created ok, but the texture still isn't loaded... mebbe a problem w/ texture loading.

That's just rude, dood... lolIn the words of the great Sammy L.
Anywho, it looks like the problem w/ texturing is that our drivers do not seem to support mipmap. By commenting out the linear mipmap flag when loading the texture, we get a fully working opengl es test app.
I get about 44 fps.See for yourselves.

@nushrike, both of your libgles_cm.lib's are designed for the 'THUMB' device. It's ok. I'll just keep on linking to the vincent lib.
Just remember that our driver does not support mipmap.
I think it's eVC is too old then. It's been thumb since WinCE5. Most all the system libs I have to link to insiste on Thumb -- if I set it to ARM, it refuses to link. Hey, that's an idea.. I'll try ARM to see if it generates any .lib.
For hardware, or supported mipmapping (software or not), look up glGenerateMipmapOES(GL_TEXTURE_2D). The tech demo I posted earlier demonstrates this. It's that blurry looking rotating texture behind the checker-board and various other textures.
edit: nope, can't create a dummy .lib by trying to link ARM.
Instead, you can modify Vincent to fake-support the extended functions as you need them and as they exist in the HWA .dll exports list. Here's an example:

extern "C" {
#endif
{
GL_APICALL void GL_APIENTRY glGenerateMipmapOES (GLenum target)
{ return; }
#ifdef __cplusplus
}
#endif

No code to make it a SourceForge project. Now, if it was code to make the drivers, that would be worthy.
ycavan: figured out your bug. You have to pass NULL for configAttrib (the last parameter) for eglCreateContext, and eglCreateWindowSurface. Also, using glGenerateMipmapOES(GL_TEXTURE_2D) with your source, texture works fine now. Same FPS. I'm seeing if converting to GLfloat will speed it up.
edit: float is no speed increase so far, but no decrease either.

How do you get this to run? I've already asked you in PM that WinCE doesn't support the concept of "current working directory" and you use in your code.
I'm sorry about not responding to the pm's... lol, I just didn't see them.
Anyway, just unzip the file on your pc and copy the exe and resources folder to your device and run the exe. Just make sure to keep the exe and resources folder together.

It doesn't work for me after I drop it into the "Program Files" folder because this code is hard-coded for root directory then.
really odd... i ran the program in its own directory w/o a problem... i'm @ work, so i'll check it out when i get home.
it looks like the "resources" directory must be on the root of the device...
I'm working on finding the cwd, but loading resources fails even though it's the correct wd...
You guys can try and see if this works...
sPath should contain the working directory... but my app is failing the resource loads even though this is the same full path as before...

Code:
TCHAR tPath[255];
char sPath[255];
// get full path to this executable
GetModuleFileName(NULL,tPath,255);
// find the last '\'
TCHAR* pos = wcsrchr(tPath,'\\');
// end the string after the last '\'
*(pos+1) = '\0';
// copy wide char array to multi-byte string
wcstombs(sPath,tPath,255);

this can be very intresting for xda flame with goforce? can you build the libs because there is no SDK avialeble, the test app doesn't work message:
OpenGL ES init error:
eglInitialize
OpenGL ES init error:
eglInitialize
EDIT:
Just realized that you're talking about another phone w/ the goforce... lol
You will need to prolly google "goforce opengl es sdk" There should be quite a few out there.
On another note... I figured out the problem with working directory resource loading.
I prefer to make a call once when it's something configuration-related... like storing my current working directory... it seems that evc4 doesn't like it when I do that so I had to update mesh.cpp and texture.cpp to perform the GetModuleFileName calls in each load function.
Here's an updated TestApp2. You just need to keep testapp2.exe and the resources directory together.
View attachment testapp2.zip
Updates include:
+ fullscreen now
+ up/down rotation
+ left/right acceleration -100 to 100
+ spouting of particles
Have fun guys.
The resources directory contains these files that you can change if you want to try different things.
spot.raw - the particle system's balls texture
font.raw - the font texture
knot.gsd - the main object mesh
fire128.tga - the mesh object's texture
