Ok, into the next level:

Last one for today:

GL Enum Problem Test #4

Feels like I'm peeling an onion.. I just keep finding more and more levels of nested code - we haven't quite made it to GL yet..  I'm starting to see how much extra baggage SDL is adding to this project.  Removing it should really simplify things a lot.

an thanx again will check in tomorrow.

[Paul]

Ok, great, we've made it down to actual GL calls (finally!)  This one *should* pinpoint exactly which line is producing the invalid enum error (there are a couple places it could go in another layer or two, but hopefully not, haha!)

GL Enum Problem Test #5

Once I have the line, I can do some googling and ask around on various forums to see if anyone knows the cause and (hopefully) a solution.

Excellent, that logged the problem nicely:

Code: [Select]

V/SDL_render_gles2.c( 3302): ----(18a)
W/        ( 3302): error  of type 0x500 glGetIntegerv
V/SDL_render_gles2.c( 3302): ----(18b)
V/SDL_render_gles2.c( 3302): ----gl error
Which tracks the problem down to the following code:

Code: [Select]

glGetIntegerv( GL_NUM_SHADER_BINARY_FORMATS, &nFormats );
glGetBooleanv( GL_SHADER_COMPILER, &hasCompiler );
if( hasCompiler )
    ++nFormats;
rdata->shader_formats = (GLenum *) SDL_calloc( nFormats, sizeof( GLenum ) );
glGetIntegerv( GL_SHADER_BINARY_FORMATS, (GLint *) rdata->shader_formats );   <---- PROBLEM HERE
Specifically, it is reporting an invalid enum for that last line.  I've posted a question on Stack Overflow, so hopefully someone will be able to shed some light on this.

[Paul]

Ok, I think I solved that problem.  It looks like, against the specification, because your device does not support any binary shader formats, the library assumes no one would call GL_SHADER_BINARY_FORMATS when GL_NUM_SHADER_BINARY_FORMATS is 0.

There are probably still other problems later in the initialization process now that it will be able to get past that line, though.  If it is still crashing with this test, then please post the logcat output.

GL Enum Problem Test #6

Thanks again for helping me track this one down!

still crashes when opening a rom

[br1ttan]

i also herd a slight noise you know that coin sound when mario starts it makes that sound but jus a part of it befor it crashes

[Paul]

Interesting.. looks like my theory was wrong, and GL_NUM_SHADER_BINARY_FORMATS isn't zero.  Let's see how many are being returned then.  Please provide the logcat after running this test:

GL Enum Problem Test #7

[br1ttan]

i think you did it lol it worked for the first time on mario 64 but its extremely choppy and slow... should i still post a alogcat for you 

[Paul]

Yes, there is still a problem in there somewhere, so the logcat might be helpful.  Glad it is at least running now!
