Hi to all
I have setup my toolchain with Codesurcery 2009q3 on Windows and wanna test something if it's builded correctly but don't have my Pandora... :pandora2ut4:

I was looking at this thread by darkblu
So inspired by this, i have made, a new Codeblock project with this darkblu's code and compiled two version of this example:

1) basic compilation option " -Wall -O2 " ---> file Test_GLES_Pandora.bin

2) Neon optimized option "-Wall -O3 -mcpu=cortex-a8 -ftree-vectorize -mfloat-abi=softfp -mfpu=neon" ----> file Test_GLES_Pandora_new.bin

I have included the source and project files ...so let me know if they work or i have made somthing wrong.

Thanks

Updated with the new code by darkblu

11/09/2010
Updated with proper Paeryn code suggestion ..Please test it

I think have understand what is not working ..(or loading in this case )..

bad shader source length for 'phong_bump_tang.glslv'.
bad shader source length for 'phong_bump_tang.glslf'.


The app will try to load these 2 files *.glslv and *.glslf but this are zero lenght.
If you substitute the files (and rename *.glslv & *.glslf) with the other *.glslv.back & *.glslf.back (or the *.new version ) it should work .

Thank you for your patience B)

Anyway now i know that my toolchain is working...this is good ;)

Disclaimer: I've just woken up, I may not be thinking properly yet.

I tried renaming (the *.bak files, then the *.new files), now when it's run the window pops up and closes straight away. I tried capturing some output but the terminal quits too. I sent the output to a file, it creates the file but there's nothing in it!

Thank you very much Gruso for your time..

Maybe i could build an SDL project to test my toolchain...or an already working app...before trying something like this.

hey Farox,

for some reason the reading of the shader source files fails. Here's the respective line in the code:
https://code.google....wse/app.cpp#693

(i do advise you to use this codebase, btw: https://code.google.com/p/test-es/ )


Make sure you have proper read permissions on these files. Also, Gruso can run an strace session from a ssh terminal (real-time feedback FTW) or to a log, and see what happens with file I/O:

DISPLAY=:0.0 strace ./test_es -frames 1

Running it in gdb on Pandora, I see it SEGFAULT'ing at:

0x40391f90 in __printf_fp() from /lib/libc.so.6


I tried to build the app with the included sources, but I get eglCreatWindowSurface() failed, EGL_BAD_NATIVE_WINDOW .. not sure if that has to do with the way I build it, though ..

Thank for testing torpor.
I dont know is is important but looking at the original thread i found this from paeryn :

I also changed the width and height to 256x256 as the pandora can't do a height of 512.


So if you could change this 
int main(int argc, char** argv)
{
        unsigned frames = -1U;
        unsigned skip_frames = 0;
        [b]unsigned w = 512, h = 512;[/b]

        bool cli_err = false;
to this ......................
int main(int argc, char** argv)
{
        unsigned frames = -1U;
        unsigned skip_frames = 0;
        unsigned w = 256, h = 256; //change to 256*256 

        bool cli_err = false;

<snip>

alternatively, you could just run it with the -screen parameter, which humbly resizes the app window on pandora ; )

topror, is that what you get when building under bullocks? can you add debug options to the build and check the backtrace in gdb?
edit: ah, bad window surfice is what you get, i originally misread you. do you have a eglGetDisplay(x11Display /*EGL_DEFAULT_DISPLAY*/) in the version you're compiling?

btw, as i'm still as pandora-less as i was when i originally posted the app, i cannot be of much help here with actual pandora lore.

darkblu: I do have that code, yes .. it appears there is something wrong with the setup of the window. I can't debug it now (working@real job) but I'll have another go at it tonight, since this is a topic that seriously interests me .. ;)

New package version 3 .
I found that Paeryn code suggestions (see it at http://www.gp32x.com...post__p__874167
and open the first Spoiler ) was lost on the new version of Darkblu code.

I have readded it ...so Please test and report . Thanks
