Won't build on ArchLinux

[GoogleCodeExporter]

What steps will reproduce the problem?
1. check out svn
2. cmake .
3. make -j2

The building fails with this output:

/tmp/friking-shark-read-only/GameGraphics/OpenGLTexture.cpp: In function 
‘bool LoadPngFile(const char*, unsigned int, unsigned int*, unsigned int*, 
unsigned char**)’:

I think ArchLinux might have some new version of a png lib that the game uses.

Hi, can you try this:

In OpenGLTexture.cpp, 

Can you replace png_voidp_NULL with NULL ?

and add "#define PNG_NO_PEDANTIC_WARNINGS" like this...

#include "./stdafx.h"
#include <stdint.h>
#include "OpenGLGraphics.h"
#include "OpenGLTexture.h"
#define PNG_SKIP_SETJMP_CHECK
#define PNG_NO_PEDANTIC_WARNINGS
#include <png.h>

If this works, i can commit the change inmediatelly.

Thanks, it builds!
I got this now (at launch of "GameEngine" in Demo/Bin/Release, is that what I 
should launch?): 
GameEngine: brw_eu.h:187: brw_reg: Assertion `nr < 128' failed.
Abandon

Ok, this is a classical problem with shaders, i have to make something to fix 
this, its an error compiling shaders on low-end cards (most of them Intel).

You can surely fix it by searching for IgnoreShaderSupport in 
Resouces/Scripts/GameGUI.cfg  and settign it to 0.

    System = "GameGUI"
    Class = "Render"
    Name = "Render"
    Data
    {
        IgnoreShaderSupport=0
        PrecompileShaders=0
    }



Sorry :(

Sorry i mean, changing it to 1 


    System = "GameGUI"
    Class = "Render"
    Name = "Render"
    Data
    {
        IgnoreShaderSupport=1
        PrecompileShaders=0
    }
