Answer 1

Using the accepted answer above, but for newer versions of cocos2d:

In CCShader.m replace the lines

static GLint
CompileShaderSources(GLenum type, NSArray *sources)
{

with

#define EXTENSION_STRING "#extension GL_OES_standard_derivatives : enable"
static NSString * g_extensionStr = @EXTENSION_STRING;

static NSArray * PrependExtensionIfNeeded(NSArray *sources)
{
    NSMutableArray *mutableSources = [NSMutableArray array];

    BOOL hasExtension = NO;

    for (NSString *source in sources)
    {
        NSString *newSource = [source copy];
        if([source rangeOfString:g_extensionStr].location != NSNotFound)
        {
            hasExtension = YES;
            NSArray *strs = [source componentsSeparatedByString:g_extensionStr];
            newSource = [strs componentsJoinedByString:@"\n"];
        }

        [mutableSources addObject:newSource];
    }

    if (hasExtension)
    {
        NSMutableString *firstSource = [NSMutableString stringWithString:[mutableSources firstObject]];
        [firstSource insertString:[NSString stringWithFormat:@"%@\n", g_extensionStr] atIndex:0];
        [mutableSources replaceObjectAtIndex:0 withObject:firstSource];
    }

    return mutableSources;
}

static GLint
CompileShaderSources(GLenum type, NSArray *sources)
{
    sources = PrependExtensionIfNeeded(sources);
