FSRC should look like this:
FSRC=: {{)n
#version $version
$f_in $lowp vec4 v_color;
$fragColor;
void main(void) {
$gl_fragColor= v_color;
}
}}
The names with preceding $ characters are not used literally -- they
are replaced in a fashion which depends on your machine's GLSL and
GLES_VERSION. In your case, '$gl_fragColor' becomes 'fragColor'. (See
the 'fixversion' verb for details.)
Anyways, ... I'll email you an instrumented copy of the script.
Thanks,
