and I'm not sure about the html error maybe it's a xss vuln

Maybe post the error?

You're using the wrong overload. Try:

clCompileProgram(
    program,
    platforms[0]._devices,
    "",//options
    (PointerBuffer)null,//input header
    null,//header include name
    pfn_notify,
    MemoryUtil.NULL
);
I may end up removing the other overloads, they're indeed confusing.

You're using the wrong overload. Try:

Thanks that got it working
