LoadFunctions() causes Unhandled Exception

[HunterAP]

I just started using the OpenGL SDK, and have been running into an issue. Even with a basic project, I am getting an unhandled exception when the LoadFunctions() method is called.

I have followed the debug trail to the ParseVersionFromString() method.

The value for (const char*)_funcptr_glGetString(GL_VERSION)) is being passed in as NULL.

A seemingly valid pointer is being returned from IntGetProcAddress("glGetString");
_funcptr_glGetString 0x59a93ced {opengl32.dll!_glGetString@4} const unsigned char * (unsigned int) *

I'm using Visual Studio 2012 on Windows 7 64 bit. I'm compiling the library as a 32bit static, and I've tried both release and debug configurations.

Here's my source: (the includes are within < > blocks, but the code highlighting doesn't seem to like that)

#include "glload\gl_3_3.hpp"
#include "glload\gl_load.hpp"

#pragma comment(lib, "opengl32.lib")
#pragma comment(lib, "glloadD.lib")

int main()
{
    glload::LoadFunctions();
};

Any help would be appreciated.

Not sure if you solved this already, but you need a OpenGL context for LoadFunctions() to work. So open a window for your platform, open a gl context for this window and then call glload::LoadFunctions();

hope it helps,
