Segmentation fault when creating a window

Hi there,
I’m new to GLFW, and I’m having problems getting started.
I want to create an OpenGL ES application for desktop (yes, ES). I’m using 64-bit linux. I have a standard installation of GLFW 3.2. When I try to create a window using this code:

#include <GLFW/glfw3.h>
GLFWwindow* createWindow(uint16_t width, uint16_t height, const char* title)
    bool init = glfwInit();
    if (!init)
            return NULL;
    glfwWindowHint(GLFW_SAMPLES, 4);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 0);
    return glfwCreateWindow(width, height, title, NULL, NULL);

I get the following output:

GL renderer: [NVS 300/PCIe/SSE2]
GL vendor:[NVIDIA Corporation]
GL version: [3.3.0 NVIDIA 340.96]
GL shading language version: [3.30 NVIDIA via Cg compiler]
Segmentation fault (core dumped)

I think the problem is that I’m using NVidia driver 340.96, which does not support OpenGL ES. However, I have an OpenGL ES emulator - my own,, etc. Is there a way to make GLFW link/include these libraries (which as far as I can tell are the system default anyway)?

Thanks a lot!

Are you able to step through with a debugger to determine in which function+line the segfault occurs?

This is the output I get from gdb:

Program received signal SIGSEGV, Segmentation fault.

56        version = (const char*) window->context.GetString(GL_VERSION);

At this point, gdb says GL_VERSION and context have no symbol in the current context

Try it without setting GLFW_CONTEXT_CREATION_API.
