ImGui Docking giving me only 3 linking errors for 3 particular functions. ImGui Master runs fine.

As seen in the screenshot, these are the 3 linking errors that I am getting. Kindly let me know what can be the reason for this and how to fix it.

The only reason i can think of is that you are having a recent version of glfw in your include path but linking an older version (eg the one bundled with dear imgui examples).

Thank you @ocornut for pointing it out to me. I downloaded the glfw 3.3.4 version, updated the necessary files, and sure enough its fixed now and working. Thanks again!!

Just fixed that on my side too ... glfw3.lib was stale ...

[ocornut]

To clarify, we normally do NOT use those symbols in older GLFW versions:

#define GLFW_HAS_WINDOW_ALPHA         (GLFW_VERSION_MAJOR * 1000 + GLFW_VERSION_MINOR * 100 >= 3300) // 3.3+ glfwSetWindowOpacity
#define GLFW_HAS_PER_MONITOR_DPI      (GLFW_VERSION_MAJOR * 1000 + GLFW_VERSION_MINOR * 100 >= 3300) // 3.3+ glfwGetMonitorContentScale
#define GLFW_HAS_MONITOR_WORK_AREA    (GLFW_VERSION_MAJOR * 1000 + GLFW_VERSION_MINOR * 100 >= 3300) // 3.3+ glfwGetMonitorWorkarea

#if GLFW_HAS_MONITOR_WORK_AREA
        glfwGetMonitorWorkarea(glfw_monitors[n], &x, &y, &w, &h);
...

#if GLFW_HAS_PER_MONITOR_DPI
        glfwGetMonitorContentScale(glfw_monitors[n], &x_scale, &y_scale);
...

#if GLFW_HAS_WINDOW_ALPHA
static void ImGui_ImplGlfw_SetWindowAlpha(ImGuiViewport* viewport, float alpha)
{
    ImGui_ImplGlfw_ViewportData* vd = (ImGui_ImplGlfw_ViewportData*)viewport->PlatformUserData;
    glfwSetWindowOpacity(vd->Window, alpha);
}
#endif

So this can only happen if the HEADERS and linked library are not matching.
