“Undefined reference to _ms_vsnprintf”

Question

I figured out what I did. It was one of the libraries I was using. It had a reference to _ms__vsnprintf that wasn't defined in it. I removed the file and my program compiled. Thanks for your help. For future reference, the file was libglfw3.a .

How do I fix the error "Undefined Reference to _ms_vsnprintf"? I've only seen one other post about it, and that didn't fix my problem. I'm using Windows 8, Code::Blocks and MinGW. This is my code.

#define __LCC__
#define GLEW_STATIC
#define GLFWAPI __declspec(dllimport)
#include <stdio.h>
#include <stdlib.h>
#include <GL/glew.h>
#define GLFW_INCLUDE_GLU
#include <GL/glfw3.h>
#include <glm/glm.hpp>
using namespace glm;
int main() {
if( !glfwInit() ) {
    fprintf( stderr, "Failed to initialize GLFW\n");
    return -1;
}
 glfwWindowHint(GLFW_SAMPLES, 4);
 glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
 glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
 glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);

GLFWwindow* window;
window = glfwCreateWindow( 600, 800, "OpenGL Window", NULL, NULL);

if(window == NULL) {
    fprintf(stderr, "OpenGL Couldn't open the window.\n");
    glfwTerminate();
    return -1;
}

glfwMakeContextCurrent(window);
glewExperimental=true;
if (glewInit() !=GLEW_OK) {
    fprintf(stderr, "Failed to start GLEW.\n");
    return -1;
}
 }

Here's the build log from Code::Blocks

Answer 1

I edited the question with my answer. Deleting libglfw3.a fixed it.
