Question

I am trying to setup OpenGL developing environment on Ubuntu.I installed all the libs including GLFW as I don’t want to use GLUT.GLEW lib has been installed too.I am trying to set it all in NetBeans.I have never used it before and currently I am getting :

undefined reference to `glfwInit’ error while running this simple code:

#include <stdio.h>
#include <cstdlib>
#include <iostream>
#include <GL/glew.h>
#include <GL/glfw.h>
#include "glm.hpp"
using namespace std;
using namespace glm;

int main(int argc, char** argv) {


 /*      init GLFW         */
    if(!glfwInit()){

        fprintf(stderr,"failed to init GLFW");

     }
    return 0;
}

I am sure it is linker related problem.So I have added libglfw.a to Linker->Libraries and then got even more errors like these:

make[2]: Entering directory /home/sasmaster/NetBeansProjects/OpenGLDemo'
mkdir -p dist/Debug/GNU-Linux-x86 g++ -o dist/Debug/GNU-Linux-x86/opengldemo build/Debug/GNU-Linux-x86/main.o /usr/lib/libglfw.a

What else should I link or install?

Update:
Here it is said one should add LIBRARIES=’-pthread -lglfw -lGL -lX11 -lGLU -lXxf86vm’
But where should I add those in NetBeans properties? I tried put into the MakeFile and “linker options” too and nothing helped.

Update1
Compiling the main.cpp manually using this command:

**g++ main.cpp  -o Game -lglfw -lGL -lGLU -lX11 -lpthread -lXxf86vm -lm**

Compiles fine.How do I link all these libs via NetBeans???

Answer 1

I figured out the solution.For those interested:
Openg Project properties.Then “Linker” ->“Libraries”.
In the Libraries dialog:
Click “Add Option” -> “Other Option”.
In the textfield insert these params:

-lGLEW -lglfw -lGL -lGLU -lX11 -lpthread -lXxf86vm -lm

I guess lGLU is needed only if you use the old OpenGL version.
