Hi,

I used glfw for Windows Vista and it worked perfectly. Now I switched  
to Ubuntu 8.04 and want to continue develop under this platform.  
But I am not able to compile my programs with glfw…I am new to Linux ☹

Here are some Infos, which will maybe help you to help me 🙂

- downloaded glfw 2.6 source

- installed newest nvidia-driver (NVIDIA-Linux-x86-173.14.05-pkg1)

- installed the package "libglu1-mesa-dev" (For the GLU-Library)

- Then I created the shared and static glfw library with:  
sudo make x11  
sudo make x11-install

- All worked fine: Now I have the following important libs and Headerfiles:

```
/usr/include/GL ls
	glext.h gl.h gl\_mangle.h glu.h glu\_mangle.h glxext.h glx.h glx\_mangle.h

/usr/local/lib ls
	libglfw.a

```

- When I type glxinfo all seems ok:  
/usr/local/lib glxinfo  
name of display: :0.0  
display: :0 screen: 0  
direct rendering: Yes  
server glx vendor string: NVIDIA Corporation  
server glx version string: 1.4  
…  
…  
GLX version: 1.3  
…  
…  
OpenGL vendor string: NVIDIA Corporation  
OpenGL renderer string: GeForce 8500 GT/PCI/SSE2  
OpenGL version string: 2.1.2 NVIDIA 173.14.05

- Then I wrote some sample Test Programm called test.c:

//\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*

#include \<stdlib.h\> // For malloc() etc.  
#include \<stdio.h\> // For printf(), fopen() etc.  
#include \<math.h\> // For sin(), cos() etc.  
#include \<GL/glfw.h\> // For GLFW, OpenGL and GLU

void Draw( void )  
{  
int width, height; // Window dimensions  
double t; // Time (in seconds)

```
// Get current time
t = glfwGetTime\(\);

  // Get window size
  glfwGetWindowSize\( &amp;width, &amp;height \);

  // Make sure that height is non-zero to avoid division by zero
  height = height &lt; 1 ? 1 : height;

  // Set viewport
  glViewport\( 0, 0, width, height \);

  // Clear color and depht buffers
  glClearColor\( 0.0f, 0.0f, 0.0f, 0.0f \);
  glClear\( GL\_COLOR\_BUFFER\_BIT | GL\_DEPTH\_BUFFER\_BIT \);

  // Set up projection matrix
  glMatrixMode\( GL\_PROJECTION \); // Select projection matrix
  glLoadIdentity\(\); // Start with an identity matrix
  gluPerspective\( // Set perspective view
      65.0, // Field of view = 65 degrees
      \(double\)width/\(double\)height, // Window aspect \(assumes square pixels\)
      1.0, // Near Z clipping plane
      100.0 // Far Z clippling plane
  \);

  // Set up modelview matrix
  glMatrixMode\( GL\_MODELVIEW \); // Select modelview matrix
  glLoadIdentity\(\); // Start with an identity matrix
  gluLookAt\( // Set camera position and orientation
      0.0, 0.0, 10.0, // Camera position \(x,y,z\)
      0.0, 0.0, 0.0, // View point \(x,y,z\)
      0.0, 1.0, 0.0 // Up-vector \(x,y,z\)
  \);

  // Here is where actual OpenGL rendering calls would begin...

```

}

int main( int argc, char \*\*argv )  
{  
int ok; // Flag telling if the window was opened  
int running; // Flag telling if the program is running

```
  // Initialize GLFW
  glfwInit\(\);

  // Open window
  ok = glfwOpenWindow\(
      640, 480, // Width and height of window
      8, 8, 8, // Number of red, green, and blue bits for color buffer
      8, // Number of bits for alpha buffer
      24, // Number of bits for depth buffer \(Z-buffer\)
      0, // Number of bits for stencil buffer
      GLFW\_WINDOW // We want a desktop window \(could be GLFW\_FULLSCREEN\)
  \);

  // If we could not open a window, exit now
  if\( \!ok \)
  \{
      glfwTerminate\(\);
      return 0;
  \}

  // Set window title
  glfwSetWindowTitle\( &quot;My OpenGL program&quot; \);

  // Enable sticky keys
  glfwEnable\( GLFW\_STICKY\_KEYS \);

  // Main rendering loop
  do
  \{
      // Call our rendering function
      Draw\(\);

      // Swap front and back buffers \(we use a double buffered display\)
      glfwSwapBuffers\(\);

      // Check if the escape key was pressed, or if the window was closed
      running = \!glfwGetKey\( GLFW\_KEY\_ESC \) &amp;&amp;
                glfwGetWindowParam\( GLFW\_OPENED \);
  \}
  while\( running \);

  // Terminate GLFW
  glfwTerminate\(\);

  // Exit program
  return 0;

```

}  
//\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*

- For the compiling I used the following command:

gcc test.c -o test.exe -lglfw -lGL -lGLU -lX11 -lpthread -lm

- then I got this ☹

What I have done wrong ?

I have tried also tried to install the package "libxrandr-dev" but I had also the newest version already installed.

Can somebody plz help me to set the correct compile-Parameter ?

thanx und greetz

Hey…no I have solved it 🙂

The right command-line is the following 🙂 I forgot the -lxandr 🙂

gcc test.c -o test.exe -lglfw -lGL -lGLU -lX11 -lpthread -lXrandr -lm

Thanx and Greetz
