Windows  On Windows you need to include the gl h header for OpenGL 1 1 support and link against OpenGL32 lib  Both are a part of the Windows SDK  In addition  you might want the following headers which you can get from http   www opengl org registry      lt GL glext h gt  - OpenGL 1 2 and above compatibility profile and extension interfaces    lt GL glcorearb h gt  - OpenGL core profile and ARB extension interfaces  as described in appendix G 2 of the OpenGL 4 3 Specification  Does not include interfaces found only in the compatibility profile   lt GL glxext h gt  - GLX 1 3 and above API and GLX extension interfaces   lt GL wglext h gt  - WGL extension interfaces    Linux  On Linux you need to link against libGL so  which is usually a symlink to libGL so 1  which is yet a symlink to the actual library driver which is a part of your graphics driver  For example  on my system the actual driver library is named libGL so 256 53  which is the version number of the nvidia driver I use  You also need to include the gl h header  which is usually a part of a Mesa or Xorg package  Again  you might need glext h and glxext h from http   www opengl org registry   glxext h holds GLX extensions  the equivalent to wglext h on Windows   If you want to use OpenGL 3 x or OpenGL 4 x functionality without the functionality which were moved into the GL ARB compatibility extension  use the new gl3 h header from the registry webpage  It replaces gl h and also glext h  as long as you only need core functionality    Last but not the least  glaux h is not a header associated with OpenGL  I assume you ve read the awful NEHE tutorials and just went along with it  Glaux is a horribly outdated Win32 library  1996  for loading uncompressed bitmaps  Use something better  like libPNG  which also supports alpha channels

Debian Linux  e g  Ubuntu   sudo apt-get update OpenGL  sudo apt-get install libglu1-mesa-dev freeglut3-dev mesa-common-dev   Windows  Locate your Visual Studio folder for where it puts libraries and also header files  download and copy lib files to lib folder and header files to header  Then copy dll files to system32  Then your code will 100  run   Also Windows  For all of those includes you just need to download glut32 lib  glut h  glut32 dll

Some of the answers above  in regards to linux  are either incomplete  or flat out wrong  For example   usr include GL gl h is not part of    mesa-common-dev or has not been for many years  At any rate  for a more current answer  these two packages are important  https   mesa freedesktop org archive mesa-20 1 2 tar xz ftp   ftp freedesktop org pub mesa glu glu-9 0 1 tar xz The glu h is part of glu itself  GL glu h GL glu mangle h  Mesa is evidently significantly larger  Its headers are a bit variable  I suppose  depending on the flags given to meson  but should include these typically  KHR khrplatform h                                                                                                          EGL eglplatform h                                                                                                          EGL eglext h                                                                                                               EGL eglextchromium h                                                                                                       EGL eglmesaext h                                                                                                           EGL egl h                                                                                                                  vulkan vulkan intel h gbm h GLES3 gl31 h GLES3 gl3ext h GLES3 gl3 h GLES3 gl32 h GLES3 gl3platform h xa composite h xa tracker h xa context h GLES2 gl2 h GLES2 gl2platform h GLES2 gl2ext h GLES gl h GLES glplatform h GLES glext h GLES egl h GL gl h GL glx h GL osmesa h GL internal GL internal dri interface h GL glcorearb h GL glxext h GL glext h  Hope that helps anyone finding an answer this question in the future  compiling dosbox needs this  for instance  due to SDL opengl

If you re on Windows  they are installed with the platform SDK  or Visual Studio   However the header files are only compatible with OpenGL 1 1  You need to create function pointers for new functionality it later versions  Can you please clarify what version of OpenGL you re trying to use
