Such things tend to happen when you try to use Win32-specific code on Linux.
Look here (https://www.opengl.org/wiki/Programming_OpenGL_in_Linux:_GLX_and_Xlib).

Define «without».
What GUI toolkit do you want to use? Is it GTK+ (http://andrewboktor.googlecode.com/svn/trunk/gaspaint/examples/gtkglext-example.c) or Qt (http://doc.qt.io/qt-4.8/qt-opengl-hellogl-example.html)?
Is there any graphic environment at all? If no, then use OpenGL ES over DRI (http://virtuousgeek.org/blog/index.php/jbarnes/2011/10/31/writing_stanalone_programs_with_egl_and_).
