| I request opengl3 in fltk2/fltk.
The patch adds basic opengl3 context creation to fltk2 linux, and it works for me.
My suggestion is to add 2 new modes (no driver support for these yet) for the mode() function
OPENGL3_FORWARD_COMPATIBLE
OPENGL3_DEBUG
And by default enable opengl 3 if it's available. | |

| Is there an #ifdef that can be used to compile the old code if the OpenGL headers don't define these functions? | |

| #3 | indy2718

| The patch already contains the needed typedefs except for GLXFBConfig.
glext.h should have a macro of GL_VERSION_3_0, and the glxext.h currently does not define the needed function prototypes. | |

| The Fl_Gl_Choice.cxx line 248 contains a printf("Success!\n"). I didn't add that in the patch. Please remove it.
if (glXGetFBConfigFromVisualSGIX && glXCreateContextAttribsARB) {
printf("Success!\n"); | |

| Please note: Although this is (currently) classified as 1.4-feature, the supplied patch (which is written for FLTK 2) has been applied to FLTK 2 with some small modifications (including the mentioned printf) in svn -r 6511 (OpenGL/Fl_Gl_Choice.cxx).
We should look at this when someone considers this for FLTK 1.x. | |

| Thanks. Can someone please delete line 248 of OpenGL/Fl_Gl_Choice.cxx in fltk 2 (svn HEAD)
printf("Success!\n"); | |

| Done (commented out in svn -r 6671). | |

| Fixed in Git repository.
As written above, the request regarding FLTK 2 was fulfilled.
FLTK 1.4 (git master) supports OpenGL 3, hence this STR can be closed.
Please see documentation or ask in fltk.general if there are questions.

If there is still need for a patch to add more OpenGL 3 functionality then fltk.coredev is the place to discuss this.
