This is a Cygwin/XFree86 DRI question from: Timothy A. Holt Boeing, Seal Beach, CA.
I down loaded Cygwin/XFree86 on Jan 21 2003 onto a DELL x86-based PC for the purpose of compiling and running OpenInventor Programs. I got the OpenInventor built and compiled with their examples and my own code, but noticed that it wasn't using DRI hardware acceleration. I've been reading README.DRI and README.DRIcomp and tried some of the checks it said to do. xdpyinfo showed: XFree86 version 4.2.0 but did not show XFree86-DRI extension glxinfo showed: direct rendering: No OpenGL renderer string: Mesa GLX Indirect My GL library is named libGL.a in the /usr/X11R6/lib when I do: strings libGL.a | grep DRI I don't see any XF86DIR things... there are some _DRI_glxUseXFont kind of things. There is no XF86Config file any where, and no /usr/X11R6/lib/modules directory either. Question: does this mean I need a different GL ? I thought that the XFree86 GL had the DRI. Do I have to do all these steps in README.DRIcomp to get DRI to work ? I'm a graphics programmer working most of the time on SGI UNIX workstations. We want to port some things to the PC; we have, using Exceed 3D, but would like to try with the Cygwin. My program runs with Cygwin now, but has problems with Z buffer, slow texture mapping, and sometimes slow to redraw window after resize or move. Also crashes when trying to popup the OpenInventor SoXtMaterialEditor from my program. Thanks for any help tim
