libgl and libglu seem to be installed correctly.. I can compile with those libs at gcc.. So there really maybe a problem with the configure script. Can I maybe download the GtkGlExt lib as binaries?

RE: OpenGL and cygwin
Dear Jurg, From that description: we are using cygwin on windows 7 on a DELL M4500 to remotely connect HP Z800 linux-pc via network. So on the linux-pc we use CAE applications with graphics over network. What can I do to improve the graphics performance via network? I understand that your graphics are displayed via Cygwin's X-server. If they use OpenGL, you should use the very latest version of that server, which just received hardware acceleration for OpenGL graphics. You can read about it at: http://cygwin.com/ml/cygwin-xfree/ Please note that I do not maintain any package relating to OpenGL on the X-server, so if you have any question, you should direct it to the list (cygwin-xfree at cygwin.com).

OPENGL ON CYGWIN
Hi, My name is Loren Greenman, and I am running Cygwin at home. When I log in remotely (secure shell) to the computers at where I work, I am unable to run application that require OpenGL. I have downloaded the OpenGL library, and am otherwise up to date on Cygwin. However, I still get an error that says OpenGL not available whenever I try to use this program. My graphics card has OpenGL capabilities, and when I run a OpenGL test program from Cygwin it works, but when I try it after remotely logging into another computer I am unable to use this program. Any help is greatly appreciated. Loren Greenman

Loren, Considering the message that made it to the list just before yours (http://cygwin.com/ml/cygwin-xfree/2004-07/msg00074.html), the choice of ALL-CAPS for the subject was perhaps not the wisest... :-) More below.

Any help is greatly appreciated. Loren Greenman I believe you're confusing the native OpenGL support (which you get from the opengl package) and the OpenGL/GLX extension for the X server. The OpenGL test program is most likely running using the native OpenGL. For the remote program to use OpenGL, you'll need to have the GLX extension enabled in the X server. While from what I recall it is already working (see http://cygwin.com/ml/cygwin-xfree/2004-03/msg00323.html), you'll need to post the exact error message you're getting and the exact commands you used to invoke your XWin session and the failing program. You might also be asked later to post /tmp/XWin.log from a failed session. Igor P.S.

OpenGL and cygwin
Hi all, I have been trying for the last few days to recreate some of the OpenGl problems that I have been asking the list about. Fortunately (or unfortunately, depending on one's perspective :)), I have been unable to get the errors reproduced in a standalone form, and in fact many of my OpenGL programs, even those that use more advanced features of OpenGL 1.3+, are working fine. Thanks a lot to Andre, Brian and CGF for helping out.

Re: OpenGL and Cygwin
My g++ command line is g++ -mno-cygwin -lglut32 -lglu32 -lopengl32 and a cygcheck on my exe file indicated that the glut file being linked is my local copy that I got from nvidia, Can you tell us why you are using GLUT from NVDIA instead of GLUT from Cygwin's OpenGL package? The reason I was using Nvidia's glut is because they have a more recent version of it (glut 3.7 I believe) than the stated version that cygwin provides. I recognize that this may cause weird unsupported problems, so I tried both versions, and get the same behaviour (success/failure) whichever one I use. As for using extgl to do dynamic loading, that works fine: I now can successfully compile my code. It still doesn't run :), but given the complexity of the program I am running, I am not sure where exactly the problem is or if it is a cygwin error.

Do the nvidia extensions headers you downloaded include gl.h ? If yes,
that could be your problem.
However, I have severe problems when linking using g++ *.o -lglu32
-lglut32 -lopengl32 (as per the /usr/doc/opengl*/README file).
/usr/doc/opengl*/README says:
Add -lglut32 -lglu32 -lopengl32 to your link command (in that order).
Most of the

A sign that I am probably missing some more basic libs is that I even get

Hi, I apologize in advance if this duplicates questions already asked and answered: I have searched the cygwin/cygwin-apps mailing lists already, and there appears to be no clear answer, and most of the FAQs are a bit outdated. I have an opengl program that I wish to compile under the cygwin environment, but using NO mesa drivers, only the native windows drivers. This program uses GLU and GLUT, as well as opengl and nvidia extensions. Now I have downloaded the nvidia extensions headers, and am able to create object files correctly, after some experimenting (it appears that I need to use the -mno-cygwin flag to enable the _WIN32 macros). However, I have severe problems when linking using g++ *.o -lglu32 -lglut32 -lopengl32 (as per the /usr/doc/opengl*/README file). Most of the stubs cannot be found. A sampling of the errors I get: undefined reference to [EMAIL PROTECTED] undefined reference [EMAIL PROTECTED] A sign that I am probably missing some more basic libs is that I even get undefined references to __assert, as well as something mysterious called __imp__iob, which again looks like somethng unrelated to the opengl code I am compiling.

Re: opengl and cygwin
Hi, I have been working OpenGl and Cygwin for some time now. You do not have to install xfree in order to make it work. Just download the Package : http://atlas.puj.edu.co/~amatta/tesis/OpenGl/Windows/cygwin/OpenGLPackage.zip It includes all the necesary libraries to make OpenGl and Cygwin work together. Antonio. Is there any reason that you don't use the OpenGL package from the Cygwin's distribution ? Every necessary pieces is there, and you also get GLU, GLUT and GLUI on top of that.

opengl and cygwin
this seems like an X question, but it concerns openssh as well, so I am going to ask. okay, I need to do some opengl development. I found that opengl library comes with cygwin, that's a plus for me. but I think I might need to install xfree for cygwin in order for it to work (is this true?) say I need to install, but I don't want to. I have exceed, so, can I just run exceed, forward the DISPLAY, an expect anything to work at all? if I am talking non-sense here...can anyone tell me how to get opengl to work? since it's included in the cygwin package? (does it include glut? or do I have to compile / install it myself?) __ Do You Yahoo!? Send FREE Valentine eCards with Yahoo!

Re: opengl and cygwin
Thanks for that information. I read the info. If my understanding is correct, the opengl that came with cygwin is just like the one with windows and all I have to do is link. so I just added -llib to my gcc line...well, it returns symbol not found error...okay, that sounds to me that my lib PATh is incorrect...so I tried to look for the file like glut.lib...that came up empty...so can anyone ever played with opengl on cygwin tell me how should I link? what PATH do I need to add? --- Larry Hall (RFK Partners, Inc) [EMAIL PROTECTED] wrote: At 03:03 PM 2/5/2002, Ling F.

Re: opengl and cygwin
Cygwin follows UNIX conventions for library names. That means the glut library is named libglut.a. If you installed the OpenGL package, you should find this in /usr/lib.
