Re: Attempting to build

Thank you for you assistance. I really appreciate it. I made a few changes. I think that I'm doing what you are directing, but I am probably not.

Re: Attempting to build

I tried it with these options but I got the same results.

Code: Select all

# cmake .. -DCEGUI_BUILD_RENDERER_OPENGL=ON -DCEGUI_BUILD_RENDERER_OPENGL3=OFF -DCEGUI_USE_EPOXY=OFF -DCEGUI_USE_GLEW=ON
# make
# make install

Attempting to build

Hello, I'm attempting to use the Old desktop OpenGL 1.2 (Fixed Function) version of CEGUI. I'm building with plain old cmake .. make make install Does building for OpenGL 1.2 require any special options? The Desktop OpenGL 3.2 or OpenGL ES 2.0 version required some additional options during the buil...

Re: Failed to obtain desktop OpenGL version

I'm guessing then that my computer cannot support OpenGL greater than 3.0. It is an integrated Intel graphics card on a relatively old Dell. I ran another grep on glxinfo just to get everything related to OpenGL and this was the output. $ glxinfo | grep -i "Opengl" OpenGL vendor string: In...

Re: Failed to obtain desktop OpenGL version

No particular reason. I guess it is what installed when I typed "sudo yum install ....". What version of OpenGL do you recommend that I use? Should I try and go for OpenGL 4.3? I'm going for the path of least resistance right now because I'm not doing anything too fancy. Thank you again fo...

Re: Failed to obtain desktop OpenGL version

So, the reason why epoxy_gl_version() was returning zero was because OSG didn't set the only created context to the current context. I guess I assumed that since there was only one context that it would pick that context. I fixed that by setting it as the current context. viewer.realize(); viewer.ge...

Re: Failed to obtain desktop OpenGL version

Thank you for the clarification. I put some debugging code in my application and the integer returned by epoxy_gl_version() is '0' ( zero ). The function returning zero doesn't appear to crash the application, but it does appear that CEGUI won't accept zero as a valid version number. I'll write a sh...

Re: Failed to obtain desktop OpenGL version

#include <epoxy/gl.h> was already in the header file and it didn't cause any problems. It is only when I try to initialize CEGUI that I crash. The error given when I step through the debugger is: CEGUI::RendererException in function 'void CEGUI::OpenGLInfo::initTypeAndVer()' (/home/jay/tmp/cegui/ceg...

Re: Failed to obtain desktop OpenGL version

Just another data point, I just tried starting CEGUI the "hard way" with: cout << "Checkpoint 1" << endl; CEGUI::OpenGL3Renderer& myRenderer = CEGUI::OpenGL3Renderer::create(); cout << "Checkpoint 2" << endl; CEGUI::System::create( myRenderer ); cout << "Checkp...

Re: Failed to obtain desktop OpenGL version

Does this work? I adjusted my logic to call "CEGUI::OpenGL3Renderer& myRenderer = CEGUI::OpenGL3Renderer::bootstrapSystem();" on the 100th frame. So, my application launched. I moved around a little bit. I saw the scenery. Then, on the 100th frame it crashed with the same error. Please...

Re: Failed to obtain desktop OpenGL version

I finished downloading and installing the official version of Epoxy. I then rebuild CEGUI and my project. I continue to get the same errors.

I also tried the official development version for Fedora. It was the same.

Thank you again for taking the time to look into this with me,
Jay
