OpenGL Did anyone mange to compile OpenGL under Cygwin?

Recommended Posts

Hello! I'm wondering whenever someone managed to acctualy build and OpenGL program under cygwin? The thing is, I would like to "fake" X11 functionality under Windows XP not needed to go into Linux, but the I couldn't build the simplest NeHe samples. Of course, my cygiwin installation X server is installed and working (glut exe/binary samples do work!) but I would like to create my own window and display some OpenGL graphics. Thank you in advance!

Hey!

I am not sure why you would want to do something like that. OpenGL does work under Windows right away.
Seriously if you want to develop something, a rat tail like that will get into your way. I would suggest you to install a decent ide like Microsoft Visual Studio Express (that´s probably the easiest to setup and I believe that the compiler is great) and then fetch the SDL libraries (www.libsdl.org).
The SDL will take care of window creation platform independently and will also work with X11 perfectly (MacOSX also). There should be plenty of tutorials to setup MSVC Express (which is free) with OpenGL/SDL.

Hope that helps a bit - always try to keep things simple ;-)

I'm confused as to why you would want to compile OpenGL - an interface to graphics card drivers that usually is closed-source. Do you mean compile a program that *uses* OpenGL? Since that is a very different matter.

And regardless of what you're compiling, give us errors and any necessary source files.

I agree with Frederick about using SDL.

No no.

I would just like to write a cross platform compatible mini framework. I don't want to switch between linux and windows. If a NeHe OpenGL sample application compiles under cygwin it will most probably also under Linux.

I don't want to use glut because it sets me limits.

You'll have to use either glut or wgl for using opengl under windows. And because wgl is windows only (afaik) you'll have to make separate code for linux.

The only other way is to use glut or anything similar.

And what limits are you referring too? There are solutions for limits with framebuffer types and list sharing.

Argh. Nobody understands me.

I would like to run the code for window creation under Xserver. I don't want to call WINAPI instead I would like to use the Xlib functions for window creation and handling. It is not ment to be a pure win32 application.

For the win32 part I will use a different codepath.

I think everyone understands that, but the question is why? There are countless cross-platform windowing toolkits that handle pretty much everything; about the only case when you need to implement your own is if you need advanced multi-monitor support.

I have several times for a number of years.

Without any details, it is impossible for me to speculate what you did wrong.

I highly recommend posting to cygwin-xfree at cygwin dot com. You are much more likely to get a useful response there.

Just use SDL. Then you don't have to have separate code paths for Windows and Linux, plus you get Mac and many other platforms for "free".

      Hello! As an exercise for delving into modern OpenGL, I'm creating a simple .obj renderer. I want to support things like varying degrees of specularity, geometry opacity, things like that, on a per-material basis. Different materials can also have different textures. Basic .obj necessities. I've done this in old school OpenGL, but modern OpenGL has its own thing going on, and I'd like to conform as closely to the standards as possible so as to keep the program running correctly, and I'm hoping to avoid picking up bad habits this early on.
      Reading around on the OpenGL Wiki, one tip in particular really stands out to me on this page:
      For something like a renderer for .obj files, this sort of thing seems almost ideal, but according to the wiki, it's a bad idea. Interesting to note!
      So, here's what the plan is so far as far as loading goes:
      Set up a type for materials so that materials can be created and destroyed. They will contain things like diffuse color, diffuse texture, geometry opacity, and so on, for each material in the .mtl file. Since .obj files are conveniently split up by material, I can load different groups of vertices/normals/UVs and triangles into different blocks of data for different models. When it comes to the rendering, I get a bit lost. I can either:
      Between drawing triangle groups, call glUseProgram to use a different shader for that particular geometry (so a unique shader just for the material that is shared by this triangle group). or
      Between drawing triangle groups, call glUniform a few times to adjust different parameters within the "master shader", such as specularity, diffuse color, and geometry opacity. In both cases, I still have to call glBindTexture between drawing triangle groups in order to bind the diffuse texture used by the material, so there doesn't seem to be a way around having the CPU do *something* during the rendering process instead of letting the GPU do everything all at once.
      The second option here seems less cluttered, however. There are less shaders to keep up with while one "master shader" handles it all. I don't have to duplicate any code or compile multiple shaders. Arguably, I could always have the shader program for each material be embedded in the material itself, and be auto-generated upon loading the material from the .mtl file. But this still leads to constantly calling glUseProgram, much more than is probably necessary in order to properly render the .obj. There seem to be a number of differing opinions on if it's okay to use hundreds of shaders or if it's best to just use tens of shaders.
      So, ultimately, what is the "right" way to do this? Does using a "master shader" (or a few variants of one) bog down the system compared to using hundreds of shader programs each dedicated to their own corresponding materials? Keeping in mind that the "master shaders" would have to track these additional uniforms and potentially have numerous branches of ifs, it may be possible that the ifs will lead to additional and unnecessary processing. But would that more expensive than constantly calling glUseProgram to switch shaders, or storing the shaders to begin with?
      With all these angles to consider, it's difficult to come to a conclusion. Both possible methods work, and both seem rather convenient for their own reasons, but which is the most performant? Please help this beginner/dummy understand. Thank you!

      I want to make professional java 3d game with server program and database,packet handling for multiplayer and client-server communicating,maps rendering,models,and stuffs Which aspect of java can I learn and where can I learn java Lwjgl OpenGL rendering Like minecraft and world of tanks

      A friend of mine and I are making a 2D game engine as a learning experience and to hopefully build upon the experience in the long run.

      -What I'm using:
          C++;. Since im learning this language while in college and its one of the popular language to make games with why not.     Visual Studios; Im using a windows so yea.     SDL or GLFW; was thinking about SDL since i do some research on it where it is catching my interest but i hear SDL is a huge package compared to GLFW, so i may do GLFW to start with as learning since i may get overwhelmed with SDL.  
      -Questions
      Knowing what we want in the engine what should our main focus be in terms of learning. File managements, with headers, functions ect. How can i properly manage files with out confusing myself and my friend when sharing code. Alternative to Visual studios: My friend has a mac and cant properly use Vis studios, is there another alternative to it?

      Both functions are available since 3.0, and I'm currently using `glMapBuffer()`, which works fine.
      But, I was wondering if anyone has experienced advantage in using `glMapBufferRange()`, which allows to specify the range of the mapped buffer. Could this be only a safety measure or does it improve performance?
      Note: I'm not asking about glBufferSubData()/glBufferData. Those two are irrelevant in this case.

      Before using void glBindImageTexture(    GLuint unit, GLuint texture, GLint level, GLboolean layered, GLint layer, GLenum access, GLenum format), does need to make sure that texture is completeness.
