Hey guys, I've been using C++ with various environments (MSVC++, Dev C++, Notepad++, Bluefish + command line) and I want to start doing 3d graphics. I've heard the best way to do this is with openGL, now I know there's a good tut on this site for openGL, but I have a few questions Right now I'm using Bluefish on Ubuntu, so where can I get glut for linux? Will my programs still compile on Windows if i write them in Linux? If 1 or 2 is a "no" then which Windows environment would you guys recommend? (MSVC++ or Dev C++)? thanks, Drew |

I'd like this too, I want to try Ruby with OpenGL. |

If you write in the portable subset of C++, you can get it to compile on both Windows and Linux. If you're careful, you can probably get OSX too. Cross-compiling is a chore, though, so be forewarned. You will need to compile for the target OS, which is probably best done ON that OS, with a compiler built for that platform. No idea about GLUT though. My OpenGL stuff has all been through JMonkeyEngine on LWJGL. Does Ruby even *have* OpenGL bindings? |

If not, remove the 3 from there. saltpro15 @ Thu Mar 26, 2009 6:06 pm wrote: Will my programs still compile on Windows if i write them in Linux? Yes, before the GLUT and OpenGL include files you need to include the Windows API header. The following (from memory) should do the trick.
That should include the Windows API header only if you're compiling under Windows. saltpro15 @ Thu Mar 26, 2009 6:06 pm wrote: If 1 or 2 is a "no" then which Windows environment would you guys recommend? (MSVC++ or Dev C++)? Personally I found Dev-C++ to be easiest on Windows. You install the OpenGL/GLUT package for it from the package manager. |

I decided to go with Dev C++, found the file for glut, installed it, ran some sample code and I'm getting linker errors, anyone know what I did wrong? |

The libraries may not be on the LD_LIBRARY_PATH or similar. I'll assume you got the glut libraries through the repositories; can we see your linker errors? |

Are you new to graphical APIs? If you are then I wouldn't recommend jumping right into openGL. Begin with SDL first, it's simple, but it only does 2D. On the plus side you can use SDL with openGL instead of using GLUT. |

I forget exactly now, haven't done any OpenGL in a while. |
