executable fails to find glTexImage3D on Mac OS.

see http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Number=250375
"...look for GL_VERSION >= 1.2, and use the core function glTexImage3D() instead."

  • Hi there,

    Thank you for trying OpenCity. Could you call opencity with the switch -glv then upload the output here, please ? OpenCity's command line version may need the switches -cd and -dd. You can also call opencity with --help switch for more information.

    Thank you.

  • Hi there,

    I'd like to have more information concerning your video driver and video card. It would help me for future development, that's why I asked you to call opencity with the -glv switch.

    Btw, your patch is already in the trunk. There's also 0.0.6.4stable release out there which contains that piece of code.

    Thanks

    hi, posting few lines from at the beginning, considering its a big one; hope this provides sufficient information on OpenGL on the system.
    regards,
