Hi, I'm getting this error when running make:

Is this a syntax error or something? For the record I'm using g++ 3.4 from Debian with the mesa libraries instead of xlibmesa-gl, running XOrg 6.9.

If you're ugin separate libraires you have to make sure that all include paths are correctly set. It seems to be something's missing here. Or maybe you'll even need some additional includes in the source.
BTW: Wiht pure Mesa you won't get hardware acceleration, so don't expect more then 3-4 FPS!

OK I'll try fixing that.

BTW: Yes I know, which is why I want to try out the software renderer! (BTW2: No I won't install *any* proprietary drivers, not because the drivers themselves are bad but because they're proprietary!)

OK, I changed the makefile and added the GL folder for includes.

Compiler command becomes g++ -c COpenGLDriver.cpp -o COpenGLDriver.o -I"include/" -I"zlib/" -I/usr/include -I/usr/include/GL -DIRRLICHT_EXPORTS=1 and still fails with the same errors.

Is there any way to skip the OpenGL libraries when compiling?

Thanks,
andrew

I figured out how to skip the GL option by editing IrrCompileConfig.h and it seems to compile, albeit without OpenGL.

thanks,

And now, after compiling it, the examples (using any of OpenGL, Irrlicht Software or Apfelbaum) complain that they cannot get visual. Is this something to do with X?

Did you apply all the Linux patches available on the patch page? Otherwise you won't be able to remove OpenGL completely. The standard Irrlicht uses some OpneGL methods to open the windows etc. Seems to be the case here.
And: No, you don't need the vendor drivers to use some hardware acceleration. The standard X drivers support a decent amount of hardware access. Thus, X.Org drivers should be much faster than the software rendered Irrlicht, or the software emulated OpenGL.

With the drivers: Yes, but not for nvidia cards - I know that older radeons and some others are supported directly by DRI. Anyway I want to get his working because I want to distribute a game to people who don't have hardware acceleration.

Patches: I'll try them.

Thanks anyway,
Andrew
