I will keep this thread updated with links to MacOS X builds of the SDK.

Horde3D-1.0.0-beta1-osx

Known issues:
Chicago and Knight samples render incorrectly on NVidia 8800 GTS (and possibly others). Issue appears to be related to the AMBIENT shader contexts of skinning.shader.xml and parallax.shader.xml.

I've been having a lot of trouble running Horde on my system ever since the 0.1.15. With 1.0 betas, it's gotten worse. I've tried (unsuccessfully) figuring it out.. When I try to run any of the samples (as of svn r34), they crash at startup:

Code:

From what I could gather from debugging, all the pointers seem valid and everything should work but... Obviously something is wrong. When commenting out the TextureCube resource type registration, like so:

Code:

      /* Modules::resMan().registerType( ResourceTypes::TextureCube, "TextureCube", TextureCubeResource::initializationFunc,
         TextureCubeResource::releaseFunc, TextureCubeResource::factoryFunc ); */

The samples run but the cubemapping doesn't work. Terrain sample works fine without cubemapping, though. This is on top of the previous issues I've already been having..

Looks like you have driver issues with cubemaps - is this also affecting any commercial games? They are all running perfectly on my ATI card (although I haven't tried the latest from SVN.

Only 3d game I have on the mac side is quake3, and it works fine.

I do not think q3 uses cubemaps.
edit: http://svn.icculus.org/quake3/trunk/cod ... iew=markup no cubemaps

Grab the Unreal Tournament 2004 Demo. Pretty sure they use cubemaps for all the environments.

Sharp eyes there! Ja, looks as though we need a fallback to software mipmap generation as well.

Vurlix · **Joined:** 19.03.2008, 01:22 **Posts:** 79

Seems so. Horde *does* work with mipmaps disabled.

Or Nvidia could just fix their broken drivers! :twisted:

Ja, fat chance of that - especially if they haven't fixed the problem on Windows yet

Anyway, here's a small patch to make horde svn r35 build on OSX. This should go into the main source tree.

Thanks for that, I commited it with some slight adjustments.

Ok, I just got the SVN head building on Mac. No real troubles, except for troubles with GLFW and paths - I will get a patch together soon.
Ignore the patch previously in this message, it was over complex.

swiftcoder · **Posted:** 07.07.2008, 00:52

Here is a correct patch for the generatePath() function in the main.cpp of each sample. This does not require a patched GLFW, and can be applied directly to the SVN head.

Code:

string generatePath(char p[], const string& file) {
#ifdef __APPLE__
   string s(p);
   for (int i = 0; i < 4; i++)
      s = s.substr(0, s.rfind("/"));   
   return s + "/" + file;
#else
    const string s( p );
    if ( s.find("/") != string::npos) {
        return s.substr( 0, s.rfind( "/" ) ) + "/" + file;
    } else if ( s.find("\\") != string::npos ) {
        return s.substr( 0, s.rfind( "\\" ) ) + "\\" + file;
    } else {
        return file;
    }
#endif
}

Rationale: Mac argv[0] looks like this '/Applications/Knight.app/Contents/MacOS/Knight', so we have to strip off 4 slashes to get the actuall parent directory. This is because Mac applications are actually directories disguised as files.

Thanks for the patch. I integrated it into the SVN.
