Någon som behöver en partner för uppgifterna?

Anyone needing a partner for the assignments?

Behöver du fortfarande en partner? I så fall samarbetar jag gärna!

If you are getting the RenderChimp code to work on OSX, check out Jacob's first reply on the 2013 forum.

Hej,
försöker få RenderChimp att fungera på OS X 10.9.4. Har installerat SDL och SDLimage efter vad som stod i forumet för 2013.

Jag får dock detta felmeddelandet "No architectures to compile for (ARCHS=x86_64, VALID_ARCHS=i386)."

Mina build settings i architecture är:

Additional SDKs:
Architectures: Standard Architectures (64-bit Intel) (x86_64)
Base SDK: Latest OS X (OS X 10.9)
Build Active Architecture Only: No
Supported Platforms: OS X
Valid Architectures: i386

Har googlat utan framgång så om någon vet vad som är fel får ni gärna hjälpa till!

Try setting architecture to 32-bit Intel (i386)
RC still has 32bit dependencies.

I changed that but got some new problems instead...
Here is a print screen of the error messages:

Hi!

Anyone needing a partner?

For OSX 10.9, you need to make the following changes.

In GLee.h replace :
           typedef ptrdiff_t GLintptrARB;
      typedef ptrdiff_t GLsizeiptrARB;
with :
           typedef long GLintptrARB;
      typedef long GLsizeiptrARB;
and replace :
   typedef int GLhandleARB;
with :
        typedef  void* GLhandleARB;

and in RendererGL.cpp add a cast to (GLint) for GL_VERTEX_SHADER and GL_FRAGMENT_SHADER
  id = (GLint) glCreateShaderObjectARB(GL_VERTEX_SHADER);

 id = (GLint) glCreateShaderObjectARB(GL_FRAGMENT_SHADER);

I changed that but got some new problems instead...

Hello.  I have downloaded SDL.frameworks version 1.2.15 and SDL_image.frameworks version 1.2.12 for mac OSX and put them both into my /Library/Frameworks folder.  I have also updated the changes mentioned above regarding Glee.h and GLint casting.  However now I am getting an error in PlatformOSX.cpp of "SLD_image/SDL_image.h" file not found.  I've tried to change this to simply SDL_image.h but it cannot find that file and I have tried renaming the SDL_image.h file in the SDL_image.frameworks but that doesn't work either.  Anyone else running MAC OSX 10.9.1 and Xcode 5.1.1 having the same problem or know how to fix it? thank you.

Seems like it works for me now so maybe this will solve the problem.

In the bar to the left with the file system, navigate to frameworks->linked frameworks. At first my "SDL_image.frameworks" was marked red and the path/location was wrong. So if this is the case then change the path/location to "/Library/Frameworks/SDL_image.framework". This can be done in the bar to the right when you mark "SDL_image.frameworks".

It shows it as a valid path. It should have Linked Frameworks->SDL_image.frameworks->Frameworks and Headers-> (in Headers) SDL_image.h and only this header.  This is what mine shows, is that correct?

I also need a partner if anyone else does. I'm a student at UCLA in California and I don't speak any Swedish.  My name is David Scheibe.

Hi!
I'm looking for a partner as well and also operate on OS X. Got mine to work after reading up in the forum, I could help you tomorrow after the lecture if don't get it to start. Because I had the same problem. If you are up for partnership my name is Kenan Sulejmanovic. I'm student of LTH
