template building errors with 1.8 xcode 4

[dowi]

hi

this is what i've done:

i downloaded 1.8 from Mercurial.
i followed the guide for building the source for iphone
downloaded the template for xcode 4

i get now 6 errors that says:

Code: Select all

Undefined symbols for architecture i386:
  "_CGDataProviderCreateWithData", referenced from:
      Ogre::EAGLWindow::copyContentsToMemory(Ogre::PixelBox const&, Ogre::RenderTarget::FrameBuffer) in libRenderSystem_GLESStatic.a(OgreEAGLWindow.o)

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

now, shouldn't it be armv6 instead of i386?

the only thread related i found was this:
http://www.ogre3d.org/forums/viewtopic.php?f=21&t=63831
but it didnt help to add the zlib

anyone can help?

Are you building for the simulator by any chance?

[dowi]

yeah, isnt it suppose to work?

after the dource build i have 3 lib folders:
Release
Release-iphoneos
Release-iphonesimulator


i tried changing the lib search path but no luck : - \

[dowi]

ok i'v built for device and now i get this errors (same except arvm6)

thanks alot for all the help

[masterfalcon]

Try adding the CoreGraphics framework in there too. I'll need to update the templates to account for that changes in copyContentsToMemory.

[dowi]

hi!!!

it's working now! build successfully for device and simulator!

had to add coreGraphics.framework
/*edit->*/ you precedded me : )
and the linking problems are gone!


thanks alot for the help!

also i'd like it if you explain a bit on what you wanted to learn from the link command so i can learn : )

now on to trying putting ogre in uiview... probably will need some help there to...
thanks
