Re: [osg-users] OSG 3.0.1 on iOS 5

[Büsra Gülten]

Hi Stephan,

thank you for your reply. 

After I compared my project with the iPhone-Example on github, I found out that 
the file PerlinNoise.cpp is missed in OpenSceneGraph-3.0.1-zip (which I 
downloaded from OSG-Website). This was the reason for the osgUtil-error 
mentioned above. 

Another point I want to indicate is when main-method look like this: 


 
 @autoreleasepool 
 {
 return UIApplicationMain(argc, argv, nil, 
 NSStringFromClass([osgAppDelegate class]));
 }
 


building of app is failed with this message: 


 ScopedLock: Parse Issue. Unknown type name 'namespace'. 
 Parse Issue. Expected '.' after top level declarator
 
 Notify: Lexical or Preprocessor Issue. 'ostream' file not found. 


Any idea what this could be mean?

Thank you!

Cheers,
Büsra

Looks like your main-file gets compiled as Objective C only and chokes
about some c++-stuff. Try renaming the file from *.m to *.mm

 I have already build OSG 3.0.1 on iOS 4. Now i would like to build it on iOS

Please check if you added libosgUtil to your linking stage of your app.


 I have also tried the newest iPhone Example on github. I get there similar 
 error I mentioned above:
 
 

 ld: warning: ignoring file 
 /../IPhone_Project/3rdParty/lib/libFreeType_iphone_universal.a, missing 
 required architecture i386 in file

Unfortunately the packaged freetype lib for iphone is for device only
(arm6/7), not for the simulator (i386). This exlains your errrors about
missing symbols. But you can build libfreetype by yourself...

I did a quick test with the examples from the github-repository and they
do compile und run fine for IOS 5.


cheers,

Stephan
