Hi, everyone,
i tried to add osg libraries to my iphone project. I compiled the libraries
from git's iphone example. But, after i added them to my project
(libOpenThreads.a, libosg.a, libosgDB.a, blah blah...), i can not compile my
project sucessfully.
i just made a declaration in the header, so please watch my code:
CameraAVController.h:
Code:
#include "osgPlugins.h"
#include <osgDB/ReadFile>
#include <osg/MatrixTransform>
#include <osgViewer/Viewer>
#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>
#import <CoreGraphics/CoreGraphics.h>
#import <CoreVideo/CoreVideo.h>
#import <CoreMedia/CoreMedia.h>
@interface CameraAVController : UIViewController
<AVCaptureVideoDataOutputSampleBufferDelegate> {
... ...
osg::ref_ptr<osgViewer::Viewer> _viewer;
}
......
@end
CameraAVController.mm:
Code:
#import "CameraAVController.h"
#include <osgGA/TrackballManipulator>
#include <osgGA/MultiTouchTrackballManipulator>
#include <osg/ShapeDrawable>
#include <osg/DisplaySettings>
These are some of the thousands of error informations below:
