Question

I have a OCR application. I’m using the tesseract api library for my app. But when i run the application, it will show the error (error: ISO C++ forbids declaration of ‘TessBaseAPI’ with no type?).

Here is myt.

@interface OCRViewController : UIViewController <UIImagePickerControllerDelegate,UINavigationControllerDelegate>{
   UIImagePickerController *imagePickerController;
   //Getting error in this line.
   TessBaseAPI *tess;
   UIImageView *iv;
   UILabel *label;
}

You’ll have to add the tesseract namespace, either with:

using namespace tesseract;

or:

tesseract::TessBaseAPI *tess;
