Linker errors in XCode when PDFTron is added

Technical Support Apryse SDK

Hi,

I am using XCode 4.2 and iOS SDK version 4.2. I am getting a linker
error even after following the steps as mentioned in the Readme
included in the zip download.
Undefined symbols:
  "_OBJC_CLASS_$_PDFDoc", referenced from:
      objc-class-ref-to-PDFDoc in PdfOpsViewController.o
  "_OBJC_CLASS_$_PDFViewCtrl", referenced from:
      objc-class-ref-to-PDFViewCtrl in PdfOpsViewController.o
  "_OBJC_CLASS_$_PDFNet", referenced from:
      objc-class-ref-to-PDFNet in PdfOpsViewController.o

Please help.

Regards,
Sayali

Hello Sayali,

Is the sample app compiling correctly for you? If so, there must be a difference between the sample project and your project. Are you perhaps looking at an old read me, and not including PDFNetOBJC.h? Are you including Private.h? Are you including the library libPDFNet.a?

Please let me know if you are able to get it to compile, or if the problem persists.

Best regards,
James
