Description

The customer has an issue regarding to add third-Party iOS Framework which causes build error. The module is packaged successfully on SDK 7.5.1.GA. *Sample Test module*: https://www.dropbox.com/s/fz79its9l8w1kt6/iosTestModule1.zip?dl=0 *Steps to reproduce:* 1. Download and unzip the attached iosTestModule file. 2. Open titanium.xcconfig file,update Titanium SDK path in titanium.xcconfig file.


TITANIUM_SDK_VERSION = 7.5.1.GA

//
// THESE SHOULD BE OK GENERALLY AS-IS
//
TITANIUM_SDK = /............./Library/Application Support/Titanium/mobilesdk/osx/7.5.1.GA
TITANIUM_BASE_SDK = "$(TITANIUM_SDK)/iphone/include"
TITANIUM_BASE_SDK2 = "$(TITANIUM_SDK)/iphone/include/TiCore"
TITANIUM_BASE_SDK3 = "$(TITANIUM_SDK)/iphone/include/JavaScriptCore"
HEADER_SEARCH_PATHS= $(TITANIUM_BASE_SDK) $(TITANIUM_BASE_SDK2) $(TITANIUM_BASE_SDK3)

3. Now package the module and bind to a sample Appc project. 4. Try to run the sample project and observe the error.

[ERROR] :  ** BUILD FAILED **
[ERROR] :  The following build commands failed:

[~fhaque] 1. I am not able to get module from shared link. Please share the module again. 2. Is error happening for running the module for device and simulator both?

We have some update from the customer about their module. They are planning to integrate Kofax iOS mobile SDK with our Appcelerator mobile app. Kofax offers data capture module for mobile apps to capture images, process and extract data correctly (from physical documents/papers) with device camera. To call kofax native iOS APIs from JavaScript, they are creating a custom module for iOS (integrating Kofax Mobile SDK). Please find below some useful links. https://www.kofax.com/Products/Mobile-Capture/Mobile-SDK/Features https://knowledge.kofax.com/Mobile_Capture https://www.kofax.com/-/media/Files/Datasheets/EN/ps_kofax-mobile-sdk_en.pdf

Probably linking thee AudioToolbox framework correctly will fix this. This is no Titanium bug.

[~vijaysingh],Here is the response from the customer:

   
   This Kofax framework needs other Apple frameworks/libraries to be added in the module. So we have added them to the module and the framework names are updated in the module.xcconfig file. 
   Below are the list of dependencies for kofax: 
   1. Accelerate.framework 
   2. MobileCoreServices.framework 
   3. CoreMotion.framework 
   4. AssetsLibrary.framework 
   5. AudioToolbox.framework 
   6. SystemConfiguration.framework 
   7. CoreMedia.framework 
   8. CoreLocation.framework 
   9. Foundation.framework 
   10. libz.tbd 
   11. libxml2.tbd 
   12. libsqlite3.tbd 
   13. libc++.tbd 
   
   After packaging the module with the above changes and target to a sample app. When running the sample app still produces an error. Attached the sample module in below dropboxlink. 
   
   URL: https://www.dropbox.com/sh/nab40u3sb7as9rw/AAALdv16SxrC9qMPQpLjrdpka?dl=0 
   
   After adding all the above frameworks, we are unable to see the mentioned error “_vDSP_dotprD” in the build log file. Attached is the sample app’s build log file.
