Problems Integrating a project using Linea barcode scanner libraries

[Mike Silvers]

I am using iOS 5, xcode 4.3.3.  I have followed the great directions for integrating this project into my current project.  The directions I am using are these: https://github.com/RestKit/RestKit/wiki/Installing-RestKit-in-Xcode-4.x  

In my project, I am using the library libdtdev.a provided by LineaPro for their barcode and card reader attachment for the iPhone and iPod touch.  It looks like there is a conflict with the audio files required for the libdtdev.a and the RestKit classes.  When I remove RestKit the build ends successfully.  

Any ideas?

After following the installation directions, I attempted a build and received the following errors:

Did you ever figure out how to resolve this issue Mike?

[RBarnes]

Not sure if anyone will see this or care but just in case someone stumbles across this article from a search (like I did), here's the solution I found:

I encountered the same issue working with XC 6.1, targeting iOS 7.1, using Infinite Peripherals SDK 1.93.  I had to add Frameworks AudioToolbox, MediaPlayer, and AVFoundation.  Tech at IP indicated that they were working on adding bluetooth audio and thought this might be why these were required.

The really screwy thing is that using SDK 1.89, I did not encounter these link errors, only with SDK 1.93.  But, even more screwy:  With one project, I didn't need to include them for EITHER SDK.  But with another project, I did.  And the ONLY difference was the inclusion of the new SDK.  Both projects built with SDK 1.89 without errors.  One project would build with 1.93 without errors.  The other project required adding these frameworks.  I don't get it.  But adding them solved the issue.

Thanks, Rod. That's very helpful. I will be putting together a new application soon using the same set of tools and this will likely prove invaluable.

Best Regards,

Jeff Lee

Just wanted to post to say thank you ! I have been tearing my hair out for the past 2 hours trying to figure out why it would not compile when both the Linea Pro SDK and the RestKit were used.

Thank you !


Chris.
