barcodescanner not working with phonegap.1.2.0

[fenta23]

Hello all,

i recently updated phonegap1.2.0 and migrated my project to the new
application. i imported the barcodescanner and got the following
error:

/<mypath>/PGBarcodeScanner.mm:21:26: error: PhoneGap/JSON.h: No such
file or directory

and

file://<mypath>/PGBarcodeScanner.mm: error: Lexical or Preprocessor
Issue: 'PhoneGap/JSON.h' file not found

any ideas?


thx in advance....
Micha.

[Giorgio Delle Grottaglie]

Replace 

#import <Phonegap/JSON.h>

with

#import <Phonegap/JSONKit.h>

[Michael P]

Gave it a try, but produce even more errors.

First error:
file://<mypath>/PGBarcodeScanner.mm: error: Semantic Issue:

counting mode
file://<mypath>/PGBarcodeScanner.mm: error: Automatic Reference

Is it because of armv7 architecture?

Try turning off auto reference count?

[Michael P]

Just read about Automatic Reference Counting. But where can i turn it off?
can't find it...

Thx.

+1 for another interested party. Definitely not an ObjectiveC guy and
struck this problem.

If you got it working Michael, would love to know how.

Thanks
Rowan

Interest me it... Can you solution it?

[Oliver86]

me too, getting errors because of the arc but can't find a way to
disable it.

I use Xcode 4.2, LLVM GCC 4.2...

I've opened up an issue for this:

here's a link to a stack overflow question on the topic:

[Michael P]

Thx Patrick,

i will try it...

but any solution for the barcodescanner problem yet?

Just about all caught up with stuff after my vacation, should be looking
into all the barcode scanner issues today.

I've opened a new bug to track the potential ARC issue. Looking for
work-arounds. My current thought is that if we can recognize ARC is
enabled for the compilation of the barcode files, that we cause the
compile to generate an error with a diagnostic message that "ARC is not
supported" (with more verbage, on how to recover, presumably).

Any thoughts welcome.

+1 here. Having the same issue.

Changing JSON.h to JSONKit.h worked for me.

As noted in https://github.com/phonegap/phonegap-plugins/issues/231 , it
turns out that you can just delete the JSON includes. The code used to
use the JSON libraries directly, but changed the code at some point so
that it's no longer needed.

[kelly]

I was able to fix this by using Giorgio's recommendation ("JSONKit.h"
replaces "JSON.h") followed by devgeeks recommendation (turning
automatic reference counting off).

However, to turn ARC off, I had to:

1) select the target in the project navigator
2) select the "build settings" tab
3) in the "build options" section, change the "Compiler for C/C++/
Objective-C" to "Apple LLVM compiler 3.0"
4) then in the "Apple LLVM compiler 3.0 - Language" section, change
the "Objective C Automatic Reference Counting" to "No"

I am running XCode 4.2 Build 4D199 on 10.7.2

I've added some proposed verbage to the Barcode Scanner readme
concerning disabling ARC, in the following issue:

[Patrick Mueller]

I have just pushed a number of changes to the phonegap-plugins
repository for the iOS BarcodeScanner. Here's a mini-changelog.
Hope this resolves the issues people have been hitting.

I should mention I tested with phonegap 1.2.0 on XCode 4.2 on Mac OSX
10.7. None of the changes I made should cause issues in other environments.

-------------------------------------------------------------
iOS BarcodeScanner: requires old JSON include in the .mm file
-------------------------------------------------------------

https://github.com/phonegap/phonegap-plugins/issues/231

Removed the JSON header files from the .mm file, as they were no longer
needed, and causing compile errors.

-------------------------------------------------------------
iOS BarcodeScanner: README fixes
-------------------------------------------------------------

https://github.com/phonegap/phonegap-plugins/issues/232

The README errors relating to the "barcodeScanner" typo have been
resolved. In addition, a note was added concerning the "build" process
only being needed if you update the zxing code.

-------------------------------------------------------------
iOS BarcodeScanner: does not compile / link when using ARC
-------------------------------------------------------------

https://github.com/phonegap/phonegap-plugins/issues/235

Added notes to the README on how to avoid compilation errors relating to
Automagic Reference Counting (ARC).
