What steps will reproduce the problem?
1. Include the binary library and header files
2. Try and build the project.

What is the expected output? What do you see instead?
Expected build successful.

Actual output:

Undefined symbols:
  "_gLogging", referenced from:
      _gLogging$non_lazy_ptr in libiphone-exif.a(EXFJpeg.o)
      _gLogging$non_lazy_ptr in libiphone-exif.a(EXFJFIF.o)
      _gLogging$non_lazy_ptr in libiphone-exif.a(EXFMetaData.o)

Build failed (1 error)


Workaround: include 

BOOL gLogging = FALSE;

variable definition in AppDelegate .m file.

error:type of accessor does not match the type of property 'definitions'

What steps will reproduce the problem?
1. Running on OS 2.0 will produce error

Dear Mr. Woodcock,

I am interested in licensing this code for a project I am working on, can
you contact me at http://www.sevenshadow.com/contact?

Thank you,

Charlie

What steps will reproduce the problem?
1. Read and populate metadata from jpg file (iOS SDK 4.3)
EXFJpeg* jpegScanner = [[EXFJpeg alloc] init];
[jpegScanner scanImageData: jpegData];
EXFMetaData* exifMetaData = jpegScanner.exifMetaData;
NSMutableData* newJpegData = [[NSMutableData alloc] init];
[jpegScanner populateImageData:newJpegData :exifMetaData];


What is the expected output? What do you see instead?
This shound not change any EXIF/JFIF etc value.
How ever it seems it breaks some values in metadata.
Wrong  values are in the following tags:
ApertureValue, FNumber, FocalLength, ShutterSpeedValue

Correct values are in:
ColorSpace, Exif version, Pixel X/Y dimension and few more

Missing values:
ExposureProgra, ISO, SUbkect Are

I also noticed that some values are moved to other tags:
FocalLength moved to FNumber
ApertureValue moved to ExposureTime





What version of the product are you using? On what operating system?
0.9

I am getting a warning in the file EXFMetaData.m

In the routine appendDataFromBytes, it uses logical AND (&&) and I wondering if 
the author meant to use bitwise AND (&).

It is completely possible the code is correct but I just do not know enough 
about the code to know if the warning I am getting is bogus.

Thank you.

What steps will reproduce the problem?
1. svn checkout of the source
2. copy all *.h and *.m into your personal project

_gLogging can't be found.

just managed the definition in EXFLogging.h
from:
#define Debug(FMT,...)  if(!gLogging) ; else  NSLog(@"DEBUG: " FMT, 
##__VA_ARGS__)

to:
#define Debug(FMT,...)  if(1 == 2) ; else  NSLog(@"DEBUG: " FMT, ##__VA_ARGS__)

not so elegant as solution, but it works for tests.

What steps will reproduce the problem?
1. build for distribution (adHoc), install on device via iTunes
2. "run"
3.

What is the expected output? What do you see instead?
Works fine when built for debug, or built for distribution on the simulator but 
crashes to the 
springboard when built for adHoc on device

What version of the product are you using? On what operating system?
latest (0.9)

Please provide any additional information below.

The offending method is scanImageData, and within that commenting out 
parseExif: will cure 
the crash (but not return any data!) Typical crash log is below, this is a jpg 
imaged loaded into 
NSData and passed to scanImageData as follows:

NSData *uiJpeg =  [NSData dataWithContentsOfFile:[[NSBundle mainBundle] 
pathForResource:self.imageFilename ofType:@"jpg"]]; 
    if ([uiJpeg length] != 0) {
        [jpegScanner scanImageData:uiJpeg];

What steps will reproduce the problem?
1. I add framework and *.h from Release-simulator-iphonesimulator 
2. then I only want to test the simply demo, codes are:

exifTestViewController.h

#import <UIKit/UIKit.h>
#import "EXF.h"
@interface exifTestViewController : UIViewController {
    //lsy 110929 00:00am
    UIImage *exifImg_lsy;
    UIImageView *imgDisplayImgView_lsy;
    NSData *imageData_lsy;
}

@property (nonatomic,retain) UIImage *exifImg_lsy;
@property (nonatomic,retain) IBOutlet UIImageView *imgDisplayImgView_lsy;
@property (nonatomic ,retain ) NSData *imageData_lsy;


@end


exifTestViewController.m

#import "exifTestViewController.h"

@implementation exifTestViewController
//lsy 110929 00:00am
@synthesize exifImg_lsy;
@synthesize imgDisplayImgView_lsy;
@synthesize imageData_lsy;
- (void)viewDidLoad {

    //lsy 110929 00:00am
    exifImg_lsy = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"test" ofType:@"jpg"]];
    [imgDisplayImgView_lsy setImage:exifImg_lsy];
    NSData * uiJpeg = UIImageJPEGRepresentation (exifImg_lsy, 1.0 );
    EXFJpeg* jpegScanner = [[EXFJpeg alloc] init];
    [jpegScanner scanImageData: uiJpeg];
    //self.imageData_lsy = jpegScanner;
    NSLog(@"picture length:::%d",jpegScanner.exifMetaData.height);  
    [jpegScanner release];
    [super viewDidLoad];
}
3.then error disappeared:

What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?
iphone simulator 4.2

Please provide any additional information below.

What steps will reproduce the problem?
1. build in Xcode 3


What is the expected output? What do you see instead?
Expected output is success

Build reports 1 error:
EXFGPS.h:0: No header or class discussion/abstract found. Creating dummy file 
for default 
content page.

The library builds correctly just the docs are not quite right

Please use labels and text to provide additional information.

So im trying to add the libiphone-exif.a library to my project on xcode 4.0.2 
but im having trouble adding this correctly. Whenever i try adding it as a 
framework, it is being added as a textfile and does not recieve the toolbox 
icon that frameworks get. Probably an amateur question but i would greatly 
appreciate the help. thanks

i using Exif library for my application so this type error accoure

Please help me.

What steps will reproduce the problem?
1. set release or distribution build at level o2|o3
2. build onto device
3. repeated access to API results in EXEC_BAD_ACCESS

What is the expected output? 
Expected is correct behaviour


Debug setting on any optimisation level does not produce this behaviour. 
Setting optimisation 
level to o1 does not produce this behaviour.

This library is currently using the GPLv2 License. 

This means any use of this library would require the using program to be also 
licensed as GPLv2 as I understand it.

However, due to the restrictions of the Apple App Store (distribution and the 
like) the license is incompatible with the Terms and Conditions signed upon the 
uploading of any Apps. 

http://www.fsf.org/news/2010-05-app-store-compliance 
The above blog post talks of GNU Go on the App Store (it was eventually removed 
from the App Store as Apple will not change their Terms and Conditions). 

With all due respect to your kind efforts, could you please release this 
library under a different license (LGPL perhaps) that would allow other non-GPL 
programs to use your library without modification.

Kind Regards
Daryl
