Hi, I am experimenting a few things with the OCR demo application. It is crashing in "ocrimage" function on calling "tess->tesseractRect" after I select any image from image picker. This is happening every time. I am trying to debug the issue, but posting here also, just in case you have any idea about this. I am using iphone simulator 3.1, sdk and xcode version 3.1.4

Thanks,
Vikram

I'm trying to compile your demo using the oldest iOS sdk available nowadays which is 3.2
At runtime, after taking the photograph the program crashes with EXC_BAD_ACCESS during the following call:
char* text = tess->TesseractRect(imageData,(int)bytes_per_pixel,(int)bytes_per_line, 0, 0,(int) imageSize.height,(int) imageSize.width);

Other users are experiencing the same problem, there's a stackoverflow thread about it:
http://stackoverflow.com/questions/4560587/business-card-reader-or-ocr-library-for-iphone-sdk

Have you tried running your code with SDK 3.0 or greater?
Thanks for your precious work!

I cloned the source today and built the iphone OCR demo for 4.3

The application starts ok (Simulator), and on clicking the 'show image picker' button the UIImagePicker appears allowing me to select an image. Selecting the image shows a 'OCRDEMO - working' Alert for 1-2 seconds, then the app crashes with debugger output of this:

Detected an attempt to call a symbol in system libraries that is not present on the iPhone: clock$UNIX2003 called from function _Z17edges_and_textordPKcP10BLOCK_LIST in image OCRDemo. If you are encountering this problem running a simulator binary within gdb, make sure you 'set start-with-shell off' first.

It doesn't help that I don't exactly know how to 'set start-with-shell off'

My fear is that this is an issue caused by 4.3 since a search for the key components of the error come up short.

Getting the following error when trying to run on Simulator, runs fine of Device:

Detected an attempt to call a symbol in system libraries that is not present on the iPhone:
fputs$UNIX2003 called from function _Z7tprintfPKcz in image OCRDemo.
If you are encountering this problem running a simulator binary within gdb, make sure you 'set start-with-shell off' first.

Any ideas?

Thanks

Hi ,

I am new at iOS. I have a project like you have done. I have tried to develop my own using yours but it is showing errors. Please help me to resolve this.

Thanks,
Cp

I modified the code, compiled and run the code which does all the above fine, when but I try to archive it, Im getting an error

error: strip /Users/mac1/xfer/Ananth/Projects/OCRSample/Resources/nolanbrown-Tesseract-iPhone-Demo-6338e61/OCRDemo/Classes/tesseract-3.01/vs2008/lib/liblept.lib: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/strip received signal 11

I didn't ever faced this error before and so I surfed but didn't find any relative solutions to it. Im using xcode version 4.3.2 and Mac OS, version 10.7.4

NSInternalInconsistencyException', reason: 'Application windows are expected to have a root view controller at the end of application launch

i'm getting a error "clang: error: unknown argument: '-stdc++'" if tried to run in xcode6.1

Hello!

When I try to run my app on iPad, it crashes at launch.

This is the log:

Unable to load unicharset file /var/mobile/Applications/2BF9E121-322D-4A6A-9646-1905F49DBD44/Documents/tessdata/eng.unicharset

How can I resolve it?
