I try to build my app, with xzingwidget, on xcode 5.1 and I get the following error.

'CHECKSUM_EXCEPTION_H' is used a header guard here, followed by #define of a different macro

I have to change some build setting?

SOLUTION

This Xcode 5.1 unused consts treated as error helped me to find the solution.

I removed all "Apple LLVM 5.1 Custom Compiler Flags" in the ZXingWidget target, now everything works

  • What is xzingwidget? Is that the only error? Did you follow some sort of tutorials for this? – Enrico Susatyo Mar 13 '14 at 10:58
  • I use this: http://basheerad.blogspot.it/2012/04/integrating-zxing-qr-code-reader-in.html and this: http://stackoverflow.com/questions/12968369/undefined-symbols-for-architecture-armv7-when-using-zxing-library-in-xcode-4-5 With xcode 5.0.2 I can build my app, but with the new xcode 5.1 I get the error during the building phase – Batti Mar 13 '14 at 11:25
  • I really need more info. That can't be the only error message. – Enrico Susatyo Mar 13 '14 at 11:35

On deployment target iOS7 there seems to be the need to set the compilers to C++ 11 (sdt) as well as libc++ (LLVM)

After switching those settings the build runs successfully

You can refer to here for more info.

There is a typo in the lib. It should be :

#ifndef __CHECKSUM_EXCEPTION_H__
#define __CHECKSUM_EXCEPTION_H__
....

instead of :

#ifndef __CHECKSUM_EXCEPTION_H__
#define __NOT_FOUND_EXCEPTION_H__
....
