Hi All,

I have problem when using ZXing, but i believe that this error is not because ZXing libraries. I have This error
"\zxing\multiformatreader.cpp:41: error: undefined reference to `__cxa_get_exception_ptr'"

when Try to build QQRDecoder application in this "link":http://www.developer.nokia.com/Community/Wiki/Qr_Decoder_in_Qt so after that i try to create my own application. And i found that same error again.

any body can help me???

Thanks in advance

Seems you didn't link the library. Try clean & qmke & make again if you sure you linked the lib

I thing that 4.7.4 is Qt's version for the "custom" edition used by Qt Creator. The actual library you link your application against is 4.7.3.
