QR Code Api/library

**areq47** · 2012-12-11, 09:12

Hello,

I am looking for Api or library (OpenSource or licensing) which allow me to read QR code. I found only ZXing, but it use Open-C++ so it does not support old Symbian OS. I will be gratefull for any suggestions.

It certainly takes some time, but it should be possible to replace standard C/C++ stuff with Symbian C++. In case of a barcode reader I would not expect heavy-weight library (STL, etc.) dependence anywhere, it is mostly mathematics.

I am interested in completed solutions rather than implement this algorithm.

Probably there aren't any then. Open C has been around for a while - just how "old" do you want to go?

My application must work on Symbian S60 3rd and newer.

What is wrong with Open C/C++ then? It is available for S60 3rd edition and newer. See the plug-ins table on https://www.developer.nokia.com/Deve...ian_C++/Tools/

When I want to build my applicaton on old devices such as Nokia N82 I have to add the following lines to build my application properly:

@"$(EPOCROOT)Epoc32\..\nokia_plugin\openc\s60opencsis\pips_s60_1_6_SS.sis", (0x20013851)
@"$(EPOCROOT)Epoc32\..\nokia_plugin\openc\s60opencsis\openc_ssl_s60_1_6_SS.sis",(0x200110CB)
@"$(EPOCROOT)Epoc32\..\nokia_plugin\openc\s60opencsis\openc_glib_s60_1_6_SS.sis",(0x200110CC)
@"$(EPOCROOT)Epoc32\..\nokia_plugin\opencpp\s60opencppsis\STDCPP_s60_1_6_SS.sis",(0x2000F866)

But then, during installation on newer devices (Symbian S60 5th Edition and newer) I receive the message: "Update error". My client want to have just one application, so I have to always add this lines to the pkg files.

Unless you know a solution how to prevent this error?

1.6 is a bit ancient, consider getting the latest version. Which is 1.7.5 for a long time by now. That may already solve the error.

**areq47** · 2012-12-13, 09:12

I installed 1.7.5, but problem still occured. When I don't include this 4 files to the .pkg everything is OK.

You could try adding them one by one, at least that would reveal which is the problematic one. For example a QR-code API probably does not use SSL and GLIB, and in fact there are good chances that it does not use STDCPP either.

You may want to consider searching for the mentioned library (ZXing) using Google.
