QR Code Api/library

[areq47]

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?

[areq47]

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?

[wizard_hu_]

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]

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.
