I tried to include a library for converting xml to json in my qt project (in the Cheedoong/xml2json github). Got error error: 4 duplicate symbols for architecture x86_64. There is no error in xcode. Tell me how to fix it for qt

It's not a library, it's a piece of shit code. And you probably added #include <xml2json.hpp>to filefactory.cpp and xmlfile.cpp? Well, it's not meant to be used. Include it in one cpp, and copy function prototypes into a separate header and include it in all other cpps where these functions are needed.
