# Undefined reference wheh using QScriptEngine and QScriptValues.

• Hello, I need to parse jsons array that I receive through a Network request.

I saw this website: http://qtwiki.org/Parsing_JSON_with_QT_using_standard_QT_library
and tried simulate that technique. The problem is that, when I instantiate QScriptEngine and QScriptValue
type objects, I get the following build errors:

undefined reference to `_imp__ZN12QScriptValueC1Ev' undefined reference to`_imp___ZN13QScriptEngineC1Ev'
undefined reference to `_imp___ZN13QScriptEngine8evaluateERK7QStringS2_i' undefined reference to`_imp___ZN12QScriptValueD1Ev'
undefined reference to `_imp___ZN13QScriptEngineD1Ev' undefined reference to`_imp___ZN13QScriptEngineD1Ev'
undefined reference to `_imp___ZN12QScriptValueD1Ev' undefined reference to`_imp___ZN12QScriptValueD1Ev'

Maybe there's something missing from my Qt installation?
Any help would be very appreciated.

Thanks,

Sergio

• You need the Qt Script module. Add to your .pro file:

@
QT += script
