给定这段代码，我得到:“对'QScriptEngine::QScriptEngine()的 undefined reference ”
#include <QtScript/QScriptEngine>
...
QScriptEngine e;
/* Commented out to understand the instantiation error first
e.globalObject().setProperty("t", 123);
bool result = e.evaluate("(t>=2 && t<5) || (t<1)").toBool();
*/
最佳答案
您是否在专业人士中声明了脚本？
QT += script
