Question

我正在尝试编译QT Bitcoin Trader，但由于某些原因，在配置openssl后，我的方法出错了。

qtBitcoinTrader.cpp

void QtBitcoinTrader::sayText(QString text)
{
    Q_UNUSED(text)
#ifdef Q_OS_MAC
    static SpeechChannel voiceChannel;
    static bool once=true;
    if(once)
    {
        once=false;
        NewSpeechChannel((VoiceSpec*)NULL, &voiceChannel);
    }
    CFStringRef talkText=CFStringCreateWithCharacters(0,reinterpret_cast<const UniChar *>(text.unicode()), text.length());
    SpeakCFString(voiceChannel, talkText, NULL);
    CFRelease(talkText);
#else
#ifdef Q_OS_WIN
#ifdef SAPI_ENABLED
    static ISpVoice *pVoice=NULL;
    static HRESULT hr=CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, (void **)&pVoice);
    if(SUCCEEDED(hr))
    {
        pVoice->Speak(NULL,SPF_PURGEBEFORESPEAK,0);
        pVoice->Speak((LPCWSTR)text.utf16(), SPF_ASYNC, NULL);
    }
#endif
#else
    startApplication("say",QStringList()<<text);
#endif
#endif
}

是否存在验证我是否错误引用库的方法？

您尚未在构建中添加ApplicationServices和CoreFoundation框架，并且您也错过了系统libz。将以下内容添加到.pro文件中，然后重新运行qmake并再次构建：

LIBS += -framework ApplicationServices -framework CoreFoundation -lz

QtBitcoinTrader找不到sayText方法
