Question

我正在处理一个应用源代码，该代码由于某种原因禁用了In App Purchase代码（已注释掉）。该游戏是在Cocos 2dx中构建的。

现在，我对C ++一无所知，但我研究过试图找到答案并且我被卡住了。

我得到了编译错误：

Undefined symbols for architecture arm64:

  ShopLayer::onClickPopBuy() in ShopLayer.o
  MainMenuLayer::init() in MainMenuLayer.o
  MainMenuLayer::onLeaderBoard(cocos2d::CCObject*) in MainMenuLayer.o

以下是整个代码块：

void ShopLayer::onClickPopBuy()  {

   if (g_nProgressBuy != -1) {
     itemPopBuy->setEnabled(false);
     AndroidSocial::shared()->buyFeatureB(m_curPopIdx);
     g_nProgressBuy = -1;
     this->schedule(schedule_selector(ShopLayer::onProcessBuy), 0.5f);
   }

   if ( spPop1->isVisible() ) {
    // Compiler Error: use of undeclared identifier 'BLACKJACK'
    BLACKJACK::BlackJackSetting* bj = BLACKJACK::BlackJackSetting::shared();
      if ( bj->isPaidVersion() ) {
        bj->processIAP("com.prismstudios.BlackjackPaid.coin1000");
      }
      else
      {
        bj->processIAP("com.prismstudios.Blackjackfree.coin1000");
      }

      GameSetting* gameSetting = GameSetting::shared();
      gameSetting->getCoins();

      if ( bj->isCoins1000() ) {
        g_nYourCoin += 1000;
      }

      gameSetting->saveCoins();
     }
   }

更新 - BlackJackSetting.m文件：

  NSLog(@"enable GC %d", enable);

  BLACKJACK::BlackJackSetting *gc = BLACKJACK::BlackJackSetting::shared();
  gc->isEnabled = enable;

看起来这个代码是从其他项目导入的。 BLACKJACK是一个名称空间，用于定义引用的范围。你需要一个BlackJackSetting类（即它的所有代码）。您可能根本不需要命名空间（BLACKJACK）。
