Ios 框架示例项目（Mallmart）架构armv7的未定义符号：

我正在尝试从gimbal运行示例项目（Mallmart）

Mallmart已成功运行，但当我尝试使用IR运行Mallmart时，出现了此错误

Undefined symbols for architecture armv7:
  "QCAR::State::getNumActiveTrackables() const", referenced from:
      -[EAGLView renderFrameQCAR] in ContextIR
  "_OBJC_CLASS_$_CMMotionManager", referenced from:
      objc-class-ref in libQCAR.a(libQCAR.a-armv7-master.o)
  "QCAR::State::getActiveTrackable(int) const", referenced from:
      -[EAGLView renderFrameQCAR] in ContextIR
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我试图从vuforia-sdk-ios-2-0-29添加libQCAR.a，但仍然出现此错误

Undefined symbols for architecture armv7:
  "QCAR::State::getNumActiveTrackables() const", referenced from:
      -[EAGLView renderFrameQCAR] in ContextIR
  "_OBJC_CLASS_$_CMMotionManager", referenced from:
      objc-class-ref in libQCAR.a(libQCAR.a-armv7-master.o)

      -[EAGLView renderFrameQCAR] in ContextIR
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

有人能帮我解决这个问题吗

对不起，我的英语不好，我希望你明白我的意思

非常感谢您

关于您的项目目标构建设置您应该从有效架构中删除armv7s

很可能libQCAR.a不是为这种体系结构编译的。通过从您的项目中删除它，它将不再尝试在此体系结构中编译您的项目，这将解决您的问题

即使您没有为ARMV7编译，您的应用程序仍可以在较新的iOS设备上运行，但它不会对该体系结构进行所有优化
