Linker Can'；t链接。实际存在和定义的未定义符号

我有一个成功为Windows、Linux构建的跨平台解决方案，但在Mac OS X构建期间，我遇到了这样的问题：

   Undefined symbols for architecture x86_64:
      "qx::syb::DataType<boost::shared_ptr<qx::DistributedObject>, void>::DataType()", referenced from:
          qx::syb::AbsDynInfo const& qx::syb::dynInfo<boost::shared_ptr<qx::DistributedObject> >()in ThemeKit.cpp.o

    ld: symbol(s) not found for architecture x86_64

这个问题与编译器优化有关。像-O1这样的使用受限优化是可能的，但更高级的-O2或-O3会产生这样的错误

bash-3.2$ nm -arch x86_64 -U instance*.o | c++filt | grep -i "qx::syb::DataType<boost::shared_ptr<qx::DistributedObject>, void>::DataType()"
00000000001e6e68 S qx::syb::DataType<boost::shared_ptr<qx::DistributedObject>, void>::DataType()
