我正在使用需要安装 libboost 的 ndnSIM 模拟器，当我尝试运行任何代码时，出现以下错误：
usr/local/lib/libns3-dev-emu-optimized.so: undefined reference to ns3::Queue::Dequeue()'
/usr/local/lib/libns3-dev-emu-optimized.so: undefined reference to ns3::CallbackBase::Demangle(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'

/usr/local/lib/libns3-dev-emu-optimized.so: undefined reference to typeinfo for ns3::Queue'
collect2: error: ld returned 1 exit status
我读到这可能是由于有两个 boost 库造成的。因此我运行了locate命令并得到了以下输出
locate libboost_system
/usr/lib/i386-linux-gnu/libboost_system.a
/usr/lib/i386-linux-gnu/libboost_system.so
/usr/lib/i386-linux-gnu/libboost_system.so.1.58.0
/usr/local/lib/libboost_system.a
/usr/local/lib/libboost_system.so
/usr/local/lib/libboost_system.so.1.62.0
这就是我收到错误的原因吗？如何在不影响我的模拟器的情况下升级或删除最旧版本？
