doubt
Although the system contains the C/C++ library that the so file depends on, the following problems still occur during the compilation process: undefined reference to `std::__cxx11::basic_string<char, std::char_traits<char>, std:: allocator<char> >::_M_replace_aux(unsigned long, unsigned long, unsigned long, char)'
solution
Upgrade the GCC compiler version of the system to 7, the original system version gcc version 4.8.2 (GCC)
