std::basic_string满足知分配器容器(AllocatorAwareContainer)(但不使用定制的construct/destroy构造/析构元素)、序列容器(SequenceContainer)及连续容器(ContiguousContainer)(C++17 起)。 如果Traits::char_type或者Allocator::char_type与CharT不同,那么程序非良构。
TensorRT_SDK::init(std::basic_string<char, std::char_traits<char>, std::allocator<char> >, int) 3.与报错信息对比后发现是std::__cxx11::basic_string与std::basic_string没有匹配上 GCC 5在编译时会将std::string类型按c++11下std::__cxx11::basic_string<char> 来处理,这时如果你调用的库在...
