节俭生成的代码未定义的参考

Thrift generated code undefined reference

本文关键字：代码 参考 未定义      更新时间：2023-10-16

我正在尝试编写一些代码来使用节俭生成的代码，但我要获得的只是生成代码的错误。我使用的是Thrift 0.10.0和G 5.4.1。

错误： 

server/libserver.a(TalkService.cpp.o): In function `std::less<lineserver::Contact>::operator()(lineserver::Contact const&, lineserver::Contact const&) const':
TalkService.cpp:(.text._ZNKSt4lessIN10lineserver7ContactEEclERKS1_S4_[_ZNKSt4lessIN10lineserver7ContactEEclERKS1_S4_]+0x23): undefined reference to `lineserver::Contact::operator<(lineserver::Contact const&) const'

用于生成的旧约文件： line.thrift

我真的很喜欢这个帮助，因为我已经试图找出解决方案了一段时间。

可能是您周围/传输创建周围有一些混乱（看来您正在使用Transport类型创建套接字）。

您应该尝试在客户端创建以下内容的通信堆栈：

boost::shared_ptr<TSocket> socket(new TSocket("host", "port"));
boost::shared_ptr<TTransport> transport = boost::shared_ptr<TTransport>(new THttpClient("https://gd2.line.naver.jp", 443, "/api/v3/TalkService.do"));
boost::shared_ptr<TProtocol> protocol(new TBinaryProtocol(transport));
TalkServiceClient client(protocol);

设置"主机"answers"端口"值，在您的情况下需要。遵循此创建模式，我成功使用了节俭。
