I'm trying to write some code to work with Thrift-generated code but all I'm getting is a error on generated code. I'm using Thrift 0.10.0 and g++ 5.4.1.

Error:

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'

    return 0;

file(GLOB SRC_FILES line_constants.cpp line_types.cpp TalkService.cpp)
add_library(server ${SRC_FILES})

target_link_libraries(server ${THRIFT})

Thrift file used for generating: line.thrift

I'd really love some help with this because I've been trying to figure out the solution for quite some time.

May be you have some confusion around socket/transport creation (it seems you're creating a socket with the TTransport type).

You should try to create the communication stack as follows on the client side :

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);

Set "host" and "port" values as needed in your case. Following this creation pattern I successfully used thrift.

  • I made the changes but I don't think the error is being caused by main.cpp because it is still the same even after making the changes – highafdoge Sep 08 '17 at 17:33
  • Could you provide the thrift generated output files ? It seems your Contact class/struct is missing the operator< definition, needed by (maybe) an STL container. – Theforgotten Sep 11 '17 at 06:36
