Question

编译thrift 0.9.1 cpp代码时遇到问题。

我的makefile是这样的：

objects = genFeaVec_multiThread_HSV.o imgIDservice_types.o ImgIDdifNameService.o

genFeaVec_multiThread_HSV_thrift : $(objects)


g++ -o genFeaVec_multiThread_HSV_thrift $(objects) -I/usr/include -L/usr/lib64 -lopencv_calib3d -lopencv_features2d -lopencv_highgui -lopencv_video -lopencv_imgproc -lopencv_core -lthrift

编译器g ++告诉：

g++ -o genFeaVec_multiThread_HSV_thrift genFeaVec_multiThread_HSV.o imgIDservice_types.o ImgIDdifNameService.o -I/usr/include -L/usr/lib64 -lopencv_calib3d -lopencv_features2d -lopencv_highgui -lopencv_video -lopencv_imgproc -lopencv_core -I/usr/include/ -L/usr/lib64 -lthrift -lthriftnb -levent
undefined reference to `apache::thrift::transport::TSocket::TSocket(std::string const&, int)'

我的cpp代码是这样的：

std::string host_i=string("localhost");
boost::shared_ptr<TTransport> socket(new TSocket(host_i,9537));

我尝试过host_i.c_str（）和＆＃34; localhost＆＃34;但它不起作用。我检查了lib -lthrift：

nm -CD /usr/lib64/libthrift-0.9.1.so | grep TSocket

`00000000000670f0 T apache::thrift::transport::TSocket::TSocket(int)
0000000000066ea0 T apache::thrift::transport::TSocket::TSocket(std::string)
0000000000066d80 T apache::thrift::transport::TSocket::TSocket(std::string, int)
0000000000066fc0 T apache::thrift::transport::TSocket::TSocket()
00000000000670f0 T apache::thrift::transport::TSocket::TSocket(int)
0000000000066ea0 T apache::thrift::transport::TSocket::TSocket(std::string)
0000000000066d80 T apache::thrift::transport::TSocket::TSocket(std::string, int)`

包含文件没问题。在目的地/usr/include

我认为问题仍然是如何导入lib。但我不知道我的makefile有什么问题。

Answer 1

尝试使用其他库：stdlib libc++，而不是libstdc++和-lthrift。

Cpp未定义引用`Apache :: thrift :: transport :: TSocket :: TSocket（std :: string const＆amp;，int）＆＃39;
