Question

所以，我正在尝试利用thrift，并决定生成一个C ++服务器。我正在使用CLion，clang和CMake来编译项目。但是，当我尝试编译生成的thrift服务器时，它会抱怨链接阶段缺少符号..

链接错误与我使用nm找到的这些符号有关：

0000000000000160 T __ZN6apache6thrift5async25TConcurrentClientSyncInfo10getPendingERNSt3__112basic_stringIcNS3_11char_traitsIcEENS3_9allocatorIcEEEERNS0_8protocol12TMessageTypeERi
0000000000000250 T __ZN6apache6thrift5async25TConcurrentClientSyncInfo13updatePendingERKNSt3__112basic_stringIcNS3_11char_traitsIcEENS3_9allocatorIcEEEENS0_8protocol12TMessageTypeEi

我的主要问题是我不知道如何继续。符号似乎在那里，导致错误的代码由thrift工具生成，而不是我。

以下是相关信息：

OS X 10.11.4
CMake 3.3
Apple LLVM version 7.3.0 (clang-703.0.29)

的CMakeLists.txt：

cmake_minimum_required(VERSION 3.3)
project(KodLogicDaemon)


include_directories(
    /usr/local/include
    ../Vendor/kod-logic
)

link_directories(
    /usr/local/Cellar/thrift/0.9.3/lib
)


set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -stdlib=libstdc++")

set(SOURCE_FILES

    main.cpp

    Thrift/DKLogic.cpp
    Thrift/interface_types.cpp
)

add_executable(KodLogicDaemon ${SOURCE_FILES})
target_link_libraries(KodLogicDaemon thrift KodLogic)

错误：

Undefined symbols for architecture x86_64:

链接libthrift时未定义的符号
