我在Windows 7 64位上使用MinGW。
我在NetBeans中使用了Google Test（按照Bo Qian的说明：http://www.youtube.com/watch?v=TS2CTf11k1U&feature=c4-overview-vl&list=PL5jc9xFGsL8GyES7nh-1yqljjdTvIFSsh&hd=1），它工作正常。最近我尝试将Google Mock（里面有Google Test）链接到我的项目。我使用了Cmake，这是我的CmakeLists.txt文件：

CMAKE_MINIMUM_REQUIRED(VERSION 2.8)
PROJECT(FS_Report)

INCLUDE_DIRECTORIES(${PROJECT_SOURCE_DIR})

SET(CMAKE_CXX_FLAGS_DEBUG "-g -Wall -std=c++11")

SET(GOOGLE_MOCK gmock-1.6.0)

ADD_SUBDIRECTORY(${GOOGLE_MOCK})

INCLUDE_DIRECTORIES(${PROJECT_SOURCE_DIR}/${GOOGLE_MOCK}/include)
INCLUDE_DIRECTORIES(${PROJECT_SOURCE_DIR}/${GOOGLE_MOCK}/gtest/include)

ADD_SUBDIRECTORY(source)

ENABLE_TESTING()

FILE(MAKE_DIRECTORY ${PROJECT_BINARY_DIR}/tests)

SET(TESTNAMES Aircraft Airport Exception FlightLevel
          FlightNumber PilotID Registration Remarks
          Route)

FOREACH(test ${TESTNAMES})
    ADD_EXECUTABLE(tests/${test}.test tests/${test}Test.cpp)
    TARGET_LINK_LIBRARIES(tests/${test}.test gmock_main)
    ADD_TEST(${test} tests/${test}.test)
ENDFOREACH(test)

CMake生成了Eclipse项目文件，它可以与MinGW一起使用。我在“source”文件夹中添加了一些测试和代码，然后我试图在Eclipse下构建它，但我得到了许多错误：

源文件中的类是正确的，因为我之前测试过它们。
我尝试添加一些标志到编译和重新安装MinGW，但它不工作。

当符号具有不正确的__declspec时，通常会发生这种情况（即，当绑定项目中的库源代码或链接到静态库时，您需要确保符号被修饰为__declspec(dllexport)）。
根据gmock自述文件：

To compile *gtest* as a shared library, add

  -DGTEST_CREATE_SHARED_LIBRARY=1

to the compiler flags. [...]

To compile your *tests* that use the gtest shared library, add

  -DGTEST_LINKED_AS_SHARED_LIBRARY=1

to the compiler flags.

因此，根据您是要针对gmock DLL还是要将gmock源代码编译到您的项目中，您需要定义相应的宏。

[...]

# elif GTEST_CREATE_SHARED_LIBRARY

# define GTEST_API_ __declspec(dllexport)

# endif

[...]
