Question

我在Windows 7 64bit上使用MinGW。

我使用了NetBeans的Google Test（遵循Bo Qian指令：http://www.youtube.com/watch?v=TS2CTf11k1U&feature=c4-overview-vl&list=PL5jc9xFGsL8GyES7nh-1yqljjdTvIFSsh&hd=1）并且它正常工作。最近我尝试将Google Mock（内置Google Test）与我的项目联系起来。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生成的Eclipse项目文件，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，然后我尝试在Eclipse下构建它，但是我遇到了很多错误：

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来编译并重新安装MinGW，但它不起作用。

这通常发生在符号不正确__declspec时（即在项目中捆绑库源或链接到静态库时，需要确保符号被装饰为__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，根据您是否喜欢gmock DLL或将gmock源代码编译到项目中，您需要定义相应的宏。看起来您没有链接DLL，因此您可能需要-DGTEST_CREATE_SHARED_LIBRARY=1，因为在gtest-port.h中您会找到

[...]
# elif GTEST_CREATE_SHARED_LIBRARY
#  define GTEST_API_ __declspec(dllexport)
# endif
[...]

使用MinGW的Bad Reloc地址
