在CMake中OpenCV和Gtest冲突

Question

我正试图在我的应用程序上做一些谷歌测试，我遇到了OpenCV和GTest之间的一些冲突:

/usr/lib/gcc/i686-linux-gnu/4.6/../../../../lib/libgtest.a(gtest-all.cc.o): In function `testing::internal::GTestLog::GTestLog(testing::internal::GTestLogSeverity, char const*, int)':
gtest-all.cc:(.text+0xdd84): multiple definition of `testing::internal::GTestLog::GTestLog(testing::internal::GTestLogSeverity, char const*, int)'
/usr/local/lib/libopencv_ts.a(ts_gtest.cpp.o):ts_gtest.cpp:(.text._ZN7testing8internal8GTestLogC2ENS0_16GTestLogSeverityEPKci+0x0): first defined here 
...

GTest在opencv_ts库中使用。有人知道如何解决这些多重定义吗?

我认为，如果我只添加我从OpenCV使用的库，它将被解决，但我不知道如何做到这一点。我试过了:

target_link_libraries(${Exec8name}_test ${OpenCV}/opencv_core.so* ... )
target_link_libraries(${Exec8name}_test ${OpenCV_LIBS}/opencv_core.so* ... )
target_link_libraries(${Exec8name}_test ${OpenCV_LIBS_DIR}/opencv_core.so* ... )

等，但我得到的只是错误没有找到或No rule to make tarket

我试图删除其中一个，但我得到

的错误

/usr/bin/ld: /usr/lib/debug/usr/lib/i386-linux-gnu/crt1.o(.debug_info): relocation 0 has invalid symbol index 11
/usr/bin/ld: /usr/lib/debug/usr/lib/i386-linux-gnu/crt1.o(.debug_info): relocation 1 has invalid symbol index 12
...

这是我的CMakeLists.txt

cmake_minimum_required(VERSION 2.8)
option(test "Build all tests." OFF)
set(EXECUTABLE_NAME MyProj)
project(${EXECUTABLE_NAME})
set(CMAKE_CXX_FLAGS "-g -Wall")

            ${Boost_INCLUDE_DIRS}
            )
find_package(OpenCV REQUIRED)
find_package(Boost REQUIRED COMPONENTS filesystem 
                    system 
                    regex 
                    program_options)
add_executable(${EXECUTABLE_NAME}_Sol2 
              src/main/cpp/main.cpp
              src/main/cpp/solution2/MySol2.hpp
              src/main/cpp/solution2/MySol2.cpp
              )

                        ${Boost_LIBRARIES}
                        )
if (test)
  find_package(GTest REQUIRED)
  enable_testing()
  include_directories( ${GTEST_INCLUDE_DIRS} )
  add_executable(${EXECUTABLE_NAME}_Sol2_test 
            src/test/cpp/test_Sol2.cpp
            src/main/cpp/solution2/MySol2.hpp
            src/main/cpp/solution2/MySol2.cpp
            )

  target_link_libraries(${EXECUTABLE_NAME}_Sol2_test    ${OpenCV_LIBRARIES}
                            ${Boost_LIBRARIES}
                            )
  target_link_libraries(${EXECUTABLE_NAME}_Sol2_test    ${GTEST_LIBRARIES}
                            pthread
                            )
  add_test(${EXECUTABLE_NAME}_Sol2_test 
          ${CMAKE_CURRENT_BINARY_DIR}/${EXECUTABLE_NAME}_Sol2_test
          )
endif()

谁能告诉我一些方法来解决它?

Answer 1

"opencv_ts"模块包含gtest，所以你可以只包括所需的OpenCV模块排除"ts"模块而不是所有。例如:

find_package(OpenCV REQUIRED core imgproc highgui)

Answer 2

添加我需要的lib，比如

target_link_libraries(${EXECUTABLE_NAME}_Sol2   opencv_core
                                                opencv_highgui
                                                opencv_imgproc
                                                ...
                       )
