【问题描述】:
我正在尝试对我的应用程序进行一些 Google 测试,但遇到了 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 用于opencv_ts 库。有谁知道如何解决这些多重定义?
我认为如果我只添加我从OpenCV 使用的库,它将得到解决,但我不知道该怎么做。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 ${OpenCV_LIBS_DIR}/opencv_core.so* ... )
等,但我得到的只是未找到或No rule to make tarket的错误
我试图删除两者之一,但我得到了
的错误/usr/bin/ld: /usr/lib/debug/usr/lib/i386-linux-gnu/crt1.o(.debug_info): relocation 0 has invalid symbol index 11
/usr/bin/ld: /usr/lib/debug/usr/lib/i386-linux-gnu/crt1.o(.debug_info): relocation 1 has invalid symbol index 12
...
这是我的 CMakeLists.txt
cmake_minimum_required(VERSION 2.8)
option(test "Build all tests." OFF)
set(EXECUTABLE_NAME MyProj)
project(${EXECUTABLE_NAME})
set(CMAKE_CXX_FLAGS "-g -Wall")
include_directories( src/main/cpp
${Boost_INCLUDE_DIRS}
)
find_package(OpenCV REQUIRED)
find_package(Boost REQUIRED COMPONENTS filesystem
system
regex
program_options)
add_executable(${EXECUTABLE_NAME}_Sol2
src/main/cpp/main.cpp
src/main/cpp/solution2/MySol2.hpp
src/main/cpp/solution2/MySol2.cpp
)
target_link_libraries(${EXECUTABLE_NAME}_Sol2 ${OpenCV_LIBS}
${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()
谁能告诉我一些解决方法?
【问题讨论】:
-
您可以使用 cmake-gui 取消选择 OpenCV 的配置 BUILD_opencv_ts 并重建 OpenCV。然后再试一次。
-
作为你的make错误,我认为你最好把你的cmake文件粘贴出来。
-
我已经添加了cmake文件
