【问题描述】:
我正在尝试使用 GoogleTest 对函数进行测试,但现在它不再找到 EqFailure 事物:
/usr/include/gtest/gtest.h:1337: undefined reference to `testing::internal::EqFailure(char const*, char const*, testing::internal::String const&, testing::internal::String const&, bool)'
我正在编写这样的测试:
test_file.cpp:
#include <gtest/gtest.h>
#include "tools/CMorphology.hpp"
TEST(erode_Morph, crossKernel_Morph)
{
// initialize matrix to be eroded
cv::Mat matrix = (cv::Mat_<uchar>(5, 5) << 1, 1, 1, 1, 1,
1, 1, 0, 1, 1,
1, 1, 1, 1, 1,
1, 0, 1, 1, 1,
1, 1, 1, 1, 1
);
// initialize the cross kernel
cv::Mat kernel = cv::getStructuringElement(cv::MORPH_CROSS, cv::Size(3, 3));
// initialize the vector expected as output
cv::Mat verMat = (cv::Mat_<uchar>(5, 5) << 1, 1, 0, 1, 1,
1, 0, 0, 0, 1,
1, 0, 0, 1, 1,
0, 0, 0, 1, 1,
1, 0, 1, 1, 1);
// call erode(...)
Morphology morphology;
cv::Mat matrixOut;
morphology.erode(matrix, kernel, matrixOut);
for (int i = 0; i < matrixOut.rows; i++)
{
for (int j = 0; j < matrixOut.rows; j++)
{
EXPECT_EQ(matrixOut.ptr<uchar>(i)[j], verMat.ptr<uchar>(i)[j]);
}
}
}
我正在使用 OpenCV,如果需要,我会发布其他文件。
CMake 文件在这里:
cmake_minimum_required(VERSION 2.8)
set(EXECUTABLE_NAME lpdetect)
project(${EXECUTABLE_NAME})
option(DEBUG "Display images for each step" OFF)
if (DEBUG)
set(CMAKE_CXX_FLAGS "-g -Wall -Wno-unknown-pragmas -Wno-reorder -Wno-sign-compare -Wno-switch -std=gnu++11 -DDISPLAY_IMGS -DBOOST_LOG_DYN_LINK")
else()
set(CMAKE_CXX_FLAGS "-g -Wall -Wno-unknown-pragmas -Wno-reorder -Wno-sign-compare -Wno-switch -std=gnu++11 -DBOOST_LOG_DYN_LINK")
endif()
find_package(OpenCV REQUIRED core
imgproc
features2d

highgui
)
find_package(Boost REQUIRED COMPONENTS filesystem
program_options

)
include_directories(src/main/cpp
${Boost_INCLUDE_DIRS}

add_executable( ${EXECUTABLE_NAME}
src/main/cpp/main.cpp
# and the other files
)
target_link_libraries(${EXECUTABLE_NAME} ${OpenCV_LIBS}
"-laws-cpp"
"-lcasablanca"
${Boost_LIBRARIES}
"-lcrypto"
)
find_package(GTest REQUIRED gtest_main
pthread)
enable_testing()
include_directories( ${GTEST_INCLUDE_DIRS} )
add_executable(${EXECUTABLE_NAME}_test src/test/cpp/test_Morphology.cpp
src/main/cpp/tools/CMorphology.cpp
src/main/cpp/tools/CMorphology.hpp
)
target_link_libraries(${EXECUTABLE_NAME}_test
${OpenCV_LIBRARIES}
${Boost_LIBRARIES}
${GTEST_LIBRARIES}
)
add_test(${EXECUTABLE_NAME}_test
${EXECUTABLE_NAME}_test
)
我很久以前就做过这个,在一些提交之后它显示了这个错误。为什么它不再发现?
【问题讨论】:
-
您可以尝试详细运行您的构建,并查看包含您的 gtest 库的目录是否有
-L链接目录选项?你是静态链接还是动态链接?错误发生在链接时(不是运行时),对吗? -
它发生在链接时,是的。我动态链接了它
-
应该是
Gtest_LIBRARIES而不是GTEST_LIBRARIES?我对cmake不太熟悉,但基本思想是cmake应该在命令行上生成一个-lgtest,并且可能生成一个-L/path/to/gtest。你能看看这是否是你的链接命令行的一部分吗?可能相关:stackoverflow.com/questions/8507723/…
