c++ - 对`testing::UnitTest::Run() 的未定义引用

问题描述

不同的存储库映像

add_executable(test_labyrinthe test_labyrinthe.cpp)
add_test(test_labyrinthe.cpp test_labyrinthe)
target_link_libraries(test_labyrinthe ${GTEST_LIBRARIES})

这就是我在 Test/CMakeLists.txt 中的内容

cmake_minimum_required(VERSION 3.5)
project(TP1)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

set(SOURCE_FILES
    Labyrinthe.cpp
    Labyrinthe.h
    Piece.cpp
    Piece.h
    Porte.cpp
    Porte.h
    Principal.cpp)

add_executable(TP1 ${SOURCE_FILES})


###########
## GTEST ##
###########

option(BUILD_TESTING "build unit tests" ON)

if(BUILD_TESTING)
  include(ExternalProject)

  ExternalProject_add(gtest-target
    GIT_REPOSITORY "https://github.com/google/googletest"
    CMAKE_ARGS "-DCMAKE_INSTALL_PREFIX=${CMAKE_CURRENT_BINARY_DIR}/extern"
    UPDATE_COMMAND ""
  )

  include_directories(${CMAKE_CURRENT_BINARY_DIR}/extern/include)
  link_directories(${CMAKE_CURRENT_BINARY_DIR}/extern/lib)
  set(GTEST_LIBRARIES pthread gtest gmock gtest_main gmock_main)

  enable_testing()

  add_subdirectory(test)
endif()

这就是我的主要内容CMakeLists.txt。请记住，我只有#include <gtest/gtest.h>.test_labyrinthe.cpp

当我跑步时cmake ..，make我得到了

make: *** [Makefile:95: all] Error 2

这真的很奇怪。不知道如何使这项工作。你能帮我吗？

编辑当我跑步时make test，我得到了

解决方案

经过无数次尝试后，解决方案是添加-pthread如您在此处看到的：

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -pthread")
