如何使用 SFML 和 cmake 進行增強測試？

Question

我正在使用 SFML 在 C++ 中編寫一個簡單的游戲。 我想使用增強測試，但是當我嘗試在我使用 SFML 功能的每個地方獲得未定義的引用時（游戲本身運行良好，只是測試沒有）。 樣品測試：

#include <boost/test/unit_test.hpp>
#include "Sentry.h"

BOOST_AUTO_TEST_SUITE(BasicModelTestSuite)

BOOST_AUTO_TEST_CASE(testLamp_10BulbsWithPower10_ExpectedPower)
    {
        sf::Texture projectileTexture;
        sf::Texture sentryTexture;
        std::vector<std::shared_ptr<Sentry>> foes;
        sentryTexture.loadFromFile("../GameResources/sentry_image.png");
        projectileTexture.loadFromFile("../GameResources/projectile_animation.png");
        foes.push_back(std::make_shared<Sentry>(Sentry(&sentryTexture, sf::Vector2u(1,2), 0.2f, sf::Vector2f(140,200), projectileTexture, true)));
        foes.push_back(std::make_shared<Sentry>(Sentry(&sentryTexture, sf::Vector2u(1,2), 0.2f, sf::Vector2f(200,200), projectileTexture, false)));
        BOOST_REQUIRE_EQUAL(foes.size(), 2);
    }

BOOST_AUTO_TEST_SUITE_END()

以及 cmakelist.txt 的測試部分：

ind_package(Boost 1.65 COMPONENTS "unit_test_framework" REQUIRED)

include_directories(
        ${CMAKE_CURRENT_SOURCE_DIR}/include
        ${Boost_INCLUDE_DIRS}
)

set(SOURCE_TEST_FILES
        test/master.cpp test/master.cpp test/baseTest.cpp
        main.cpp src/Level.cpp include/Level.h src/Game.cpp include/Game.h src/Platform.cpp include/Platform.h src/Item.cpp include/Item.h src/Life.cpp include/Life.h src/Coin.cpp include/Coin.h src/Collider.cpp include/Collider.h src/Enemy.cpp include/Enemy.h src/MrStrawberry.cpp include/MrStrawberry.h src/Animation.cpp include/Animation.h src/MrBerry.cpp include/MrBerry.h src/Projectile.cpp include/Projectile.h src/Sentry.cpp include/Sentry.h)

add_executable(TestProject ${SOURCE_TEST_FILES})

target_include_directories(TestProject PUBLIC include)

target_link_libraries(TestProject
        ${Boost_UNIT_TEST_FRAMEWORK_LIBRARY})

enable_testing()

add_test(NAME Test COMMAND TestProject
        --report_level=detailed
        --log_level=all
        --color_output=yes)

add_custom_target(check ${CMAKE_COMMAND} -E env CTEST_OUTPUT_ON_FAILURE=1 BOOST_TEST_LOG_LEVEL=all
        ${CMAKE_CTEST_COMMAND} -C $<CONFIGURATION> --verbose
        WORKING_DIRECTORY ${CMAKE_BINARY_DIR})

我不知道為什么它會拋出對所有內容的未定義引用，如下所示：

/usr/bin/ld: /home/student/CLionProjects/oop21_ww2_14/BerryGame/src/Projectile.cpp:8: undefined reference to `sf::RectangleShape::setSize(sf::Vector2<float> const&)'
/usr/bin/ld: /home/student/CLionProjects/oop21_ww2_14/BerryGame/src/Projectile.cpp:9: undefined reference to `sf::Shape::setTexture(sf::Texture const*, bool)'

Answer 1

TestProject 在鏈接選項中缺少 SFML 庫（另請參閱什么是未定義的引用/未解析的外部符號錯誤以及如何修復它？ ）。 您的主要可執行文件顯然有它，但您沒有顯示它。

尋找類似的東西

 LINK_LIBRARIES(sfml-system sfml-window sfml-graphics sfml-audio)

或者改為 target_link_libraries。 如果使用LINK_LIBRARIES ，我想目標可能需要在那之后定義。
