如何修复来自glad.c的对符号“dlclose@@GLIBC_2.2.5”的未定义引用[重复]

我正在按照以下教程学习 Openglhttps://learnopengl.com/ https://learnopengl.com/我在使用 cmake 设置依赖关系时遇到问题（请参阅创建窗口 https://learnopengl.com/Getting-started/Creating-a-window).

我的 CMakeLists.txt 基于GLFW 文档 https://www.glfw.org/docs/latest/build_guide.html#build_link_cmake_package.

cmake_minimum_required(VERSION 3.14)
project(openglTuto)


include_directories(include)
add_executable(gltuto src/main.c src/glad.c)

find_package(glfw3 3.3 REQUIRED)
find_package(OpenGL REQUIRED)

target_link_libraries(gltuto glfw)
target_include_directories(gltuto PUBLIC ${OPENGL_INCLUDE_DIR})
target_link_libraries(gltuto ${OPENGL_gl_LIBRARY})

CMake 成功构建了我的配置，但 ninja 无法编译并打印错误。

[1/1] 链接 C 可执行文件 gltuto

失败：饕餮 ：&& /usr/bin/cc CMakeFiles/gltuto.dir/src/main.c.o CMakeFiles/gltuto.dir/src/glad.c.o -o gltuto /usr/lib/libglfw.so.3.3 && ：

/usr/bin/ld：CMakeFiles/gltuto.dir/src/glad.c.o：对符号“dlclose@@GLIBC_2.2.5”的未定义引用

/usr/bin/ld: /usr/lib/libdl.so.2: 添加符号时出错：命令行中缺少 DSO

collect2：错误：ld 返回 1 退出状态

ninja：构建停止：子命令失败。

链接器抱怨找不到dlclose。 你可以加libdl with CMAKE_DL_LIBS https://cmake.org/cmake/help/v3.14/variable/CMAKE_DL_LIBS.html。 此外，利用现代链接targets代替strings.

将您的 CMakeLists.txt 更改为：

cmake_minimum_required(VERSION 3.14)
project(openglTuto)


add_executable(gltuto src/main.c src/glad.c)

find_package(glfw3 3.3 REQUIRED)
find_package(OpenGL REQUIRED)

target_include_directories(gltuto PUBLIC
                           $<BUILD_INTERFACE:${CMAKE_CURRENT_LIST_DIR}/include>
                           $<INSTALL_INTERFACE:include>)
target_link_libraries(gltuto PUBLIC glfw OpenGL::GL ${CMAKE_DL_LIBS})

Look up 生成器表达式 https://cmake.org/cmake/help/v3.14/manual/cmake-generator-expressions.7.html?highlight=generator%20expressions去理解BUILD_INTERFACE and INSTALL_INTERFACE.
