然后 #include myClass 来自main.cpp 的unit-test project 的应用程序项目。然后,从 myClass 创建一个 myObject --- 并在该对象中调用一个函数。 编译时出现这个错误: undefined reference to `myObject::function' 但是,当将 #SOURCES applicationProjectPath/myClass.cpp 添加到单元测试项目的 .pro 文件中时...

第三章:设置你的第一个 CMake 项目 现在我们已经收集了足够的信息,可以开始讨论 CMake 的核心功能:构建项目。在 CMake 中,一个项目包含管理将我们的解决方案带入生活的所有源文件和配置。配置从执行所有检查开始:目标平台是否受支持,是否拥有所有必要的依赖项和工具,以及提供的编译器是否工作并支持所需功能。 完成...

class_name is the name of a C++ class, struct, union, or template class.mode specifies how the memory was accessed. It can be composed of one or all of the letters:r The memory at the specified address has been read. w The memory has been written to. x The memory has been ...
cmake 从.cpp文件调用时，无法链接.cu文件中定义的函数在头文件中定义的函数中似乎缺少一个static关键字。这是所有C/C++非模板化函数所必需的，以便将此函数的可见性限制在当前编译单元中，并避免与其他编译单元中包含的相同函数冲突。示例如下：
