我一直在尝试编译我的项目,但在尝试编译时遇到了一些问题。出现的错误尤其是: [build] /usr/bin/ld: CMakeFiles/robot_control.dir/main.cpp.o:(.data.rel.ro._ZTVN4comm15cameraInterfaceE[_ZTVN4comm15cameraInterfaceE]+0x10): undefined reference to `comm::Interface<cv::Mat>::callbackMsg()' 我...

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：
