[经验] error: invalid use of non-static member function

error: invalid use of non-static member function ‘void Camcallbackc::camcallbackm(const ImageConstPtr&, const CameraInfoConstPtr&)’
image_transport::CameraSubscriber sub = it.subscribeCamera("/camera/rgb/camera_info",100, Camcallbackc::camcallbackm,  Camcallbackcp);

出错的是这个参数 Camcallbackc::camcallbackm
改为&Camcallbackc::camcallbackm，编译通过。

谢谢分享
