What I know is when you create a package then you can use rosmake to compile.

1.3 Building your nodes
You need to edit you CMakeLists.txt

To build a library take a look at 1.2 Building a library

the problem with this tutorial is that the the classes contains main function, but in my case they don't have any main function.

The only way i found is answered above.

please note that in c++ programming you need to have a main function (it is always the first function to be executed). if you are new to c++ there is a good introduction tutorial on www.cplusplus.com (http://www.cplusplus.com/doc/tutorial/)

Thanks for you reply, i have experience with the c++, but i was studying the RaySensor( Sensor for laser ) and there is no main function in the full hierarchy. i think you have an experience with making sensors if i am not wrong...

The only way to have no main (besides some lowlevel stuff) is, when you build a library.

Thanks for your answer. I got how to compile the single .cpp file without even having no main function.

you have to add two lines to CMakeLists.txt

rosbuild_add_library(gazebo_ros_xx src/gazebo_ros_xx.cpp),

rosbuild_link_boost(gazebo_ros_xx thread)

and then just type the command 'make'.

Hope this will be beneficial to others as well
