roscpp cannot understand a single cpp keyword

edit

I've written a package and I can succesfully use it's node and i have sended the package to my friend. He wanted to compile my package in his pc by catkin make but faced this error:

metobom@metobom-TULPAR-T5-V17-1:~$ rosrun mpk2 mrc.cpp
/home/metobom/metos_ws/src/mpk2/src/mrc.cpp: line 4: //#include: No such file or directory

/home/metobom/metos_ws/src/mpk2/src/mrc.cpp: line 16: `};'

So what is the actual problem, can he solve it without reinstalling everything.

Thanks for answers im looking forward to solve it.
