How to use <IRremote.h> and <NewPing.h> in one program

Hi !
I want a robot with 2 modes that can be controled by a remote TV.
In mode 1: remote control car and mode 2: obstacles avoiding car
I have write a code of remote and obstacles avoiding. They work fine when I use them in different program. But i put them in one program, I get the following error:

C:\Users\DELL\Desktop\Hex\libraries\IRremote\IRremote.cpp.o (symbol from plugin): In function `MATCH(int, int)':

(.text+0x0): multiple definition of `__vector_7'

C:\Users\DELL\Desktop\Hex\libraries\NewPing\NewPing.cpp.o (symbol from plugin):(.text+0x0): first defined here
