Same question trying to compile the TL-WN725N Wifi driver.

root@raspberrypi:~/# apt-get install linux-headers-$(uname -r)

E: Unable to locate package linux-headers-3.18.7
E: Couldn't find any package by regex 'linux-headers-3.18.7'
root@raspberrypi:~/# uname -r
3.18.7+

Where to get that headers?
