Hola a todos !
Primero, felicidades por la web, es genial y se aprende un monton !
Os cuento, estaba yo con el wlainject, a ver si lo puedo instalar, y despues de instalar todas las librerias que me iba pidiendo y leer muuuuuuchos post, me he quedado encallado aqui:

sudo make

gcc -Os -I. -lnet -lpcap -W -Wall  -MMD    -c wlaninject.c

make: *** [wlaninject.o] Error 1

Ya no se que hacer, y ya he hecho: sudo apt-get build-dep aircrack-ng; sudo apt-get install -y libnet0 libnet1 libnet1-dev libpcap0.7 libpcap0.7-dev libpcap0.8 y tengo instalado el ultimo libnet y el libpcap 0.8.1 ....

Alguna idea ???

GRACIAS !

ubuntu o debian?

reinstala libnet y libnet-dev a ver

bt4 es ubuntudebian asi que no deberias de tener problemas

pega exactamente error

los signos esos no dan buen rollo 

reinstala libnet y libpcap con apt o a mano
y recompila usando antes make clean && make && make install

como no va a llevar libpcap una distro como BACKTQRACK de auditorias?¿
