Unsolved pcap.h on a raspberry using qt with cross compil

[jackyPITCH]

Hello !

I want to know what can i do to use pcap.h on a raspberry with qt. I'm developping on a windows machine, using cross compilation to make it readable by the raspberry.
any ideas ? thanks

Hi and welcome to devnet,

Did you install the dev package matching that library on the RPi ?

Hi, thanks ! : )

Yep i did it with

sudo apt-get install libpcap-dev

But when i include my pcap.h file in my qtproject, it is not recognized as known :

pcap.h : No such file or directory

It seems to be normal because it is not installed on the machine i'm developping with, but i dont know how to do.
Also i read somewhere that i have to add this line to my .pro :

LIBS += -lpcap

but an other error pops :

cannot find -lpcap

Did you do that on your Desktop machine ?
