pcap.h on a raspberry using qt with cross compil



  • 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
