No. You need to compile your program (within the IDE or on the command line), execute, on the command line, the command sudo setcap cap_net_raw,cap_net_admin+eip {your program} where {your program} is the path to the executable that was built, and then you can run the program from the command line or from the IDE. > Alternatively, while I've been happy using CentOS as a development > environment up until now.

Note that, as I said, getting a newer version of libpcap will *not* remove the requirement that you run your program with special privileges; all it means is that pcap_lookupdev() will not require the special privileges, but if you plan to *open* the device that it returns, your program will have to run with, at minimum, the cap_net_raw privileges. And all that choosing a distribution other than CentOS will do is perhaps change the libpcap version. > Basically I would like to be able build and execute within the IDE. Unless you can arrange that the IDE run a special command, *as root*, as part of the build process, you won't be able to do everything within the IDE> The command in question is "setcap cap_net_raw,cap_net_admin+eip {the program that was built}". It will have to ask you for root privileges, which means that, if you want to avoid the command line, the IDE will have to run some GUI program that asks for your password, or the password of somebody with rights to run a program as root (that's what sudo, on the command line, does, but I don't know whether any version of sudo can do a GUI prompt when not run on the command line) and then run a command as root. You will also have to have whatever privileges sudo, or the GUI program, requires you to have in order for it to allow you to run a program as root.
