Eclipse + libpcap network development engineering configuration problems-General Linux technology-Linux programming and kernel information, the following is a detailed description. I want to use eclipse + libpcap as a packet capture tool, so I first wrote a test program.
The terminal displays "undefined reference to 'pcap _ lookupdev'" during Eclipse compilation, that is, the function is not defined. However, I have added pcap. h and can enable it.
If g ++ test. cpp is compiled on the super terminal, the same error is displayed. on the Internet, g ++ test. cpp-lpcap should be used. The compilation was successful.
We are not sure what the use of the lpcap is. Is there any way to enable the app-lpcap feature during Eclipse compilation?
