Error Building Pyrit On CentOS: cpyrit/_cpyrit_cpu.c:26:18: error: pcap.h: No such file or directory
When building pyrit, which is an application that uses GPU power to run dictionary attacks against WPA handshake captures, on CentOS Linux I ran into an error. The error was related to the pcap.h library which was not found by the pyrit setup.py python script. Resolving the problem is easy by simply installing the libpcap-devel RPM package using the yum package manager. Below I display more output surrounding the error, the log showing the libpcap-devel package installation, and finally the successful build of pyrit on CentOS Linux.
