More information
Thanks for changing the title of the thread for me. (I set it as my job title Senior Engineer)
I am a scientist at the Air Force Research Lab. We have a Emulab cluster (a network emulation super computer). The native operating system is FreeBSD 7.4 and I need to port in a variety of appliations: Click Router with MadWiFi driver, WireShark, Iperf, CORE, MATLAB, and OPNET to name a few. Both Windows and linux operating systems are also available.
I started with Click and downloaded the skeleton from FreeBSD and finally found the proper (I think) release of Click and got it in the right directory.
The compilation stopped with a message that there was no rule to build /usr/src/sys/kern/vnode-if.pl, however, there was a vnode-if.src in that directory.
I googled and found that this was a common problem around the time of the release of 7.4 but couldn't find a reference I could understand.
