I have been having issues extracting VMAPS with the 3.3.5a branch, I have tried updating, and rebuilding the source several times, as well as searching the forums and FAQs. As yet I have not been able to track down a solution for this problem. Below is the output of the command string:
$ sudo /home/wow/server/bin/vmap4extractor
