Compile Error

[Stephen Keeler]

I'm using this document to setup a snort / barnyard2 instance and I'm running into a problem compiling barnyard2

http://www.rivy.org/2013/03/building-barnyard2-from-source/

Here's the error that I'm receiving when making from a Ubuntu 14.04LTS system

I'm not sure if I'm missing anything

Seem's like your libpthread is missing pthread_sigmask.

Might want to check if you have a upgrade avail for libpthread on your distro.

Tried installing all of the libpthread packages I could find for Ubuntu and I still have the same error message.

Do you need prelude? if not do a make distclean and re-run configure
without --enable-prelude
