That did the trick. I was able to complete the to create both the debug and release libraries. I was also able to build the demo applications. However when I run ./demo_mn_console. I got a "oplk_create() failed". See below for details.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Please disregard my previous post. I ran "demo_mn_console" with sudo and the "oplk_create() failed" problem went away. The MN under Linux is now communicating with one of the CN under Windows.
Thanks for all your help,

Hi, I am trying to bulld the openpowerlink stack on linux (x86 platform). I followed the instructions:
I completed the "cmake" step without errors. However, when I did "make", I encounter the following:
"fatal error: pcap.h: No such file or directory"
Does anybody know why that is happening?
Thanks,
Simon
Hi Simon,
you're missing libpcap (which is a dependency of openPOWERLINK) on your system. If you use Ubuntu do that:
sudo apt-get install libpcap-devRegards,
Norman
Hi Norman,

Any ideas why this happening? and how to fix it?
