The pfSense PHP code isn't code that can be "compiled" in that way. It won't work on Windows either.

pfSense is its own operating system. If you are trying to build a custom image, that must be done in FreeBSD using all of the necessary repositories (pfSense, freebsd-ports, freebsd-src).

@jimp u mean that i must used freeBSD operating system
i don't get it

What exactly are you trying to do?

What is your goal?

@Tewodros : Fire up www.google.com and ask the right question.
You'll find info like https://github.com/PiBa-NL/PiBa-NL-WIKI/wiki/How-to-building-a-pfSense-.iso-from-sources with many answers.
Still, building OS's yourself presumes that you all ready know the basics needed to do such a thing.
