./net/if_arp.hCould you give more information how to port project from Linux to freeBSD?
There is no "one-size-fits-all" tutorial covering this. You're going to need to do a lot of legwork yourself. And this starts by understanding how each system works.
This tells me you have zero experience compiling anything. Let alone porting something from one system to another.
pkg install {de,en}-freebsd-doc, replace de with your native tongue, and point your favorite browser to /usr/local/share/doc/freebsd. There's a Porter's Handbook. message: "query '[%C/%n] %M'",
rmessage: query -i "[%C/%n-%v] %M", pkg message|less.
What kind of project is that, exactly?
It's some custom project for Linux (write on C). And I need to run this executable files on the FreeBSD.
What does it do?
This is where experience comes in. You need to have a good understanding of the code and how it works before you can attempt to port it. Think of it as asking a mechanic friend how to improve the performance of your car without understanding how an engine works. He can tell you but you're not going to understand it.
That depends on the project and how it's set up. Sometimes you can but most of the time your going to need to patch the code. Again, this is where experience comes in, if you know and understand what the code does you will know exactly what needs to be changed.
sysrc linux_enable=YES. For some you need to mount Linux proc, sys or /dev/shm (or all of these) filesystems. /etc/fstab:linproc /compat/linux/proc linprocfs rw 0 0
linsys /compat/linux/sys linsysfs rw 0 0
tmpfs /compat/linux/dev/shm tmpfs rw,size=8G,noexec,mode=1777 0 0"Custom project" is too vague for an answer.
Do you mean that possible to compile it on the centOS and try to run on freeBSD?
I really don't know very well how this code works. For me, I need compile it and run on freeBSD. I know, this code sends some data to the server.
That's still too vague to make a proper assessment of the work that may need to be done.
I'll try to compile it on the centOS and Ubuntu and will give answer tomorrow.
Long story short (answer from Radio Yerevan): Yes, BUT if it needs some exotic library that you can not find in any of the linuxXYZ-c7 ports/packages, then you'll have to use archivers/rpm4 to install them and I strongly suggest to set up a Linux jail inside your FreeBSD host for that. Build your project on a "real" CentOS 7. Do not compile in a standard Linux jail. That would need a special setup. It's possible, though. CentOS 7 in a bhyve(8) VM should be fine.
You still fail to answer what the actual purpose of the software is.
This is no hack software. This absolutely legal software. But this software from my work, for commercial project. Sorry, I can't due to NDA tell more about it.
