Building libtorrent under CentOS 7?

Question

CentOS

Greetings!
Gentlemen, firstly, I apologize if I ask for help in the wrong place, and secondly, I emphasize that I am absolutely green in Linux'ah.
There was a need to build the current qbittorent for CentOS 7, because the existing package for CentOS is quite dense.
I found an instruction in which there are two stages:
- building libtorrent ;
- build qbittorent.
At the build stage of libtorrent-1.2.0, the following errors got out:

Googled but didn't find any solutions. Help, please, to understand.
Thank you!

Answer 1

For starters, try a more recent tooling (compiler, header files, etc.) for the build.
The second advice - theoretically, if all the dependencies are packed inside, then you can build the library on some kind of ubuntu, and then transfer it to CentOS.

Answer 2

Building anything in centos is such fun that without knowing how programs are built in linux in general, it will turn into a very exciting educational program for learning the compiler, linker, autotools / cmake (depending on what you use), make...
If you don't want to upgrade skills in full immersion mode, look for a third-party turnip where this package is available (someone will probably collect a rather popular package) and connect it. And for starters, connect large third-party turnips like epel, elgis, lux, rpmforge
