How can i install, from packages, Boost 1.55 on Ubuntu 15.10? For example, the repository (via Synaptic) only shows Boost 1.58 only, and Emulationstation (the version i have as tarball) uses Boost 1.55 as dependency - i have 1.58 installed, and terminal shows "emulationstation: error while loading shared libraries: libboost_system.so.1.55.0: cannot open shared object file: No such file or directory"
This can be really bad for your system.
The best thing to do is to clone the source code and compile it yourself.
(it doesn't look that hard: https://github.com/Aloshi/EmulationStation)
But if for some reason you really want to install an old version of libboost you can do it that way:
(I really don't recommend doing that unless you know what you're doing,
you can damage your system)
Download from here the packages suitable for your OS:
Ror 64bit download
For 32bit download
If you run something else download
If it's available in your current
apt sources, you can install it using the below steps:
sudo apt-get install libboost1.55*
If prompted type in your password (When you type in your password nothing will show up, this is normal)
If prompted type
yto confirm that you want to install it.
Profit! If all went well, then congrats! You successfully installed it!
