libstdc++.so.6: version `GLIBCXX_3.4.21' not found error

Question

I am trying to run swift 3.0 on debian 8(Jessie). However, I don't think there is the required version of libstdc++.so.6 file on my laptop. I typed "locate libstdc++.so.6" in the terminal. Below are the responses I get back in the terminal.

/usr/lib/i386-linux-gnu/libstdc++.so.6
/usr/lib/i386-linux-gnu/libstdc++.so.6.0.20
/usr/lib/x86_64-linux-gnu/libstdc++.so.6
/usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.20
/usr/share/gdb/auto-load/usr/lib/i386-linux-gnu/libstdc++.so.6.0.20-gdb.py
/usr/share/gdb/auto-load/usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.20-gdb.py

I also typed "whereis GLIBCXX_3.4.21" in the terminal, and get

GLIBCXX_3.4:

I have also tried

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

Besides that, I also tried

strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX

GLIBCXX_3.4.17
GLIBCXX_3.4.18
GLIBCXX_3.4.19
GLIBCXX_3.4.20
GLIBCXX_DEBUG_MESSAGE_LENGTH

Is there any other way to fix it? Thanks!

Answer 1

Well, I asked this question myself. I just downloaded the snapshot from Apple's official website. The thing was that I was following a tutorial which tied to download the snapshot for ubuntu via wget, but I got the snapshot for ubuntu 15 instead of the one for ubuntu 14. My guess is that ubuntu 15 is newer and therefore it has a newer version of the thing I asked....
