GLIBCXX_3.4.20 not found, how to fix this error?

Whey I try to run the program Layout Editor (available on this site) on Ubuntu 14.04.1 64-bit LTS I get the following output in the terminal:

$ layout
layout: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by layout)

I tried the command strings on /usr/lib/x86_64-linux-gnu/libstdc++.so.6 as following and here is the input and the output:

$ strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX
GLIBCXX_3.4

GLIBCXX_3.4.18
GLIBCXX_3.4.19

How can I resolve this issue I somehow guess that it is related with GCC but cannot figure out how to fix the problem. Furthermore, I have tried a PPA as suggested on How do I use the latest GCC on Ubuntu? and there is a similar question for an older version of Ubuntu at GLIBCXX_3.4.15 not found. However, after I ran sudo update I get numerous warnings and the list I obtained with the strings command did not have new entries after installing gcc 4.9, so I purged the PPA(Toolchains Test Builds) with ppa-purge. Any help, suggestions on how to proceed are greatly appreciated.

Solution 1:

I was having the same problem when trying to run other program, and found a solution on StackOverflow.

Basically, just do the following commands: Firstly, install:

sudo apt-get install libstdc++6

This should already be installed by default, but try it anyway. If it doesn't solve it, just do the following:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test 
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

I didn't perform the "dist-upgrade" command, but the ones before solved it for me

Solution 2:

It happened to me with anaconda 4.0.0 (as @mjp stated), but the fix for me was to run this command in my environment:

conda install libgcc

Solution 3:

I had this issue - it was because Anaconda2 didn't have the GLIBCXX_3.4.20 version of whatever that thing is. Only up to .19, the same as yours.

However, Ubuntu's library did have it. So I just created a softlink/shortcut in the Anaconda library to the actual Linux library containing that GLIBCXX_3.4.20, replacing the previous one, and it worked fine after restarting the python GUI (Spyder).

There should be a folder called libstdc++.so.6 in the Anaconda library, which is here: ~/anaconda2/lib. Within this folder is the versions of the script/library-code-thing, excluding the one that you're missing: GLIBCXX_3.4.20

Follow these steps to solve the issue:

1. go to the right location and backup your current anaconda2 shortcut (change its name so it isn't overwritten):

   cd ~/anaconda2/lib
   mv -vf libstdc++.so.6 libstdc++.so.6.old
   

2. create a new shortcut using the ln command (I am assuming that I am in the previous location ~/anaconda2/lib):

   ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 ./libstdc++.so.6
   

3. restart spyder / other interface you use

It should now work!
