QuartusII 15.1 - 'GLIBCXX_3.4.20' not found

Published on 10 September 2016 by Gilles Lasnier

If you are using the ALTERA QuartusII 15.1.2 from a Terminal (command line) with an upgraded environment based on Ubuntu 16.04 LTS you may notice some missing libraries:

gil@ciele:~$ quartus
/media/gil/ciele-hdd/tools/altera-install/15.1/quartus/linux64/ version `GLIBCXX_3.4.20' not found (required by /usr/lib/x86_64-linux-gnu/
Failed to load module: /usr/lib/x86_64-linux-gnu/gio/modules/
Inconsistency detected by dl-close.c: 811: _dl_close: Assertion `map->l_init_called' failed!

(quartus:31123): Gtk-WARNING **: Error loading theme icon 'dialog-warning' for stock: Unable to load image-loading module: /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders/ /media/gil/ciele-hdd/tools/altera-install/15.1/quartus/linux64/ version `CXXABI_1.3.8' not found (required by /usr/lib/x86_64-linux-gnu/

The main reason is that your system has a more up-to-date Glibc library than the one provided by the Quartus environment at altera/15.1/quartus/linux64.

You can check on your system and see that the GLIBCXX_3.4.20 library is present by using:

gil@ciele:~$ strings /usr/lib/x86_64-linux-gnu/ | grep 'GLIBCXX'

One quick fix is to replace the one used by Quartus by the one coming from your system:

gil@ciele:~$ cd altera/quartus/15.1/linux64
gil@ciele:~$ mv
gil@ciele:~$ ln -s /usr/lib/x86_64-linux-gnu/

Then relaunch your Quartus.
