Hi Octavio, I have experienced the same issue when I tried to install NEKTAR on Ubuntu 20.0. I suggest installing it on Ubuntu 18.04 instead. I think the new versions of GCC are not compatible with NEKTAR. Cheers, Mahdi ________________________________ From: nektar-users-bounces@imperial.ac.uk <nektar-users-bounces@imperial.ac.uk> on behalf of Octavio Morales <oct_amg1289@hotmail.com> Sent: 17 October 2020 00:51 To: nektar-users@imperial.ac.uk <nektar-users@imperial.ac.uk> Subject: [Nektar-users] Installation help.
