cantera installation on ubuntu

[refikalp...@gmail.com]

Hello,

I have been trying to install cantera on ubuntu 20.04 LTS.

So far, i "git-cloned" cantera to a folder cantera on ubuntu as instructed online.

I used " scons build" and "scons test" without error. And when i try to run "scons install" i get following errors:

scons: Reading SConscript files ...
INFO: SCons is using the following Python interpreter: /usr/bin/python3
Configuration variables read from 'cantera.conf' and command line:

What should i do to overcome these errors ?

Can i get some light on this ?

Best regards.

Hi,

The /usr/local directories are protected from writing by normal users. You need to give yourself permission to modify those folders by using the "sudo" prefix for a command.

sudo scons install

Best,

Bryan
