Hey guys, 

as it took me a while to install STACK on CentOS 7 and Moodle 3.2 following the steps I took, maybe it helps someone:

  • Check STACK Installation instructions for supported maxima versions: https://github.com/maths/moodle-qtype_stack/blob/master/doc/en/Installation/index.md
  • #On CentOS
yum install gnuplot
yum install maxima



# Install Moodle plugins
git clone git://github.com/maths/moodle-qbehaviour_dfexplicitvaildate.git /var/www/html/moodle/question/behaviour/dfexplicitvaildate
git clone git://github.com/maths/moodle-qbehaviour_dfcbmexplicitvaildate.git /var/www/html/moodle/question/behaviour/dfcbmexplicitvaildate
