"It appears that 5.23 maxima from 2011 is the latest easily installable version for centos 6."
can we get support for this version?
Forgot to mention that I am talking about STACK here. STACK requirements are for Maxima 5.25.1,to 5.31.3. However in the docs for STACK it says "Please contact the developers to request support for other versions."
RHEL 6 has (through the EPEL repository) version 5.25.1. That is what the OU uses, and is probably the only reason such an old version is still supported by STACK.
And, I am pretty sure some things don't work right there, but they don't cause us problems.
Initially, supporting an older version is probalby as simple as hacking the array in question/type/stack/settings.php to include the version number you want. However, that is no guarantee it will work. After you have done this, you should run
Are you sure about that version number? I just checked on our CentOS server and the latest version on EPEL was 5.23.2-1.el6.
No, I am not sure. I am sure now that I have checked.
The OU is running Maxima 5.23.2, and that is supported.
I just want to interject that problems with using an old version of Maxima, such as 5.23, don't show up immediately. But if you run the full set of tests that STACK provides (beyond the "healthcheck") you will find problems, and they do cause actual trouble for students.
And thank you to Daniel Thies for suggesting a fix by compiling and installing a new Maxima. I haven't tried it yet...
Thank you Peter for posting this link. I've added a note to the documentation on the install page to make it clear that there are real differences in Maxima versions and that this version number requirement isn't just spurious or overly conservative.
