Hi, I'm having trouble getting the sagemath gap interface to work on my system. Here's some of the output I get when trying to use the all subgroups functionality.

sage: S5 = SymmetricGroup(5)
sage: S5
Symmetric group of order 5! as a permutation group
sage: sg = S5.conjugacy_classes_subgroups()
This workspace is not compatible with GAP kernel (4.10.0, present: 4.10.1).

I have GAP Version 4.10.1 and Sage 8.7 installed.

I've not seen any other people with this issue post about it before, any ideas on what I may be doing wrong?

What operating system? How was Sage installed?

This is on Arch linux, installed using pacman. (

I also tried to use sage -i database_gap make: * No rule to make target 'all-toolchain'. Stop.

It says on the archwiki that this command will not work if you install sage as I did using pacman, maybe there is a work around to use this command on arch?

I have similar issues on sage -i gap_packages too! Error: * No rule to make target 'all-toolchain'. Stop. I'm also on Arch linux, installed via pacman. @skafiskafniak have you figured out a solution?

Seems you have a stale GAP workspace - can you try deleting ~/.sage/gap ?

same problem here on manjaro (arch based linux distribution), the above solved the issue, thanks @arojas!
