That's a very simple patch that one of us could apply. But in all honesty I don't think it makes sense to add sub-releases like this. The only thing that will fix the problems with gcc 5.x in the long run is newer version of gf2x and ncurses that can deal with it out of the box. In that context I

Thanks, Anne, for your interest. I've never taught out of Artin, and my copy is not here at home. But I'll say that Tom's book is very much like Gallian's, which I used for many years. Tom has also used it for a graduate course. And there are a few Sage examples with a distinctly combinatori

Dear Rob, This looks like a great book! I will be teaching Abstract Algebra at UC Davis in the fall and will try to use it (along with Artin's book). How does it compare to Artin "Algebra", besides offering many Sage examples? Best wishes, Anne On Wednesday, July 29, 2015 at 6:32:36 PM UTC-7,

Hello leif, I'm using gcc 5.2.0 under ArchLinux. Issues with ncurses and gf2x remain. I've created and tested a patch (attached) to extend some of the existing fixes for gcc 5.0 and 5.1. A post at sage-support [1] might also be relevant. Best, Fidel [1]: https://groups.google.com/d/topic/sage
