I see - you don't have a git repository, and you do need one! The quick way to get the patch is as follows: first do, in some other directory, $ git clone http://trac.sagemath.org/sage.git you'll see something like Cloning into 'sage'... remote: Counting objects: 267342, done. remote: Compressing objects: 100% (47582/47582), done. remote: Total 267342 (delta 192114), reused 264313 (delta 189133) Receiving objects: 100% (267342/267342), 76.30 MiB | 20.59 MiB/s, done. Resolving deltas: 100% (192114/192114), done. now you do $ cd sage $ git fetch http://trac.sagemath.org/sage.git u/pbruin/16224-maxima_to_sage $ git merge FETCH_HEAD (the last two steps were already explained) now you copy the patched file in question (src/sage/interfaces/maxima_lib.py) to your working Sage install, go there, run 'sage -b'... If you like to do this on a regular basis then certainly it's better to have Sage compiled from the git repo you just created. > > > > On Mon, Jun 23, 2014 at 2:55 PM, Dima Pasechnik <[email protected]> wrote: > >> On 2014-06-23, Karl Schultheisz <[email protected]> wrote: >> > I have installed git and chosen my name and email address.
