I hope I can turn my current confusion and the notes I am taking to something productive to beginners documentation/guide at some point.
So what happened today was: - I tried the build of the sourcetree described below in some variations. Failed. - I mounted an external disk with what used to be my working repo of the source before I made the decision to not rely on external disks that much. switched to some branch on this disk I was working on, excluding problems with the file I was working on it did theoretically build. Now I wonder what could be the difference? Why does my current checkout fail, but the other one doesn't? iirc the current one went: git clone $url-on-sv-guix git checkout -b wip-lispf4 emacs gnu/packages/lisp.scm and work on that file, save it but not commit guix environment guix (also tried adding git make) make clean-recursive ./bootstrap ./configure --localstatedir=/var make check what would be a simple step by step command list to get to the point of a working branch which can build? I feel like I am asking weird questions and it might be that I just try too much too hard to see where the problem is so that I lost track of the actual problem.
