As it is mentioned in the manual, when you use "guix build -f", the file *must* evaluates to the package definition, i.e. it would work if the last expression in "gnu/packages/emacs.scm" returned a package. But the last expression is ‘(define-public ...)’ which doesn't return a package definition. > by the way, pre-inst-env is not suit my need, I just want to hack a > small package -> rebase it to latest git commit -> test build and > install -> format patch > > The problem is that, when I git pull to get latest git commit, test > build and install need download and build many many package, this is > veeeeeeery sloooooooooow. so I need a way I can code in guix git repo > and use system guix to test build and install. Well, if you don't want to pull the latest commit, use whatever commit you want, modify the package and use "pre-inst-env". I don't really understand what is the problem. Actually, if you really want to use "-f" option, just put ‘emacs-exwm-x’ symbol to the end of that file. But this is not the "right way" :-) -- Alex
