Hello, I wish to share how I got this working:
I wanted to do command: guix edit mutt only that one could not edit the file, so I have saved the file locally. Andreas Enge pointed that I have to do following: From: Andreas Enge To: Jean Louis Cc: 22970-d...@debbugs.gnu.org, help-guix@gnu.org Subject: Re: bug#22970: guix edit mutt -- not working On Thu, Mar 10, 2016 at 12:22:20AM +0100, Jean Louis wrote: > And I could not save the file in my home directory, and do: > guix package -i mutt -f mail.scm As mentioned on IRC, modify the file mail.scm by adding a line mutt at the end. Then guix package -f mail.scm does "install the package that the code within FILE evaluates to" as explained by "guix package --help". mail.scm itself does not evaluate to anything, it just contains a number of variable definitions. By adding the line, it "returns" the value of the variable mutt, which is your package definition. Better yet, use GUIX_PACKAGE_PATH, for instance as follows: export GUIX_PACKAGE_PATH=$HOME/guix Then create the same file layout in that directory as in the source code: mkdir -p $HOME/guix/gnu/packages Copy mail.scm there, modify mutt, then guix package -i mutt will first look for your modified package. So, I have done that with file: ~/gnu/guix/packages/mutt.scm which is attached. And I have added, dependency "gdbm" for the option --enable-hcache to have it working: (inputs `(("cyrus-sasl" ,cyrus-sasl) ("gpgme" ,gpgme) ("gdbm" ,gdbm) and `(#:configure-flags '("--enable-smtp" "--enable-imap" "--enable-pop" "--enable-gpgme" "--enable-hcache" Jean Louis
