Please help me until then, as your style to make a modified package is excellent for me. I guess you forgot the dependency gdbm, where to put it? (define-module (my-guix-packages) #:use-module (guix packages) #:use-module (guix download) #:use-module (guix utils) #:use-module (gnu packages mail)) (define-public my-mutt (package (inherit mutt) (name "my-mutt") (arguments (substitute-keyword-arguments (package-arguments mutt) ((#:configure-flags cf) `(cons "--enable-hcache" ,cf)))) (synopsis (string-append (package-synopsis mutt) " (configured with --enable-hcache)")))) On Fri, Mar 11, 2016 at 12:21:09PM +0100, Jean Louis wrote: > Hello Alex, >=20 > Thank you much.
