In the IRC-channel, I was told that the undocumented, magic %output
variable is deprecated. Instead, I should use #$output. But I couldn't
get this done. I always ran into strange errors.
How should I change the following snippet?
--8<---------------cut here---------------start------------->8---
(arguments
'(
#:tests? #f ; no tests
#:make-flags (list "CC=gcc")
#:phases
(modify-phases %standard-phases
(delete 'configure)
(add-after 'unpack 'patch-makefile
(lambda _
(substitute* "Makefile"
(("/usr/local") %output)))))))
--8<---------------cut here---------------end--------------->8---
