The `list` was present. As suggested by Feng Shu in another thread, it
works like this:
--8<---------------cut here---------------start------------->8---
(arguments
(list
#: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---
It also seems to work with:
#:make-flags '(list "CC=gcc")

Do I have to import cc-for-target from (guix utils)?
In case of:
;; do not have (guix utils) imported
#:make-flags (list (string-append "CC=" (cc-for-target)))
I get this during build:
error: cc-for-target: unbound variable
In case of:
;; have (guix utils) imported
#:make-flags (list (string-append "CC=" (cc-for-target)))
I get this error:
Wrong type to apply: "CC=gcc"
In case of:
;; have (guix utils) imported
#:make-flags #~(list (string-append "CC=" (cc-for-target)))
I get this error:
Unbound variable: cc-for-target
In case of:
;; have (guix utils) imported
#:make-flags `(list (string-append "CC=" ,(cc-for-target)))
I get this error ... Oh, wait, it works!
So this is the working code:
--8<---------------cut here---------------start------------->8---
(arguments
(list
#:tests? #f ; no tests
#:make-flags `(list (string-append "CC=" ,(cc-for-target)))
#:phases
#~(modify-phases %standard-phases
(delete 'configure)
(add-after 'unpack 'patch-makefile
(lambda _
(substitute* "Makefile"
(("/usr/local") #$output)))))))
--8<---------------cut here---------------end--------------->8---
Putting the comma like this also seems to work:
#:make-flags `(list (string-append "CC=" ,(cc-for-target)))

I see. Sorry for misunderstanding :-)
