Thank you for getting back to me! The weird Unicode double quote characters are unfortunately an artifact of the text editor I used. I missed spotting that the editor automatically replaced my normal plain double quotes with the Unicode ones, I’m very sorry for that. :(
It turned out that the Guile support was not correctly built, but this put the finger on something else that I’m not sure is an intended feature or a bug. What I’m talking about is that if you try using a non-existent function, say like I do in this makefile where fnord is not defined/known by GNU Make > $ cat Makefile > > FOO = $(fnord "F N O R D") > $(info $$FOO is [$(FOO)]) > > fnord: ; for i in "$(FOO)"; do echo $$i; done > > $ make I get the exact same behavior I reported in my issue. So my question is really if this behavior is documented somewhere? Shouldn’t GNU Make raise an error when a make file calls a non-existing function? If it is not possible to have GNU Make by default raise an error when this happens due to backward compatibility concerns, what about a configuration option (command line and/or configurable from within makefile by setting some value)? If I had to choose between the two approaches I would prefer the one where you configure behavior from within makefile. > > On 2 Jan 2023, at 06:28, Paul Smith <psm...@gnu.org> wrote: > > On Wed, 2022-12-14 at 13:12 +0100, johol wrote: >> FOO = $(guile (fnord “F N O R D”)) > > I'm not sure what environment you're using, but my version of Guile > doesn't work with these special UTF-8 quote characters you're using > here: “ and ”. > > When I try to use them, and the sample makefile you've provided, I get > all sorts of bizarre errors from the Guile interpreter. > > If I replace these characters with standard ASCII double-quote > characters " then it seems to work fine: > > $ cat Makefile > define FNORD > ;; Simple initial Guile-test > (define (fnord value) > value) > endef > > # Internalize the Guile code > $(guile $(FNORD)) > > FOO = $(guile (fnord "F N O R D")) > $(info $$FOO is [$(FOO)]) > > fnord: ; for i in "$(FOO)"; do echo $$i; done > > $ make > $FOO is [F N O R D] > for i in "F N O R D"; do echo $i; done > F N O R D > > If you don't see this behavior you'll need to provide more details such > as which version of Guile you compiled with.
