This is because (rightfully) the output got a new dependency… > $(MAK_DIR_GITWEB)static/gitweb.js: $(MAK_DIR_GITWEB)generate-gitweb-js.sh … but the rule uses $^ to append sources.

I have no idea, possibly. As a BSD make person I consider use of $^ in nōn-suffix rules generally often problematic… Perhaps test if it indeed works; if it does, choose by whatever is the project-desired style.

The commit message could use a bit of polishing. How about the following: gitweb: fix generation of "gitweb.js" In 19d8fe7da65 (Makefile: extract script to generate gitweb.js, 2024-12-06) we have extracted the logic to build "gitweb.js" into a separate script. As part of that the rules that builds the script has gained a new dependency on that script. This refactoring is broken though because we use "$^" to determine the set of JavaScript files that need to be concatenated, and this implicit variable now also contains the build script itself. As a result, the build script ends up ni the generated "gitweb.js" file, which is wrong. Fix the issue by explicitly only passing the JavaScript files. > Signed-off-by: mirabilos We typically require plain names instead of aliases in the SOB. > --- > gitweb/Makefile | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/gitweb/Makefile b/gitweb/Makefile > index d5748e9359..2a8f97cef8 100644 > --- a/gitweb/Makefile > +++ b/gitweb/Makefile > @@ -118,7 +118,7 @@ $(MAK_DIR_GITWEB)gitweb.cgi: $(MAK_DIR_GITWEB)gitweb.perl > $(MAK_DIR_GITWEB)static/gitweb.js: $(MAK_DIR_GITWEB)generate-gitweb-js.sh > $(MAK_DIR_GITWEB)static/gitweb.js: $(addprefix $(MAK_DIR_GITWEB),$(GITWEB_JSLIB_FILES)) > $(QUIET_GEN)$(RM) $@ $@+ && \ > - $(MAK_DIR_GITWEB)generate-gitweb-js.sh $@+ $^ && \ > + $(MAK_DIR_GITWEB)generate-gitweb-js.sh $@+ $(addprefix $(MAK_DIR_GITWEB),$(GITWEB_JSLIB_FILES)) && \ > mv $@+ $@ We could avoid repetition by filtering out any files that we don't care about, like so: $(filter %.js,$^) In any case, thanks for discovering and fixing this issue!
