Makefile and standard includes

Mornin' All

I'm sure this is dead easy but I can't figure it out. I use MarkDown to convert content text to html but MarkDown does not provide the appropriate "<html><head>...</head><body>" and "</body></html>" tags. A perfect automation job for make, thinks I.

Here's the make file I have at the moment. It works fine to build the final html file in general. The problem is that it doesn't trigger a rebuild when I change html_header.inc or html_footer.inc.

Any clues?

MYINC=$(HOME)\etc
VPATH=.:$(MYINC)

%.html : %.inc
cat "$(MYINC)/html_header.inc" >> $@
cat $< >> $@
cat "$(MYINC)/html_footer.inc" >> $@

%.inc : %.txt
/usr/local/bin/markdown.pl $< > $@

Thanks in advance.

- %.html : %.inc
+ %.html : %.inc $(MYINC)/html_header.inc $(MYINC)/html_footer.inc
will not work?

I figured that for the solution as well but, no, it doesn't work. make throws up this error:

"mixed implicit and static pattern rules. Stop.'"

My understanding is that implicit rules (whether built-in or user defined) must be of the format "%.html : %.inc" with no other dependencies listed. This is despite http://gnu.huihoo.org/make-3.77/html_chapter/make_10.html which says:

"%.o: %.c foo.h
$(CC) -c $(CFLAGS) $(CPPFLAGS) -o $@ $<

which tells how to make `.o' files from `.c' files, and makes all `.o' files using this pattern rule also depend on `foo.h'. "

What are your targets? Can you please post the entire Makefile (if very long, post as file e.g. Makefile.txt)
The problem with that line may be that the same file can match both kinds of patterns.
I tried guessing a target but can't reproduce the error you see

That is the entire makefile. That what puzzles me. I call it as

% make filename.html

and expect that it looks for filename.txt, checks whether it's newer then filename.html (if it exists) and builds as required.
Makefile.txt

what OS and make You use - it works perfectly at my side, try also (dependencies should summarize)

*.html : $(MYINC)/html_header.inc $(MYINC)/html_footer.inc
%.html : %.inc
...

Holy cow! I've been looking at this for a week and have only seen this after it was pointed out. That's what you get for working in a mixed linux/Windows environment. Thank you very much. Works perfectly now.

So that's it? Correcting the typo fixed Your problem?

You can't imagine what an idiot I feel or how much time I've sunk into this but, yes, correcting the typo fixed it. I've been in this game a long time and to be stumped by something this dumb is ... is .... well, I find it hard to believe. I really don't know how to apologise for wasting your time on something I should have been able to see at first glance.
