digitalmars.D.learn - Simple makefile problem - implicit rule

Anyone cares to explain what's wrong/missing?

Your post has spaces at the beginning on that line. (Thunderbird removes 
those when I reply. Curse!)

Target rules must start with a tab character.

Yeah, that's not the problem. Replacing %.obj and %.d with 
main.obj and main.d works.

And $< with main.d

  don't know what make you're using, but this works for me:

OBJS    = hello.obj hello_loop.obj
DC      = gdc
DCFLAGS =

all : $(OBJS)

%.obj : %.d
	$(DC) $< $(DCFLAGS) -o $ 

Output:
gdc hello.d  -o hello.obj
gdc hello_loop.d  -o hello_loop.obj

and hello.obj and hello_loop.obj both exist

Note that there is a tab before $(DC).

I'am using the make.exe coming with the DMD 2.061 distro in 
D/dmd2/windows/bin/
Thought/hoped the GNU spec was applicable, but if it works with 
GNU make and not Digital Mars make, well..

make -man leads to http://digitalmars.com/ctg/make.html, which 
says:

Does this give a clue?

Assuming that this is for GNU make, ensuring that the rule starts with a 
tab characters, that file works with GNU Make 3.81.

It is Digital Mars Make Version 5.06 and it's on Windows 7.

That's why you didn't mark the subject with [OT]. ;) It looks like the 
syntax is different:

.d.obj:
    $(DC) $(DFLAGS) -c $<

I got that by clicking "makefile example" here:

Works like a charm! Case solved.
Thank you very much!

from http://digitalmars.com/ctg/make.html:

Implicit Definition lines


Isn't targ_ext .obj and dep_ext .d?
If so, either the example or the documentation seems incorrect.

The example provided works. The .obj is updated when .d is 
modified.
Using
.obj.d:
     dmd $*.d -c

or

.obj.d:
     dmd $< -c

don't work.

My conclusion is that the documentation at 
http://digitalmars.com/ctg/make.html is incorrect. It should be:
