I really hate these second rate shells, but I guess we could do this on
the grounds of POSIX sh not specifying the brace expansion.

The other solution is to use standard-make features like in
mkdir -p $(foreach d,ui/browsers scripting-engines,$(OUTPUT)util/$(d)/) 2> /dev/null

Is there actually a specific reason for the 
$(shell sh -c '...')
around?
It looks superflous.

I think the reason is is that nobody who touched that file really knew
make all that well. Your version looks fine to me.

Ah, the reason is that they are not part of a rule but on the top-level
(and thus always executed).

So it worked by luck! /me runs :-P

More seriously, so there is a reason for that to be like that and you're
not aware of any other shorter or more convenient way of achieving that
goal, right?

IMHO it's not really luck with GNU-make.

One (obvious) alternative is to have rules triggering on the
non-existence of these directories.

> goal, right?

Hmm, I'm not a "perf person". Which are the sufficient use-cases/tests
that one can do to play around with the Makefile?

`make -C tools/perf` is probably not enough.

Any hints anyone?

Right, not enough, what those mkdir calls were added for was exactly for
a different usecase:

make -C tools/perf -O=~/build/perf/

So that it doesn't pollutes the source code directories with the object
files, behaving in a similar fashion as when using O= in the kernel
proper.

Thanks.

The following patch below at the end works for me. Alas, it is against
vanilla main line.
----  snip  ----
Replace the global $(shell ...) lines quite at the top creating the output
directories with real rules.

Adding $(OUTPUT)PERF-VERSION-FILE $(OUTPUT)common-cmds.h there, to have it look:

+# we compile into subdirectories. if the target directory is not the source directory, they might not exists. So
+# we depend the various files onto their directories.
+$(LIB_OBJS) $(BUILTIN_OBJS) $(OUTPUT)PERF-VERSION-FILE $(OUTPUT)common-cmds.h: $(sort $(dir $(LIB_OBJS) $(BUILTIN_OBJS)))
+# In the second step, we make a rule to actually create these directories
+$(sort $(dir $(LIB_OBJS) $(BUILTIN_OBJS))):
+       mkdir -p $@ 2>/dev/null
+

As it was failing when I did:

rm -rf ~/build/perf
make -C tools/perf O=~/build/perf

With that it retains the existing functionality,

Thanks,

Hmm, that adds that $(OUTPUT)PERF-VERSION-FILE and
$(OUTPUT)common-cmds.h (also) depends on the subdirectories of the other
objects (and thus it works always because at least one of them is a
subdirectory of $(OUTPUT)).
To be 110% anal, it should look like e.g.
+$(LIB_OBJS) $(BUILTIN_OBJS) $(OUTPUT)PERF-VERSION-FILE $(OUTPUT)common-cmds.h: $(sort $(dir $(LIB_OBJS) $(BUILTIN_OBJS)) $(OUTPUT))

or actually all targets.

BTW there is no automatic variable or other make-construct to refer in
the dependencies on the own target. Therefore the copy-paste-the-
variables solution.

Perhaps an additional variable reduces clutter (and eases maintenance)?

+# we compile into subdirectories. if the target directory is not the source directory, they might not exists. So
+# we depend the various files onto their directories.
+DIRECTORY_DEPS = $(LIB_OBJS) $(BUILTIN_OBJS) $(OUTPUT)PERF-VERSION-FILE $(OUTPUT)common-cmds.h
+$(DIRECTORY_DEPS): $(sort $(dir $(DIRECTORY_DEPS)))
+# In the second step, we make a rule to actually create these directories
+$(sort $(dir $(DIRECTORY_DEPS))):
+       mkdir -p $@ 2>/dev/null
+

That should guarantee that all directories from the targets are created.

Ah, I `mkdir`ed the output directory explicitly before the `make` (and
after the `rm -rf`).


BTW which is the preferred tree to base patches on (for the "perf"
subsystem)?

git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip

perf/urgent for 2.6.36
perf/core for 2.6.37

I'm targeting perf/urgent for this fix.

Or git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux-2.6

Sometimes, when Ingo is busy and patches accumulate, perf/{core,urgent}
are where I put things to go to the branches with the same names on his
tree.

Please look if patch is OK with you.
