Recursive make and the default target

[jontra]

Hi,

I am currently working on converting our old gnu make makefiles into makepp.

One of the problems I am facing is the way makepp calculate the default target.

We now use recursive gmake, and in each sub dir 'all' target is recalculated, and actions are performed accordingly.

In makepp I don't use recursive make but use load_makefile to load the makefiles from the sub dirs (as needed).

If I understood correctly, when using makepp I will have to specify the final linking targets (and any other targets I want) in the top makefile.

for example:

makefile1.mk

$(phony all): bar

load_makefile t/makefile2.mk

bar:

    touch bar

makefile2.mk

$(phony all): foo

foo:

    touch foo

If I run makepp -f makefile1.mk only bat will be created and not foo.

I don't want to specify all the targets in the top level makefile since:

- I don't know in the top makefile all the targets from the sub dirs.
- one could run makepp from a sub dir, and i want to make all default targets from that subdir and all the sub dirs below it.

I hope i explained myself clearly.

Is there any way to solve this problem?

Thanks in advance,

Yoni.

Hi 
I used a global variable to solve this issue. 
I defined it with $make::some_var and updated it in each makefile.

    $(phony all): $((perl $make::some_var ))

Hope it will help anyone.

Hi Yoni,

sorry for the late reply!  You could just have said in your top level:

$(phony all): */**/all

i.e. the all`s in all subdirs recursively.

best regards

Hi Daniel, 
Thanks for the answer. 
I tried to use your approach, but it seem to work only on non phony rules. 
For example: 

Makefile1:

    load_makefile subdir/Makefile
    $(phony all): */**/all

Makefile2: 

    some_target:
    touch $(target)
   
    $(phony all): some_target
   
Give the Following result: 
makepp: Loading makefile \`/home/yoni/test/Makefile' 
makepp: Loading makefile \`/home/yoni/test/2/Makefile' 
makepp: 0 files updated and 1 phony target built 

But if i change all target (in Makefile2) to be non phony one: 

    all: some_target
            touch $(target)

Then it works file. 
I believe this is a small bug fix in makepp and hope you will find the time to fix it. 
Best regards, 
Yoni.

Sorry, that was off the top of my head, it should have been:

    $(phony all): $(only_phony_targets */**/all)
