I have a makefile that looks something like this:
DIRS: x y z
If one of the nested makes fails I want this outer make to abort. I have
tried all kinds of gimicks but can’t seem to find the magic.
What is the trick to make this outer make abort if an inner make fails?
There may be better ways to do it but what I might try doing is checking the
return value of make within your script. If make fails, you just exit the
loop. The other option which you’ll find fairly educational is to look at
our recursive makefile stuff. Take a look at /usr/include/recurse.mk to see
how it’s done. The O’Reilly Make book is really good too.

My makefile is fashioned after the PhAB makefiles.
The “for; do ; done” below is a shell script line I know. But it is in a

I didn’t test this but something like this might do the trick. It seems to
me that make must invoke a shell to execute the commands under ‘all:’ so if
you caused that shell to exit with an error code, it should cause the make
to abort.

You should probably invoke make as $(MAKE) too, so that “make -n” will work.

Hi Kris
Thanks for all of your help. You’ve gone way above and beyond with all your
help both here and through e-mail.
The QNX4 make lacks a few features that the RTP make has that made most of
the suggestions unusable. They did however all give me good ideas.
DIRS := $(shell ls -D)
firstdir := $(firstword $(DIRS))
restdir := $(filter-out $(firstdir), $(DIRS))
ifneq ($(findstring k,$(MFLAGS)),)
sep := ;
else

endif
…PHONY: all
all:
cd $(firstdir) && $(MAKE) --no-print-directory $(MAKEFLAGS)
$(foreach dir, $(restdir), $(sep)
cd …/$(dir) && $(MAKE) --no-print-directory $(MAKEFLAGS) )

Well, thank you. But I like to think I didn’t start at zero. I had written
some pretty fancy makefiles in my time. I’ve posted some of them. I like
to write makefiles that don’t need to be updated ever as new modules are
added to a project.
So now I have four kinds of makefiles.

Ah! But my working bin and lib directories are not within the normal
directory structure. They are stored on a Hugh RAM disk for speed. An
‘install’ goal copies the files to hard drive directories.

So what, just create dummy directory or even file to let the make
know what type to build of target to build. Where the target goes is
irrelevent.
Personnaly I’ve inspired myself from QNX common makefiles.
Creating directory x86/o will generate an executable.
Creating directory x86/a will generate a library
Creating directory x86/so will generate a share object
Creating directory x86/o.d will generate a debugged executable
…
For know I don’t support anything else then x86 cause that’s all I need
I one project I added support for qnx4/o, qnx4/a, … The same makefile
and source can be use for both QNX6 and QNX4.
