I don't know if it's possible with make (or gnu make) I've never seen
such a thing.


With bash, you can use trap. So you could run your protected commands
from bash:

target:dependencies
bash -c "trap 'clean-up' INT TERM ; do-something"

or just invoke an external script:

target:dependencies
bin/do-something-and-clean-up



In general, in makefiles you just put a clean target to do the
cleaning up of any intermediate files that may remain from previous
makes.

May I suggest doing this with shell commands, in a wrapper or nested
make?
make || do_on_failure
do_always

Unfortunately I can't add the wrapper, the Makefile is called from a
monolithic application.

Thanks anyway.

This will execute do_on_failure on *any* failure;
the OP wanted to execute cleanup only on interruption.

It may or may not make sense to cleanup on other failures (perhaps
further investigation of why make failed in non-interrupted case
requires intermediate results).

You sure can:

all:
bash -c "trap 'clean-up' INT TERM ; $(MAKE) $(MFLAGS) target_with_cleanup"

target_with_cleanup: dependencies
whatever ...

You can still do it with a sub-make.

--- Makefile ---
all:
make -f sub.mk || on_failure
do_always

Seemed ambiguous to me (^C "or other"?)

sure you can... have the makefile run a bash script
and the bash script trap aborts and run the real makefile.

Bye.

By "other" I meant abnormal ends caused by interrupt signal sent by
kill, lack of resources, problems on the underlying file system, etc...

Yes, it is a clever solution. I'll try to explore this one.
