How to execute commands in case of interruption of makefile execution

[w***@yahoo.com.br]

Hello,

I'd like to execute some cleanup commands in case of interruption
(CTRL-C or something) of the normal makefile execution. These commands
do more than simply delete intermediary files, so .INTERMEDIATE rule
does not solve my problem. A way to execute commands upon termination
of the Makefile, regardless the termination is forced or not (something
like the Perl END routine) would help too.

Is there any way to achieve what I need?

Thanks in advance.

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 ...

Cheers,

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

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.

You can still do it with a sub-make.

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

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

Bye.
