make distclean

Hi,

I have received a bug-report saying that 'make distclean' fails for GNU APL.

The error message is this:

make[2]: Entering directory `/home/eedjsa/projects/juergen/apl-1.5/src'

----------------------------------------------------------------------------------------------------

From what I can see:

(1) the libapl related files should not be deleted in the first place .
The Makefile.am (attached) uses:

if WANT_LIBAPL

which is an AM_CONDITIONAL() and the project was NOT ./configure'd to
build libapl

(2) why would 'make distclean' try (and then fail) to build any targets
in the first place?

Shouldn't it just delete files created by ./configure and be happy if
they are gone?

------------------------------------------------------
automake version is 1.14.1
autoconf version is 2.69

The whole project is at http://svn.savannah.gnu.org/viewvc/trunk/?root=apl

Sometimes make distclean works, but I haven't figured when.

Thanks,

Hard to tell what's going on here without seeing the message from 'make
distclean' before the error message.

Well, 'make distclean' always deletes directory '.deps' if their's
compilation going on.

It's not trying to build anything. It's trying to remove deps files,
which are created by configure (and usually updated by the compiler).

Hi Peter,

thanks for looking into this.

Attached is the full log (shortest way to reproduce the problem.
I could have run 'make all' as well bu the result would be the same.

What puzzles me the most is the message:

make[2]: *** No rule to make target `.deps/libapl_la-libapl.Plo'. Stop.

because why would 'make distclean' even try to make that target?

Thanks,
JÃŒrgen

Hi Mike,

I am not using the subdir-objects option. Should I ?

Also, if I

./configure
make distcleran

then the compiler will not yet have been run.
But your explanation have given me an idea: if I remove the .deps directory
manually then 'make distclean' seems to work again.

Not very nice but at least work-around.

Thanks,
Jürgen

Thanks for the full log, that gives enough information to explain this.
Makefiles include all of the files in .deps (as a make include). Make
treates included files as prerequisites of the makefile itself, so they
need to exist in order for any target to run, including any *clean
targets.
Turns out from your log file that a subdirectory of src is removing the

This is probably why when 'distclean' returns to src, its .deps files
are already removed and the makefile errors out.
Are sources from the parent directory being built in the src/APs subdir
and you're using the 'subdir-objects' option?
