I have searched for similar MKDIR_P constructs in the lib/am files to know what is the current practice, but I haven't found any. I think it might be reasonable to use $(@D) fornow. In fact Automake is using it in its own Makefile (see "bin/Automake.inc"). Besides the portability issue, we need to figure out if this bug-fix doesn't bring some regressions (as suggested by the commit log sample of my previous email). I have run the test suite with the changes you have suggested, and the test suite doesn't complain except for the "XPASS" concerning the "t/lex-subobj-nodep.sh" test (the one I was refering too in my previous email). So this seems to look good, but this isn't enough to commit it confidently. I have discovered that this bug is a duplicate of #9859 for which you have already sent a patch 2 year ago. :) Thank you for investigating. -- Mathieu Lirzin GPG: F2A3 8D7E EB2B 6640 5761 070D 0ADE E100 9460 4D37

Hopefully there > should be a alternative. Can you look into it? $(dir ...) is most definitely not portable. One alternative is to use $(@D), which is specified in POSIX and essentially works in every make implementation that I know of. However, there are still portability gotchas. At least one implementation (dmake) supports $(@D) in principle but expands it in a not-quite-POSIX- compliant way. POSIX says that the expansion of $(@D) (and similar variables) does not include a trailing slash and expands to . for the current directory (i.e., when the target name does not contain a slash). In dmake, the expansion of $(@D) (and similar variables) for the current directory is the empty string, otherwise the expansion contains a trailing slash. In cases where the difference matters, this can be worked around in the shell easily enough. The difference matters if we adapt the above example because mkdir with an empty string will fail. Something like this should be pretty portable (untested): test x"$(@D)" = x || $(MKDIR_P) "$(@D)" Another way, perhaps even more portable, would be to do the splitting entirely in the shell, e.g., by using expr.

There is already an "expected fail" test case for the issue you have described. The commit 40c34328d1e5d3ab6885f046ce27517332413c13 which has intentionaly make the test fail has the following ChangeLog: +2011-10-20 Stefano Lattarini <stefano.lattarini@HIDDEN> + + deps: partially revert commit `v1.11-512-geeee551' + This change partly reverts commit "Create subdirs for generated + sources even when not dep tracking", of 2011-04-02. + That commit had caused the bugs #8485 and #8526. Since we are + nearing the bug-fixing automake release 1.11.2, the safest policy + at the moment is to just revert the problematic hunks: an older, + known bug is better than a regression. + * automake.in (handle_single_transform): Don't add a dirstamp + dependency, even when $object is derived and lands in a subdir. + * tests/Makefile.am (XFAIL_TESTS): Add lex-subobj-nodep.test, + remove yacc-dist-nobuild-subdir.test. This seems to imply that this has not been fixed because of time constraints before a release. Can you investigate more to see if your patch doesn't reintroduce problems from bugs #8485 and #8526? > > A simple patch to lex.am and yacc.am fixes this. > >>From bd6971224f304c8f5951afca620f33c25248b446 Mon Sep 17 00:00:00 2001 > From: Nicholas Brown <brownn@HIDDEN> > Date: Fri, 4 Dec 2015 10:49:18 +0000 > Subject: [PATCH] yacc and lex built objects without dependancy tracking > > --- > lib/am/lex.am | 1 + > lib/am/yacc.am | 1 + > 2 files changed, 2 insertions(+) > > diff --git a/lib/am/lex.am b/lib/am/lex.am > index d7ddc77..6357507 100644 > --- a/lib/am/lex.am > +++ b/lib/am/lex.am > @@ -23,6 +23,7 @@ endif %?MAINTAINER-MODE% > > ?GENERIC?%EXT%%DERIVED-EXT%: > ?!GENERIC?%OBJ%: %SOURCE% > +?SUBDIROBJ? %SILENT%test -d $(dir $@) || $(MKDIR_P) $(dir $@) I suspect the '$(dir ..)' syntax is not portable.
