[Message part 1 (text/plain, inline)]

When subdir-objects option is enabled (without subdir-objects all works
fine) and xxx_SOURCES contains paths stored in variables when automake
tries to create directory named by variable name not value. For example:

FOO=/path/to/foo
foo_SOURCES=$(FOO)/bar.cpp

Automake tries create directory $(FOO) not /path/to/foo, and make can not
find dependencies.
I attached minimal example. It use non recursive make, but recursive make
also fails.

In attached project problem seems to be in line 310 in generated
Makefile.in. If I replace $(XXXDIR) with xxx manually, then all works fine.

I use autoconf 2.69, automake 1.12.1 and gmake 3.82.

I believe this is another issue caused by the limitations that are at the
root of http://debbugs.gnu.org/13928 as well.  This is a well-known issue,
and we should aim at fixing it before Automake 2.0 is released.

Known bugs sadly -- all duplicates of http://debbugs.gnu.org/13928

See also recent thread on the automake list (with sad updates
regarding the current Automake development status):
http://lists.gnu.org/archive/html/automake/2014-04/msg00002.html

Closing these bug as a duplicate.  Feel free to continue the
discussion in the http://debbugs.gnu.org/13928 thread.  And
if anyone manages to come up with a patch, I will certainly
make time to review it.

Thanks, and sorry for the lack of progress,
  Stefano
