Subject: distcheck fails to detect missing files

Hi,

I have this snippet in my 'Makefile.am'


include am/test_data.am

$(srcdir)/am/test_data.am: $(srcdir)/test/data.txt 
$(srcdir)/am/test_data.am.in
    cd $(srcdir) && $(SHELL) bootstrap am/test_data.am


It first includes (at Automake time) a snippet, which is generated while 
bootstrapping. Now I forgot to include $(srcdir)/test/data.txt 
$(srcdir)/am/test_data.am.in in the distball, which caused the embarrassing

make: *** No rule to make target `am/test_data.am.in', needed by 
`am/test_data.am'.  Stop.

The surprising thing is that distcheck does not detect this problem, but 
'make distcheck' passes through without problem. The reason for this is 
probably because while $(srcdir)/test/data.txt does not exist, make also 
looks in $(srcdir)/$(srcdir)/test/data.txt and that file exists as it is 
part of my development directory. If I change my Makefile.am to

$(srcdir)/am/test_data.am: test/data.txt am/test_data.am.in
    cd $(srcdir) && $(SHELL) bootstrap am/test_data.am


'make distcheck' will detect the problem, but I have this habit of type 
$(srcdir) for things that are supposed to be in $(srcdir). Is that a bad 
habit?

A fix could be to let distcheck not work in $(distdir) but instead 
create 'tmp_/$(distdir)', builddir 'tmp_/$(distdir)/$(builddir)', and 
installdir 'tmp_/$(distdir)/inst_' which would hide the development 
files from the distcheck. What do you think?

Thanks,
Peter
