Hello everyone,
the recent round of updates to the gnulib stuff triggered what must be a
rather old bug in the tp/maintain/regenerate_docstr.pl script. It
completely fails to work in out-of-tree, a.k.a. VPATH builds. The
problem is that this perl script writes makefile rules into
tp/Makefile.docstr which look like this:
$(srcdir)/../po_document/'"$lingua.gmo"':
$(srcdir)/../po_document/'"$lingua.po"'
cd $(srcdir)/../po_document/ && $(MAKE) $(AM_MAKEFLAGS) '"$lingua.gmo"'
But in a VPATH build, there is no makefile in $(srcdir)/../po_document.
The Makefile to be used is in $(builddir)/../po_document instead, or the
shorter version: ../po_document. So the above rule really should become
$(srcdir)/../po_document/'"$lingua.gmo"':
$(srcdir)/../po_document/'"$lingua.po"'
cd ../po_document/ && $(MAKE) $(AM_MAKEFLAGS) '"$lingua.gmo"'
Or maybe, since the comment above this line already claims that this
part is maintainer-only, and thus assumes GNU make:
$(srcdir)/../po_document/'"$lingua.gmo"':
$(srcdir)/../po_document/'"$lingua.po"'
$(MAKE) -C ../po_document $(AM_MAKEFLAGS) '"$lingua.gmo"'
Or maybe it should just run a single sub-make in po_document from tp's
$(builddir) and be done with that, instead of one sub-make per
out-of-date .po file target.
Cheers
