Hi,
I see quite a few Vala projects setting VALAFLAGS as follows:
libfolks_eds_la_VALAFLAGS = \
--vapidir=. \
--vapidir=$(top_srcdir)/folks \
...
This is referred by the generated rule in Makefile.in as:
$(AM_V_VALAC)$(am__cd) $(srcdir) && $(VALAC) $(libfolks_eds_la_VALAFLAGS)
$(VALAFLAGS) -C $(libfolks_eds_la_SOURCES)
Here, if $(srcdir) != $(builddir) and $(top_srcdir) is a relative path
from $(builddir), the --vapidir option will point to a wrong location.
Though this could be worked around by using $(abs_top_srcdir) instead of
$(top_srcdir), it looks to me a bit unintuitive. It would be nice that
automake handles this case nicely.
