From 7a5fb319e557a94b64785d4312ceda197e317248 Mon Sep 17 00:00:00 2001 From: Jim Meyering Date: Thu, 18 Feb 2016 09:19:44 -0800 Subject: [PATCH] do not emit rule with two .deps/alloca.Po dependents On a system using our replacement alloca, make would emit this warning: target '.deps/alloca.Po' given more than once in the same rule That arose because automake would emit a rule depending on both ./.deps/alloca.Po and .deps/alloca.Po. Normally, duplicate dependents are avoided by virtue of their names being keys in the %dep_files hash, but in this case, that particular file was specified in two different ways. * bin/automake.in (handle_ALLOCA): When the $dir prefix is empty, make it './', to ensure that when we add ./.deps/alloca.Po it is deduped. --- bin/automake.in | 1 + 1 file changed, 1 insertion(+) diff --git a/bin/automake.in b/bin/automake.in index c1d1a8a..7508bc2 100644 --- a/bin/automake.in +++ b/bin/automake.in @@ -2208,6 +2208,7 @@ sub handle_ALLOCA $lt ||= ''; my $dir = handle_LIBOBJS_or_ALLOCA "${lt}ALLOCA"; + $dir eq '' and $dir = './'; $var->requires_variables ("address@hidden@ used", $lt .
