From 3e073dc561185d5ad2325cb012943020e068801e Mon Sep 17 00:00:00 2001 From: =?utf8?q?Andreas=20F=C3=A4rber?= Date: Mon, 25 Aug 2008 17:33:03 +0200 Subject: [PATCH] Makefile: always provide a fallback when hardlinks fail MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We make hardlinks from "git" to "git-" built-ins and have been careful to avoid cross-device links when linking "git-" to gitexecdir. However, we were not prepared to deal with a build directory that is incapable of making hard links within itself. This patch corrects it. Instead of temporarily linking "git" to gitexecdir, directly link "git- add", falling back to "cp". Try hardlinking that as "git-", falling back to symlinks or "cp" on error. While at it, avoid 100+ error messages from hardlink failures when we are going to fall back to symlinks or "cp" by redirecting the standard error to /dev/null.
