From 26f215d13756b0356c2aaa6d6bfc71ae99d6c1e5 Mon Sep 17 00:00:00 2001 From: Andrew Parlane Date: Wed, 18 Mar 2015 15:10:29 +0000 Subject: [PATCH] target-finalize: Use NULL deliminators when stripping the target directory. Special characters in files or directories in the rootfs can cause problems when stripping files. For example "target/some song.mp3" gets treated as two entries. "target/some" and "song.mp3" are both passed to $(STRIPCMD). This then errors saying files don't exist. Additionally a ' and possibly other special characters in a file path causes xargs to give the error: "xargs: unmatched single quote; by default quotes are special to xargs unless you use the -0 option". This also has the effect of removing this entry and further entries from the list of files to strip. This can be demonstrated by having a test directory with the files: "cat" "rabbit's" "elephant". then running the command: "find -name "*" -print | xargs" To fix this we pass -print0 to find which seperates entries with a NULL character, and we pass -0 to xargs to tell it to only use NULL characters as the deliminator.
