From 7701fc53d19be7cab8bddba72046a39e8421fd9e Mon Sep 17 00:00:00 2001 From: Thomas De Schampheleire Date: Sat, 21 Jun 2014 17:01:47 +0200 Subject: [PATCH] infra: support buildroot being located in /usr pkg-generic and pkg-autotools both perform sed replacements of /usr to $(STAGING_DIR)/usr, in .pc and .la files respectively. However, if buildroot itself is located in /usr, then STAGING_DIR also starts with /usr, and naive replacements of '/usr' can result in paths of the form: /usr/buildroot/.../sysroot/usr/buildroot/.../sysroot/... This patch makes the replacements more careful, by first replacing the known paths BASE_DIR and STAGING_DIR to tokens, then performing the actual replacement, and finally replacing the tokens with the corresponding paths. Additionally it removes the unnecessary making of a backup copy in pkg-autotools.
