From 6caa76db22ad952f3fe6329da39defed060d8980 Mon Sep 17 00:00:00 2001 From: Danomi Manchego Date: Tue, 22 Nov 2016 21:31:31 -0500 Subject: [PATCH] Makefile: drop redundant shell call when deriving BASE_DIR Commit 173135df5b69dfd5ae6fe6cf2de8833c6f74c143 ("core: re-enter make if $(CURDIR) or $(O) are not canonical paths") introduced the CANONICAL_O variable, defined as: CANONICAL_O := $(shell mkdir -p $(O) >/dev/null 2>&1)$(realpath $(O)) This duplicates the definition of BASE_DIR, by different means: BASE_DIR := $(shell mkdir -p $(O) && cd $(O) >/dev/null && pwd) So one of these shell calls is redundant. CANONICAL_O is defined first, so this commit replaces the BASE_DIR derivation with $(CANONICAL_O).
