From 11e8c900ff085f3f9aad462f0369be5f801e1668 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Fri, 23 Nov 2018 15:58:06 +0100 Subject: [PATCH] Makefile: evaluate CCACHE and HOST{CC, CXX} at time of use As we are going to move to per-package SDK, the location of CCACHE and therefore the definitions of HOSTCC and HOSTCXX need to be evaluated at the time of use and not at the time of assignment. Indeed, the value of HOST_DIR changes from one package to the other. Therefore, we need to change from := to =. In addition, while doing A := $(something) $(A) is possible, doing A = $(something) $(A) is not legal. So, instead of defining HOSTCC in terms of the current HOSTCC variable, we re-use HOSTCC_NOCCACHE instead. Signed-off-by: Thomas Petazzoni Acked-by: "Yann E.
