From 36feb98e568221e24286615730888d5f6ff323f0 Mon Sep 17 00:00:00 2001 From: Hongxu Jia Date: Fri, 7 Dec 2018 15:12:38 +0800 Subject: [PATCH] introduce a special build flag to explicitly disables running from build tree It is helpful to improve reproducibility build [1] since PA_SRCDIR/PA_BUILDDIR contains build path, disable running from build tree could drop these macros at precompilation.
