From 04f80ac2c822543f130c30942560e4a3300f8481 Mon Sep 17 00:00:00 2001 From: lingsheng Date: Tue, 28 Jul 2020 09:41:05 +0800 Subject: [PATCH] Don't redefine gettid if glibc provides it glibc 2.30+ include a definition for gettid() so that users don't have to manually define gettid() with syscall(). Old code don't check this, this will redefine gettid() on the latest versions of glibc, causing build fail.
