From 0265c80544aac93e238bcfb2d61afc547c48a829 Mon Sep 17 00:00:00 2001 From: "Matthias P. Braendli" Date: Wed, 7 Mar 2018 12:25:59 +0100 Subject: Remove --enable-debug configure flag With --enable-debug, compiler flags include -g -O2, i.e. with debugging, with optimisations. Without --enable-debug, compiler flags include -g -O2 -DNDEBUG -g -O2 are defaults according to AC_PROG_CXX The macro NDEBUG has a small performance impact (less than 1%), but can put issues to light. It is beneficial to have assertions always enabled. Remove the flag, and let the user override CFLAGS/CXXFLAGS if he wishes to.
