Hi,
yeah, well, Makefiles, … in T2 we use wrappers for compilers et al. to inject
everywhere deterministically the compiler flags we want, …
While at it I wanted to make my life easier and base CXXFLAGS on CFLAGS. For
some magic that did not work with
CXXFLAGS ?= $(CFLAGS) …
so I ended up committing this for now:
--- Makefile (revision 2056)
+++ Makefile (revision 2057)
@@ -7,10 +7,8 @@
X_BUILD_IMPLICIT=1
# -s silcently corrupts binaries on OS X, sigh -ReneR
-CFLAGS = -Wall -O2
-CXXFLAGS = -Wall -O2 -Wno-sign-compare
-#CFLAGS = -Wall -O0 -ggdb
-#CXXFLAGS = -Wall -O0 -ggdb
+CFLAGS ?= -Wall -O2 # -O1 -ggdb # -fsanitize=address -fsanitize=undefined
+CXXFLAGS = $(CFLAGS) -Wno-sign-compare
# for config.h
CPPFLAGS += -I .
I hope it works for you.
I will review the other patches a bit later when I have more time.
René
