If doing this, you must also build a specific 8 # library target such as 'libdeflate.a', as the programs will no longer compile. 9 # 10 # Define DISABLE_GZIP to disable support for the gzip wrapper format. 11 # 12 # Define DISABLE_ZLIB to disable support for the zlib wrapper format. 13 # 14 ############################################################################## 15 16 #### Common compiler flags. 17 #### Flags given here are not intended to be overridden, but you can add more 18 #### by defining CFLAGS in the environment or on the 'make' command line. 19 20 cc-option = $(shell if $(CC) $(1) -c -x c /dev/null -o /dev/null \ 21 1>&2 2>/dev/null; then echo $(1); fi) 22 23 override CFLAGS := \ 24 $(CFLAGS) -O2 -fomit-frame-pointer -std=c99 -I. -Icommon \ 25 -Wall -Wundef \ 26 $(call cc-option,-Wpedantic) \ 27 $(call cc-option,-Wdeclaration-after-statement) \ 28 $(call cc-option,-Wmissing-prototypes) \ 29 $(call cc-option,-Wstrict-prototypes) \ 30 $(call cc-option,-Wvla) 31 32 ############################################################################## 33 34 STATIC_LIB_SUFFIX := .a 35 SHARED_LIB_SUFFIX := .so 36 SHARED_LIB_CFLAGS := -fPIC 37 PROG_SUFFIX := 38 PROG_CFLAGS := 39 HARD_LINKS := 1 40 41 # Compiling for Windows with MinGW? 42 ifneq ($(findstring -mingw,$(shell $(CC) -dumpmachine 2>/dev/null)),) 43 STATIC_LIB_SUFFIX := .lib 44 SHARED_LIB_SUFFIX := .dll 45 SHARED_LIB_CFLAGS := 46 PROG_SUFFIX := .exe 47 PROG_CFLAGS := -static -municode 48 HARD_LINKS := 49 override CFLAGS := $(CFLAGS) $(call cc-option,-Wno-pedantic-ms-format) 50 51 # If AR was not already overridden, then derive it from $(CC). 52 # Note that CC may take different forms, e.g. "cc", "gcc", 53 # "x86_64-w64-mingw32-gcc", or "x86_64-w64-mingw32-gcc-6.3.1". 54 # On Windows it may also have a .exe extension. 55 ifeq ($(AR),ar) 56 AR := $(shell echo $(CC) | \ 57 sed -E 's/g?cc(-?[0-9]+(\.[0-9]+)*)?(\.exe)?$$/ar\3/') 58 endif 59 endif 60 61 ############################################################################## 62 63 #### Quiet make is enabled by default.
