tpm2-tools中Makefile的关键宏定义

AM_V_CC

AM_V_CC = $(am__v_CC_$(V))

可以看到，AM_V_CC实际上分为两个部分：am__v_CC_和V。

am__v_CC_相关定义如下：

am__v_CC_ = $(am__v_CC_$(AM_DEFAULT_VERBOSITY))

AM_DEFAULT_VERBOSITY = 0

am__v_CC_0 = @echo "  CC      " $@;

变量V并没有被赋值，为空。

因此，综上得到AM_V_CC的值实际为：

@echo " CC " $@;

CC = gcc

DEFS

DEFS = -DHAVE_CONFIG_H

DEFAULT_INCLUDES

DEFAULT_INCLUDES = -I. -I$(top_builddir)/lib

top_builddir = .

综上，最终得到AM_V_CC的值实际为：

-I. -I./lib

INCLUDES

变量INCLUDES并没有被赋值，为空。

AM_CPPFLAGS

变量AM_CPPFLAGS并没有被赋值，为空。

CPPFLAGS

CPPFLAGS =  -D_FORTIFY_SOURCE=2

tools_tpm2_CFLAGS

tools_tpm2_CFLAGS = $(AM_CFLAGS) -DTPM2_TOOLS_MAX="$(words $(tpm2_tools))"

AM_CFLAGS := \
    $(INCLUDE_DIRS) $(EXTRA_CFLAGS) $(TSS2_ESYS_CFLAGS) $(TSS2_MU_CFLAGS) \
    $(CRYPTO_CFLAGS) $(CODE_COVERAGE_CFLAGS) $(TSS2_TCTILDR_CFLAGS) \
    $(TSS2_RC_CFLAGS) $(TSS2_SYS_CFLAGS)

这个涉及的项就比较多了，直接给出最终的值为：

-I./tools -I./lib -Wall -Wextra -Wformat -Wformat-security -Wstack-protector -fstack-protector-all -Wstrict-overflow=5 -O2 -fPIC -fPIE -D_GNU_SOURCE -std=gnu99 -Wstringop-overflow=4 -Wstringop-truncation -Wduplicated-

CFLAGS

变量CFLAGS并没有被赋值，为空。
