C语言项目设计——GCC构建项目

（1）构建算法库（静态/动态）

（2）构建库测试执行体

由此，设计两个markfile文件，sub.mk用以构建算法库，Makefile用以构建执行体。

项目的目录设计参考如下

----build(存放编译工具)

----include(库头文件)

----src（代码文件夹）

--------app(执行体代码)

--------core(库代码)

--------sub.mk

----Makefile

----libxxx.so

----xxx.exe

Makefile

TARGET = xxx
CC = gcc.exe
AR = ar.exe

BUILD_TIME = $(shell date "+%Y-%m-%d-%H-%M-%S.%N" | cut -b 1-23)
BUILD_BRANCH = $(shell git branch | grep * | cut -d ' ' -f2)
BUILD_LATEST_COMMIT = $(shell git log --oneline -1 | cut -d ' ' -f1)
CFLAGS = -DBUILD_ENV=""$(HOST_TAG)"" -DBUILD_TIME=""$(BUILD_TIME)"" -DBUILD_BRANCH=""$(BUILD_BRANCH)"" -DBUILD_LATEST_COMMIT=""$(BUILD_LATEST_COMMIT)""

CFLAGS += -DMULTI_THREAD_SUPPORT
CFLAGS += -DDEBUG_TIME # print running time

#CFLAGS += -g -fstack-protector-strong -fsanitize=address -fsanitize=leak -fsanitize=undefined -fno-omit-frame-pointer
#LDLIBS += -fsanitize=address

	del $(subst /,,$(OBJ)) $(TARGET).exe

sub.mk

TARGET = libxxx
LIB = libxxx.a
XXX_DLL = libxxx.so
XXX_DIR = lib
XXX_SRC = $(wildcard src/core/*.c src/utility/*.c src/neon/*.c)

XXX_OBJ = $(patsubst %.c, %.o, $(XXX_SRC))

LIB_PATH += -L ./$(XXX_DIR)
LIBS += -l:$(XXX_LIB)

# generate static library
xxxlib:$(XXX_OBJ)
	$(AR) cq $(XXX_DIR)/$(XXX_LIB) $^

# generate shared library
xxxdll:$(XXX_OBJ)
	$(CC) -fPIC -shared -o $(XXX_DIR)/$(XXX_DLL) $^

.PHONY: libclr
libclr:
	del $(XXX_DIR)$(XXX_DLL)
	del $(XXX_DIR)$(XXX_LIB)
ifneq (,$(subst /,,$(XXX_OBJ)))
	del $(subst /,,$(XXX_OBJ))
endif

在windows平台上编写bat脚本，方便快速执行构建命令，同理，在Linux平台可以编写sh脚本。

set PATH=%cd%buildwindowsbin;%cd%buildwindowslibexecgccx86_64-w64-mingw328.1.0;
set LIBRARY_PATH=%cd%buildwindows_64x86_64-w64-mingw32lib;
set LD_RUN_PATH=%cd%buildwindows_64x86_64-w64-mingw32lib;
set C_INCLUDE_PATH=%cd%buildwindowsinclude;%cd%buildwindowslibgccx86_64-w64-mingw328.1.0include;
%cd%buildwindowsbinmingw32-make.exe cleanall
%cd%buildwindowsbinmingw32-make.exe all
pause

set BUILDPATH=%cd%buildwindowsbin;%cd%buildwindowslibexecgccmingw32\9.2.0;
set PATH=%BUILDPATH%
PATH
%cd%buildwindowsbinmingw32-make.exe cleanall
