CMakeLists編寫

cmake生成makefile

cmake_minimum_required(VERSION 3.12.3)
# Project name
PROJECT(test_main)
# Head file path
INCLUDE_DIRECTORIES(
	include
)
# Source directory: src/
AUX_SOURCE_DIRECTORY(src DIR_SRCS)
# Set environment variable
SET(TEST_MAIN
	${DIR_SRCS}
)

# Set output binary path: bin/
SET(EXECUTABLE_OUTPUT_PATH ${PROJECT_BINARY_DIR}/bin)

#LINK_DIRECTORIES(../bin)

# Add executable file: /bin/test_out，文件名不帶路徑
ADD_EXECUTABLE(main_out ${TEST_MAIN})

# Add link library: math library
#TARGET_LINK_LIBRARIES(../bin/${PROJECT_NAME} libm.so)


# 生成動態庫目標
add_library(test_main SHARED ${DIR_SRCS})
# 生成靜態庫目標, 不能重名
add_library(test_main_static STATIC ${DIR_SRCS})

# 指定靜態庫的輸出名稱
set_target_properties(test_main_static PROPERTIES OUTPUT_NAME "test_main")
# 使動態庫和靜態庫同時存在，同名
set_target_properties(test_main PROPERTIES CLEAN_DIRECT_OUTPUT 1)
set_target_properties(test_main_static PROPERTIES CLEAN_DIRECT_OUTPUT 1)

# 指定動態庫版本
# VERSION 動態庫版本
# SOVERSION API版本
# set_target_properties(test_main PROPERTIES VERSION 1.0 SOVERSION 1)

手寫Makefile

	gcc -o main $^
dep_files := $(foreach f,$(objs),.$(f).d)

ifneq ($(dep_files),)
	include $(dep_files)
endif

%.o : %.c 
	gcc -Wp,-MD,[email protected] -c -o $@ $<
	
clean:
	rm *.o main
