shell脚本自动生成makefile

效果展示

生成的makefile是这样的效果：

# automake version 1.0
CC  = gcc
BIN = pkg
OBJ = pkg.o
LIB = 
INC = 
FLAGS = $(INC) -Wall

pkg: pkg.o
	$(CC) $(OBJ) -o $(BIN) $(LIB)
pkg.o: pkg.c err.h color.h
	$(CC) -c pkg.c -o pkg.o $(FLAGS)

.PHONY: clean
clean:
	rm $(OBJ) $(BIN)

使用示例

会自动处理依赖关系（额外库库和头文件路径要手动添加）。
额外库(LIB)和头文件路径(INC)会留空，不需要请手动移除对应代码。

$automake
Usage: automake <target.c>

<target.c>是你的main()函数所在文件，生成的可执行程序名为main()所在.c文件的文件名去掉后缀名。

源代码

#!/bin/bash

RED="\033[0;31m"
GREEN="\033[0;32m"
NONE="\033[0m"

if	[ $# != 1 ]
then
	printf "${RED}Usage: automake <target.c>\n${NONE}"
	exit 0
fi
