生成简单的Makefile文件(Python实现)

在linux下写几个测试程序，还要一行行的输入g++命令进行编译，当经常改测试代码的时候，那一次次的敲（或者一次次的上线箭头选）也感觉不爽，不如make来的快。用Makefile的好处就不用多说了，这里我写了个脚本，其功能是自动搜索当前目录（不包括子目录）下的“.c”文件生成Makefile文件。
代码在这里，功能有限（适用于单个文件是一个独立的测试代码的情况），需要的朋友可以稍作修改以满足需求。

7 import os

9 def genMakefileStr(dir,surfix = '.c'):
10     msg = ''
11     msg = msg + 'CC = gcc' + '\n'
12     msg = msg +  'CFLAGS = -g -O2 -Wall' + '\n\n'
13
14     fList = []
15     for dirPath,dirNames,fileNames in os.walk(dir):
16         for file in fileNames:
17             name,extension = os.path.splitext(file)
18             if extension == surfix:
19                 fList.append(name)
20         break # only search the current directory
21     str1 = 'all:\n'
22     str2 = ''
23     str3 = 'clean:\n'
24     for f in fList:
25         str1 = str1 + '\tmake ' + f + '\n'
26         str2 = ('%s%s:%s.o\n') % (str2,f,f)
27         str2 = ('%s\t$(CC) -o %s %s.o\n\n') % (str2,f,f)
28         str3 = ('%s\trm -f %s\n') % (str3,f)
29     str3 = str3 + '\trm -f *.o\n'
30     strClean = '.c.o:\n\t$(CC) $(CFLAGS) -c -o $*.o $<\n'
31     msg = ('%s%s\n%s\n%s\n%s') % (msg,str1,str2,str3,strClean)
32     #print 'msg : \n'
33     #print msg
34     return msg
35
36 if __name__ == '__main__':
37     str = genMakefileStr('.','.c')
38     file = open("Makefile","w")
39     file.write(str)
40     file.close()
41     print str

运行效果如下（示例）：

1 # ./genMakefile.py
2 CC = gcc
3 CFLAGS = -g -O2 -Wall
4
5 all:
6         make pfun1
7         make pfun2
8
9 pfun1:pfun1.o
10         $(CC) -o pfun1 pfun1.o
11
12 pfun2:pfun2.o
13         $(CC) -o pfun2 pfun2.o
14
15
16 clean:
17         rm -f pfun1
18         rm -f pfun2
19         rm -f *.o
20
21 .c.o:
22         $(CC) $(CFLAGS) -c -o $*.o $<

运行脚本后进行make即可。

附：

感觉上面的那个脚本用着不方便，随后修改修改，代码如下：

#! /usr/bin/python
''' File : genMakefile.py Author : Mike E-Mail : Mike_Zhang@live.com '''
import os,sys surfix = ['.c','.cpp'] def genMakefileStr(dir): msg = '' msg = msg + 'CC = g++ ' + '\n' msg = msg +  'CFLAGS = -g -O2 -Wall' + '\n\n' fList = [] for dirPath,dirNames,fileNames in os.walk(dir): for file in fileNames: name,extension = os.path.splitext(file) if surfix.count(extension) > 0: fList.append(name) break # only search the current directory
str1 = 'all:\n' str2 = '' str3 = 'clean:\n'
for f in fList: str1 = str1 + '\tmake ' + f + '\n' str2 = ('%s%s:%s.o\n') % (str2,f,f) str2 = ('%s\t$(CC) -o %s %s.o\n\n') % (str2,f,f) str3 = ('%s\trm -f %s\n') % (str3,f) str3 = str3 + '\trm -f *.o\n' strClean = '.c.cpp.o:\n\t$(CC) $(CFLAGS) -c -o $*.o $<\n' msg = ('%s%s\n%s\n%s\n%s') % (msg,str1,str2,str3,strClean) #print 'msg : \n'
#print msg
return msg if __name__ == '__main__': for arg in sys.argv[1:]: print arg str = genMakefileStr(arg) if arg[-1] == '/':arg = arg[:-1] file = open(arg+"/Makefile","w") file.write(str) file.close() print str

把文件genMakefile.py改名为genMakefile,复制到/usr/local/bin下，以后在需要的目录里面执行如下命令即可：

genMakefile .
