在linux下寫幾個測試程序，還要一行行的輸入g++命令進行編譯，當經常改測試代碼的時候，那一次次的敲（或者一次次的上線箭頭選）也感覺不爽，不如make來的快。用Makefile的好處就不用多說了，這里我寫了個腳本，其功能是自動搜索當前目錄（不包括子目錄）下的“.c”文件生成Makefile文件。
代碼在這里，功能有限（適用於單個文件是一個獨立的測試代碼的情況），需要的朋友可以稍作修改以滿足需求。

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
運行效果如下（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 $<
運行腳本后進行make即可。
附：
感覺上面的那個腳本用着不方便，隨后修改修改，代碼如下：
#! /usr/bin/python ''' File : genMakefile.py Author : Mike E-Mail : Mike_Zhang@live.com ''' import os,sys surfix = ['.c','.cpp'] def genMakefileStr(dir): msg = '' msg = msg + 'CC = g++ ' + '\n' msg = msg + 'CFLAGS = -g -O2 -Wall' + '\n\n' fList = [] for dirPath,dirNames,fileNames in os.walk(dir): for file in fileNames: name,extension = os.path.splitext(file) if surfix.count(extension) > 0: fList.append(name) break # only search the current directory str1 = 'all:\n' str2 = '' str3 = 'clean:\n' for f in fList: str1 = str1 + '\tmake ' + f + '\n' str2 = ('%s%s:%s.o\n') % (str2,f,f) str2 = ('%s\t$(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改名為genMakefile,復制到/usr/local/bin下，以后在需要的目錄里面執行如下命令即可：
genMakefile .
