產生簡單的Makefile檔案(Python實現)

在linux下寫幾個測試程式，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，這裡我寫了個指令碼，其功能是自動搜尋目前的目錄（不包括子目錄）下的“.c”檔案產生Makefile檔案。
代碼在這裡，功能有限（適用於單個檔案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。

 7 import os
 8 
 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（樣本）：

 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 $<

運行指令碼後進行make即可。

附：

感覺上面的那個指令碼用著不方便，隨後修改修改，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

把檔案genMakefile.py改名為genMakefile,複製到/usr/local/bin下，以後在需要的目錄裡面執行如下命令即可：

genMakefile .
