代码在这里，功能有限（适用于单个文件是一个的测试代码的情况），需要的朋友可以稍作修改以满足需求。

代码如下:

def genMakefileStr(dir,surfix = '.c'):
msg = ''
msg = msg + 'CC = gcc' + '\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 extension == surfix:
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$(CC) -o %s %s.o\n\n') % (str2,f,f)
str3 = ('%s\trm -f %s\n') % (str3,f)
str3 = str3 + '\trm -f *.o\n'
strClean = '.c.o:\n\t$(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__':
str = genMakefileStr('.','.c')
file = open("Makefile","w")
file.write(str)
file.close()
print str

运行效果如下（示例）：

代码如下:

all:
make pfun1
make pfun2

pfun1:pfun1.o
$(CC) -o pfun1 pfun1.o

pfun2:pfun2.o
$(CC) -o pfun2 pfun2.o

clean:
rm -f pfun1
rm -f pfun2
rm -f *.o

.c.o:
$(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：
代码如下:

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 .
