在linux下寫幾個(gè)測(cè)試程序，還要一行行的輸入g++命令進(jìn)行編譯，當(dāng)經(jīng)常改測(cè)試代碼的時(shí)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(gè)腳本，其功能是自動(dòng)搜索當(dāng)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（適用于單個(gè)文件是一個(gè)獨(dú)立的測(cè)試代碼的情況），需要的朋友可以稍作修改以滿足需求。

復(fù)制代碼代碼如下:

#! /usr/bin/python
'''
File      : genMakefile.py
Author    : Mike
E-Mail    : [email protected]
'''
import os

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

運(yùn)行效果如下（示例）：

復(fù)制代碼代碼如下:

# ./genMakefile.py
CC = gcc
CFLAGS = -g -O2 -Wall

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 $<

運(yùn)行腳本后進(jìn)行make即可。

附：

感覺上面的那個(gè)腳本用著不方便，隨后修改修改，代碼如下：
