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。
#! /usr/bin/python ''' File : genMakefile.py Author : Mike E-Mail : Mike_Zhang@live.com ''' 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
运行效果如下(示例):
# ./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 $<
运行脚本后进行make即可。
附:
感觉上面的那个脚本用着不方便,随后修改修改,代码如下:
#! /usr/bin/python ''' File : genMakefile.py Author : Mike E-Mail : Mike_Zhang@live.com ''' import os,sys surfix = ['.c','.cpp'] def genMakefileStr(dir): msg = '' msg = msg + 'CC = g++ ' + '\n' msg = msg + 'CFLAGS = -g -O2 -Wall' + '\n\n' fList = [] for dirPath,dirNames,fileNames in os.walk(dir): for file in fileNames: name,extension = os.path.splitext(file) if surfix.count(extension) > 0: fList.append(name) break # only search the current directory str1 = 'all:\n' str2 = '' str3 = 'clean:\n' for f in fList: str1 = str1 + '\tmake ' + f + '\n' str2 = ('%s%s:%s.o\n') % (str2,f,f) str2 = ('%s\t$(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 .
