Python列出文件依赖的动态链接库

使用Python 打印出文件依赖的动态链接库

#ldd.py


import subprocess
import sys
import os


def ldd(filename):
	global libs
	libs = [] 
	for x in filename:
		p = subprocess.Popen(["ldd", x], 
			stdout=subprocess.PIPE,
			stderr=subprocess.PIPE)

		result = p.stdout.readlines()


		for x in result:
			s = x.split()
			if "=>" in x:
				if len(s) == 3: # virtual library
					pass
				else: 
					libs.append(s[2])
			else: 
				if len(s) == 2:
					libs.append(s[0])

	return libs 
	
if __name__ == "__main__":
	if len(sys.argv) <= 1:
		print("usage: %s filename1 filename2 ..."%(sys.argv[0]))
	else:
		print("\n".join(ldd(sys.argv[1:])))

可以使用一下的命令将文件依赖的动态链接库复制到指定的文件夹中： 

./ldd.py file | xargs -i cp {} ./libs

复制file所依赖的动态链接库到libs目录中
