小工具, 在使用第三方dll 的时候, 直接用这个python 脚本生成对应dll 的 lib
废话不多说, 直接上代码, 有需要的可以下载附件
# coding:utf-8
import os
import sys
import re
'''
原理:
1. 利用Vs 自带工具Dumobin.exe dump 出导出表 例:dumpbin /EXPORTS example.dll > example.def
2. 将dump 出的调出表修正为标准def 导出文件
3. 调用vs 工程下的lib 工具 链接def, 生成lib库 例:lib /def:example.def /machine:i386 /out:example.dll

tagPath = 'E:\CppProject\wxMSW-3.0.3_vc120_ReleaseDLL\lib\\vc120_dll\lib\\' # 指定生成lib 的目标路径
vsPath = r'D:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\\' #vs 路径, lib.exe 和dumpbin.exe 在该路径下
dumpbinExe = 'dumpbin.exe'
libExe = 'lib.exe'
