我刚刚建立的libpng使用VS2008在64位Windows计算机上。它产生一个 libpng.lib 文件中的\项目\ visualc71 \ Win32_Lib_Release目录（配置为使用LIB发行）。

I just built libpng on a 64-bit Windows machine using VS2008. It produces a libpng.lib file inside the \projects\visualc71\Win32_Lib_Release directory (Configuration used being "LIB Release").

我用 DUMPBIN 来检查这个LIB文件：

I used dumpbin to inspect this LIB file:

C:\Temp\libpng-1.4.3>dumpbin projects\visualc71\Win32_LIB_Release\libpng.lib
Microsoft (R) COFF/PE Dumper Version 9.00.30729.01

Dump of file projects\visualc71\Win32_LIB_Release\libpng.lib

File Type: LIBRARY

  Summary

         8E4 .debug$S
         DF2 .drectve
        2BCD .rdata
       21165 .text

C:\Temp\libpng-1.4.3>

但是，它没有显示出LIB文件的体系结构。如何找到一个给定的LIB文件是专为32位或64位的架构？

It does not however show the architecture of the LIB file. How do I find if a given LIB file is built for 32-bit or 64-bit architecture?

推荐答案

使用DUMPBIN /头

Use dumpbin /headers

本机型几乎与第一线，你会得到。

The machine type is almost the first line you'll get.

这将是14C ​​x86和8664用于基于x64

It will be 14c for x86 and 8664 for x64

N：> DUMPBIN lib642.lib /头

n:>dumpbin lib642.lib /headers
