Determining the CPU architecture of a static library (LIB) on Windows
提问by Sridhar Ratnakumar
I just built libpng on a 64-bit Windows machine using VS2008. It produces a libpng.libfile inside the \projects\visualc71\Win32_Lib_Release directory (Configuration used being "LIB Release").
我刚刚使用 VS2008 在 64 位 Windows 机器上构建了 libpng。它libpng.lib在 \projects\visualc71\Win32_Lib_Release 目录中生成一个文件（使用的配置为“LIB Release”）。
I used dumpbinto inspect this LIB file:
我曾经dumpbin检查过这个 LIB 文件：
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>
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?
然而，它没有显示 LIB 文件的架构。如何确定给定的 LIB 文件是为 32 位还是 64 位架构构建的？

Use dumpbin /headers
使用 dumpbin /headers
The machine type is almost the first line you'll get.
机器类型几乎是您将获得的第一行。
It will be 14c for x86 and 8664 for x64
x86 为 14c，x64 为 8664
