你可能有一个针对x64(这是模块机器类型)的. obj或. lib文件，而你链接的是x86(这是目标机器类型)。

在. obj文件上使用DUMPBIN /HEADERS，并在FILE HEADER VALUES块中检查机器条目。

当我遇到这个令人抓狂的问题时，我写了一篇关于这个问题的博客文章，并最终将我的系统恢复到正常工作状态。

以下是需要检查的事项，按顺序:

Check your properties options in your linker settings at: Properties > Configuration Properties > Linker > Advanced > Target Machine. Select MachineX64 if you are targeting a 64 bit build, or MachineX86 if you are making a 32 bit build. Select Build > Configuration Manager from the main menu in visual studio. Make sure your project has the correct platform specified. It is possible for the IDE to be set to build x64 but an individual project in the solution can be set to target win32. So yeah, visual studio leaves a lot of rope to hang yourself, but that's life. Check your library files that they really are of the type of platform are targeting. This can be used by using dumpbin.exe which is in your visual studio VC\bin directory. use the -headers option to dump all your functions. Look for the machine entry for each function. it should include x64 if it's a 64 bit build. In visual studio, select Tools > Options from the main menu. select Projects and Solutions > VC++ Directories. Select x64 from the Platform dropdown. Make sure that the first entry is: $(VCInstallDir)\bin\x86_amd64 followed by $(VCInstallDir)\bin.

一旦我完成了第4步，一切都恢复正常了。问题是我在我所有的项目中都遇到了这个问题，我想编译一个64位的目标。

如果您的解决方案有库项目，请检查属性->图书管理员->通用中的目标机器属性

我通过在Visual Studio 2013中将Win32更改为*64来解决这个问题。

对于一些使用命令提示符(dos提示符)的用户 这可能会有帮助:

call "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" --help
Error in script usage. The correct usage is:
    "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" [option]
  or
    "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" [option] store
  or
    "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" [option] [version number]
  or
    "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" [option] store [version number]
where [option] is: x86 | amd64 | arm | x86_amd64 | x86_arm | amd64_x86 | amd64_arm
where [version number] is either the full Windows 10 SDK version number or "8.1" to use the windows 8.1 SDK
:
The store parameter sets environment variables to support
  store (rather than desktop) development.

For example:
    "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x86_amd64
    "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x86_arm store
    "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x86_amd64 10.0.10240.0
    "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x86_arm store 10.0.10240.0
    "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x64 8.1
    "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x64 store 8.1

Please make sure either Visual Studio or C++ Build SKU is installed.

如果你这样做:

CL "%1%2%3" /EHsc /链接user32。自由Gdi32。自由Winmm。自由comctl32。自由*。obj /子系统:CONSOLE /MACHINE:x86

你必须取消*。obj之前;为了避免混淆链接器与64和32位对象从以前的编译遗留下来?
