32/64 位的 MSBuild 和 $(ProgramFiles) 问题 [英] MSBuild and $(ProgramFiles) issue with 32/64 bits

问题描述

我编写了一个调用 SubWCRev.exe 的自定义 MSBuild 任务，一个可执行文件(通常)驻留在 C:Program FilesTortoiseSVNin 中，无论是 32或 64 位，因为 TortoiseSVN 提供这两个版本.

I wrote a custom MSBuild task which calls SubWCRev.exe, an executable which (typically) resides in C:Program FilesTortoiseSVNin, whether it's 32 or 64 bits, since TortoiseSVN provides both versions.

问题是，Visual Studio 2010 只有 32 位版本.因此，当我使用 64 位机器的同事尝试使用我闪亮的新任务进行构建时，$(ProgramFiles) 解析为 C:Program Files(x86) 并且它爆炸说找不到 SubWCRev.exe.因为他们有 64 位版本的 TortoiseSVN，它位于 C:Program Files！

The problem is, Visual Studio 2010 only has a 32 bit version. So when my colleagues with a 64 bit box try to build using my shiny new task, $(ProgramFiles) resolves to C:Program Files(x86) and it explodes saying that SubWCRev.exe cannot be found. Because they have the 64 bit version of TortoiseSVN, which lives in C:Program Files!

是否有比在我的 msbuild 脚本中硬编码 C:Program Files 或让每个人都使用 32 位版本的 TortoiseSVN 更好的解决方案?(其实是C#项目，MSBuild代码稍微修改了一下)

Is there a better solution than hardcoding C:Program Files in my msbuild script, or having everyone use the 32 bit version of TortoiseSVN? (Actually it's a C# project, I tinkered with the MSBuild code a bit)

推荐答案

看看这个:

<Project ToolsVersion="4.0" DefaultTargets="PrintValues" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

  <Target Name="PrintValues">
    <PropertyGroup>
      <MyProgramFiles>$(ProgramW6432)</MyProgramFiles>
      <MyProgramFiles Condition="$(MyProgramFiles) == ''">$(ProgramFiles)</MyProgramFiles>
    </PropertyGroup>

    <Message Text="MyProgramFiles: $(MyProgramFiles)"/>
  </Target>

</Project>

这让 MyProgramFiles 解析为 32 位和 64 位 Windows 的C:Program Files"(ProgramW6432 环境变量在非 64 位版本的 Windows视窗).

This lets MyProgramFiles resolve to "C:Program Files" for both 32 and 64 bit Windows (The ProgramW6432 environment variable is empty on non-64 bit versions of Windows).
