如何在我的 vcxproj 文件中打印完整的 cl.exe 路径？

Question

For a custom build target, I would like to have full path with correct version of cl.exe which is being called in ClCompile target.

From retrieve path to cl.exe , I get it is %VCINSTALLDIR%\\bin\\x86\\Hostx86\\cl.exe or %VCINSTALLDIR%\\bin\\x64\\Hostx64\\cl.exe , But I do not want to write program for x84 vs x64 logic.

In VCTargets\\Microsoft.CppCommon.Targets, I find that there is property ToolExe and ToolPath are being set to $(CLToolExe) and $(CLToolPath).

Overriding these properties also changed the path to compiler successfully for me, so it's correct that these are the properties names. Override Compiler in MSBuild

But when I try printing %(CL.ToolPath) or $(CLToolPath) in my custom target exec class, it prints nothing. I also looked in Visual Studio and couldn't find where it was being set.

Is there a variable which can provide cl.exe full path or is there any way I can print property ToolPath of CL Task in my custom target?

Answer 1

1) If you already uses the $(CLToolExe) and $(CLToolPath) to set your new cl.exe and then want to get the full path of it, you should use this $(CLToolPath)$(CLToolExe) to get the new value rather than %(CL.ToolPath) (there is no such way like this).

This is my test result:

Actually , you can overwrite these properties directly under your xxx.csporj file rather than in Microsoft.CppCommon.Targets file and when you build your project, it will use the new cl.exe .

Then , I use a custom target to get the value:

<Target Name="test123" AfterTargets="ClCompile">
        <Exec Command="$(CLToolPath)$(CLToolExe)" />
        <Message Importance="high" Text="$(CLToolPath)$(CLToolExe)"></Message>
</Target>

2) If you did not change to the new value and use the default cl.exe without any changes, you should use $(ClCompilerPath) to get the default value.

 <Target Name="test123" AfterTargets="ClCompile">       
       <Message Importance="high" Text="$(ClCompilerPath)"></Message>
 </Target>

Note : $(ClCompilerPath) cannot get the new value of $(CLToolPath)$(CLToolExe) since they are not related and can only get the default value.
