Undefined preprocessor variable '$(var.LedControl.TargetDir)'

[anders-eriksson]

Hello,
I have just installed Wix 3.11.1 and Wix Toolset Visual Studio 2017 Extension and Wax 1.4.1788 from Visual Studio Marketplace.

I have then follow your instructions but the build fails with and error
Undefined preprocessor variable '$(var.LedControl.TargetDir)'

It seems like the File Mappings are a bit strange (or probably I'm doing something wrong)
After clicking on + for each file I get a number of defines in Project.wxs
This is what it looks like in Wix Setup Editor

This is whats added to the Project.wxs

As you can hopefully see there are some variables used that isn't defined.
LedControl
Contracts
Data
LighterWrapper
Configuration
DCLog
Profile

These are all referenced projects!

How would I fix this?

See https://wixtoolset.org/documentation/manual/v3/votive/votive_project_references.html
Usually Wax should have added project references for all these projects. This seem to have failed in your case, so just add them manually.

I saw this same issue with the newest release. I had to revert to an older version to get things to work properly.
