LGHT0094: Unresolved reference to symbol 'WixComponentGroup:Product.Generated' in section 'Product:*'

Question

I'm having this error on one of build servers. All other servers build it ok. Any ideas what can be wrong?

Answer 1

Its a wix 3.6 issue. Found the solution here. All you need to do is add the following property <EnableProjectHarvesting>True</EnableProjectHarvesting> on your wix project

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <EnableProjectHarvesting>True</EnableProjectHarvesting>

Answer 2

I also had this error, It seems to be a new thing automatically generated from Wix when a new setup is created. Wix did not like it when I upgraded from 3.5 to 3.6, i simply deleted it.

Answer 3

In my case, I should use ComponentRef instead of ComponentGroupRef

Answer 4

After an upgrade from Wix 3.5 to Wix 3.8, we got the same issue. However, we do not want project harvesting, so setting EnableProjectHarvesting to true is not a good solution. So to solve the problem, we had to change a couple things :

In the file Product.wxs, we removed completely the following line (from the attribute <Feature>) :

<ComponentGroupRef Id="Product.Generated" />

After that, in our .wixproj, we updated the LinkerBaseInputPaths to a DefineConstants.

So this means change

<LinkerBaseInputPaths>%(ProjectReference.RootDir)%(ProjectReference.Directory)obj\$(Configuration)\Package\PackageTmp\</LinkerBaseInputPaths>

To (And please also notice the addition of BasePath=%)

<DefineConstants>BasePath=%(ProjectReference.RootDir)%(ProjectReference.Directory)obj\$(Configuration)\Package\PackageTmp\</DefineConstants>

and finally we added

PreprocessorVariable="var.BasePath"

to our HeatDirectory attribute (which is just below the PropertyGroup we modified in the previous step).

Answer 5

In my case, I was getting the same error number:

file_name.wxs(38): error LGHT0094: Unresolved reference to symbol 'WixComponentGroup:Name_of_the_ComponentGroup

This was because I had moved the ComponentGroup to a different file, and the build script (cmake in my case, maybe you use ant) that calls candle.exe had not been updated to include the .wxs file that now contained the ComponentGroup.

Updating the cmake script to include the new file fixed the error. And the error message was actually meaningful, since this was an unresolved reference.
