Compiling in VisualStudio after building in Unity with Vuforia included

Hi!

I want to finish a project until next friday.
Since I have to use Windows as the platform and Vuforia should only work on Windows if built for Universal Windows Platform I tried that: I installed Windows 10 SDK, switched in Build Settings to UWP and used following settings:


After building I open it in Visual Studio and click 'Start'. Then I get 2 errors. One of them:

(file [...]Plugin\\VuforiaDL.dll was not found)
But it is actually inside the project. I was confused by that \\ and it seems that the correct path is 'Plugin\[x86 or x64]\VuforiaDL.dll.

So far I tried to play around with the settings inside unity, nothing helped though.
Could anyone give me a hint what I could do?

Thanks,
Andy

 

My guess is the x86/x64 in the path is produced by a VisualStudio environment variable that's missing and evaluates to an empty string.

I suggest opening the VS project in a text editor and locate that path for the "VuforiaDL.dll" to see exactly how it's represented. You can either fix the variable (if that's the case) or simply hard code the correct path.

It could be a Unity bug in the UWP project generation, but I can't say with this information. If you determine the bad path is coming from Unity, please open a bug for it.

 

Hi!
Thank you for your response. I opened the .sln inside the rootdirectory but there is ofc no further information. I am not sure what you mean by 'open project inside a text editor'.
Therefor I opened the porject inside VisualStudio. I searched for VuforiaDL and found some files with Vuforia in them. But no file contained VuforiaDL. But there is Unity Date about a VuforiaDL.dll with an incorrect path. Cant edit it though...

Here is a screenshot of the files I found

 

VisualStudio project files (e.g. .csproj or .vcxproj) are just XML text files that are basically scripts for MSBuild. So you can open and edit them directly in order to view/edit project contents and settings. The Solution file (.sln) is just a container that references one or more projects but doesn't contain any real information itself (so ignore .sln file).

Here's the easiest way to edit your Unity VS project files:
1. Open your project in VS normally
2. Assuming you built for UWP you have 3 projects: "Il2cppOutputProject", "UnityData", and your actual Unity project (which I'm going to call "Faszien" here)
3, Right-click on your Unity project, i.e. "Faszien", and select "Unload Project" from the drop down menu
4. Right-click on the project again and select "Edit 'Faszien'.vcxproj

This will open the project file as an XML document, which you can now review and edit. Examine this file for VuforiaDL.dll references and see if the file paths make sense.

 

Thank you for your support!
I couldnt find a VuforiaDL.dll but several directories. A lot of them defined by variables but none seem to show the directory the dll is in (Faszien\bin\maniptest\Plugins\x86).

Code (CSharp):

1.   <PropertyGroup>
2.     <OutDir>$(SolutionDir)build\bin\$(Platform)\$(Configuration)\</OutDir>
3.     <IntDir>$(SolutionDir)build\obj\$(MSBuildProjectName)\$(Platform)\$(Configuration)\</IntDir>
4.     <AppxBundle>Auto</AppxBundle>
5.   </PropertyGroup>
6.  

Code (CSharp):

1.  <ItemDefinitionGroup>
2.     <ClCompile>
3.       <AdditionalOptions>/bigobj %(AdditionalOptions)</AdditionalOptions>
4.       <DisableSpecificWarnings>4447;4453;4451;4691;28204</DisableSpecificWarnings>
5.       <PreprocessorDefinitions>_UNICODE;UNICODE;%(PreprocessorDefinitions)</PreprocessorDefinitions>
6.       <AdditionalIncludeDirectories>$(ProjectDir);$(GeneratedFilesDir);$(IntDir);$(SolutionDir)Il2CppOutputProject\Source\CppPlugins;%(AdditionalIncludeDirectories)</AdditionalIncludeDirectories>
7.     </ClCompile>
8.     <Link>

HI!
Yes, found it in that file. 2 sections include a path to this file:

Code (CSharp):

1.     <None Include="$(MSBuildThisFileDirectory)VuforiaDL.dll">
2.       <DeploymentContent>true</DeploymentContent>
3.       <ExcludeFromResourceIndex>true</ExcludeFromResourceIndex>

Code (CSharp):

1.         <Copy SourceFiles="$(ProjectDir)Plugins\$(PlatformShortName)\VuforiaDL.dll" DestinationFiles="$(ProjectDir)VuforiaDL.dll" />
2.             <Delete Files="$(ProjectDir)VuforiaDL.pdb" Condition="Exists('$(ProjectDir)VuforiaDL.pdb')" />
3.             <Delete Files="$(ProjectDir)VuforiaDL.dll.mdb" Condition="Exists('$(ProjectDir)VuforiaDL.dll.mdb')" />
4.             <Copy SourceFiles="$(ProjectDir)Plugins\$(PlatformShortName)\VuforiaDL.pdb" DestinationFiles="$(ProjectDir)VuforiaDL.pdb" Condition="Exists('$(ProjectDir)Plugins\$(PlatformShortName)\VuforiaDL.pdb')" />
