HoloToolkit build error (SessionManagerUniversal.UI post build)
Hi,
I'm trying to build HoloToolkit/Sharing using BuildAll.bat (on Windows), and I am always getting this post build error.
"C:\projects\HoloSDK\HoloToolkit\Sharing\Src\Solutions\VisualStudio\HoloToolkit.Sharing.sln" (rebuild target) (1) ->
"C:\projects\HoloSDK\HoloToolkit\Sharing\Src\Projects\SessionManagerUniversal.UI\SessionManagerUniversal.UI.csproj" (Rebuild target) (14) -> PostBuildEvent target) ->
C:\Program Files (x86)\MSBuild\14.0\bin\Microsoft.Common.CurrentVersion.targets(4714,5): error MSB3073: The command "mkdir Appx\r [C:\projects\HoloSDK\HoloToolkit\Sharing\Src\Projects\SessionManagerUniversal.UI\SessionManagerUniversal.UI.csproj]

If I use Visual Studio, it does not show the error. But, the interesting thing is, either way, SharingClient.dll is never built. (Or, at least it's not created under ClientUniversalCSharp as far as I can tell.)
Any tips on how to fix this problem?
Thanks,
~h

@holodoctor looking at the build script I can see that it tried to build the project in multiple configurations - debug/release and architectures ARM/x86/x64. You need to check that all those configurations have the allow unsafe code flag set.
It's weird because I can compile on my end and looking at my git status it looks like I'm up to date with the origin.5 -

I finally fixed the problem, after painful process of trials and errors
of repeating the builds again and again (after incrementally modifying the post-build script each time).First, this is such a weird error. If you look at the error message included in my original question, the error message appears to suggest that the build script treats the Windows eol (\r\n) as a path segment "\r" (file or folder named "r") plus a new line (\n). So bizarre... I replaced all line endings to Unix style.
Second, there was also a simple error. I just included the source file path (which includes "..\") in double quotes.
Now BuildSharingLib.bat runs without errors.
Here's my modified version of the post build script:
if not exist Appx mkdir Appx copy /b/y "..\ClientUniversalCSharp\SharingClient.dll" Appx\SharingClient.dll if $(ConfigurationName) == Debug ( copy /b/y "..\ClientUniversalCSharp\SharingClient.pdb" Appx\SharingClient.pdb )Thanks for the help, @AlexD.

Are you compiling the batch file from an admin VS developer command prompt?
Hi, @neerajwadhwa thanks for the suggestion. Running vsdevcmd with "Run as Administrator" did not help. The build failed at the same point.
The ClientManagerUniversal.UI has a post build command to copy SharingClient.dll to the Appx folder. So if that files does not get created that step will fail. I would open the solution is visual studio and try to compile the ClientUniversalCSharp project and see why it does not build.
A prerequisite to building the projects is to compile all the dependencies with the BuildDependencies.bat command.

@AlexD I don't seem to have problems building via Visual Studio. I can also separately run BuildDependencies with no issues. It's BuildSharingLib that causes problems. The original problem I reported here seems to be a CWD issue (because SharingClient.dll is actually created under Sharing/Src/bin/...). I temporarily commented out the post-build command, and tried running the BuildSharingLib script, and I got other errors (which again I didn't see when I used VS).
At this point, I've sort of given up using the build scripts. New error, for instance:
"c:\Projects\HoloSDK\HoloToolkit\Sharing\Src\Solutions\VisualStudio\HoloToolkit.Sharing.sln" (rebuild target) (1) -> "c:\Projects\HoloSDK\HoloToolkit\Sharing\Src\Projects\SessionManagerUniversal.UI\SessionManagerUniversal.UI.csproj" (Rebuild target) (12) -> (XamlPreCompile target) -> GeneratedFiles\CSharpAPI\AnchorDownloadRequest.cs(58,22): error CS0227: Unsafe code may only appear if compiling with /unsafe [c:\Projects\HoloSDK\HoloToolkit\Sharing\Src\Projects\SessionManager Universal.UI\SessionManagerUniversal.UI.csproj] GeneratedFiles\CSharpAPI\ImageTagManager.cs(45,22): error CS0227: Unsafe code may only appear if compiling with /unsafe [c:\Projects\HoloSDK\HoloToolkit\Sharing\Src\Projects\SessionManagerUniver sal.UI\SessionManagerUniversal.UI.csproj] GeneratedFiles\CSharpAPI\NetworkInMessage.cs(77,22): error CS0227: Unsafe code may only appear if compiling with /unsafe [c:\Projects\HoloSDK\HoloToolkit\Sharing\Src\Projects\SessionManagerUnive rsal.UI\SessionManagerUniversal.UI.csproj] GeneratedFiles\CSharpAPI\NetworkOutMessage.cs(69,22): error CS0227: Unsafe code may only appear if compiling with /unsafe [c:\Projects\HoloSDK\HoloToolkit\Sharing\Src\Projects\SessionManagerUniv ersal.UI\SessionManagerUniversal.UI.csproj] GeneratedFiles\CSharpAPI\RoomManager.cs(87,22): error CS0227: Unsafe code may only appear if compiling with /unsafe [c:\Projects\HoloSDK\HoloToolkit\Sharing\Src\Projects\SessionManagerUniversal.

I have absolutely no idea why the build scripts cause this error when building inside the VS works just fine.
Anyways, thanks for the help,

@AlexD you are right. Apparently I missed one platform when I checked off "allow unsafe code" in release builds. (I do remember this was already set for debug builds.) I updated this setting, and now the build works. (I still have to figure out the post-build error though, but maybe later.) Thanks, ~h
the post build should work if the SharingClient.dll exists. Let me know if you still have issues. The SharingManagerUniversal.UI won't work without that postbuild step (I was among the ones who contributed that piece to the repo).
