Official Burst for standalone players

FIRST! can it be used outside the job system? if so I will test it asap

 

Can it be used with the Incremental Compiler? Or does it has any issue ?

 

Apparantently I will be the last one to try it

 

Is there an ETA on Burst for Nintendo Switch?

 

Does it work with jobs outside of the ECS? I successfully used the job system for procedural Generation and now I want to experiment with the burst compiler as well. I added the package and put the [BurstCompile] attribute over a job struct, but it can't compile as it can't find the attribute. The only attribute found is BurstDiscard.

I'm on 2018.2 and use the incremental compiler and assembly definition files.

 

Thanks for the answer, but like I said, I have the package already installed from the package manager. The file is even there in the project browser, but even with including "Unity.Burst" the compiler can't seem to find the attribute. The Editor Tools coming with the Burst package seem to run fine though. I can open the Burst Job Inspector and so on. I simply can't compile any jobs, as the BurstCompile attribute is not recognized for some weird reason. I have the suspicion it might be related to assembly definition files, but I am not sure.

 

Any ETA on when the assemblies from packages will be available in the selection menu for references? Right now, in order to add a dependency to Unity.Burst, you have to open the asmdef file in a text editor.

 

you can drag it from the project folder if you have 2018.2 (under "Packages")

 

Ah that makes sense, thank you. I already thought about doing that, but as it didn't show up in the drop down menu, I thought it might not be the case. Thank you very much!

 

Maybe add to the documentation that Windows SDK and VC++ toolset has to be installed in order for burst to work in builds.

 

Thanks, and good idea! However, even after installing the sdk and vc++ I still get this error.I am on windows 10, VS2017, Unity 2018.2.2f1 and on Burst 0.2.4-preview.23

These are the components I installed to remedy above error some months ago:



I don't remember the defaults, but perhaps the CLI (command line interface) is also necessary?

Did you add the IL2CPP Windows build target inside Unitys installer?

Other than that, try a restart of Windows :|


@Unity: does posting "internal errors" reported in the console when using Burst help you? Such as :

Hi, nice, thank you. Do you mean

public void I....Execute(…)

? This yields error "CS0106: The modifier `public' is not valid for this item"

 

Actually,

public void Execute(int index, TransformAccess transform)

, without specifying the interface explicitly.

 

Thank you, this "did the job": the error is gone.

 

I'm getting a lot of errors referring to UnityEngine.Mathf, even after removing all references to Mathf, why is that?

 

I'm getting a linking error trying to build with the burst compiler. It complains about missing MsWSock.lib which is in my SDK/Windows/7/lib dir but not the /8 dirs (which I think it's actually using). Not sure how I fix this?

I have VS2017 (along with earlier versions)... and it is VS2017 that I'm using with Unity. I guess the burst compiler is using the wrong Windows SDK, which I'm not sure how to change. I'm pretty sure I don't need any of those earlier versions so I'll just remove them and see if that fixes it.

 

Heh. So removing VS2013 / VS2015 leads to me getting this error from the linker:

Failed running C:\Users\Playtech\AppData\Local\Unity\cache\packages\packages.unity.com\com.unity.burst@0.2.4-preview.31\.Runtime\bcl.exe @C:\Users\Playtech\AppData\Local\Temp\tmp2e40c9d.tmp

...but I definitely do still have VS2017 installed. So, this looks like an error with the IL2CPP toolchain not finding the MSVC installation for VS2017?

 

I'm in the same situation, VS2017, WindowsSDK, VC ++, IL2CPP, Burst 0.2.4 preview31

What are the requirements to build with burst?

Why its say "No MSVC installations were found on the machine"?

 

It's working now, and what a performance, good job for everyone involved.

I'm not sure what solved it, but just updated visual studio and SDKs using VS.

 

For anybody having similar problems. There are actually a couple of situations where similar exceptions pop-up, not necessarily related to the use of explicit interface implementation.

There's a bug in DevirtualizeMethod() implementation that confuses generic parameters from the caller context and callee context. So then if it so happens that there is a generic parameter T in the caller context and a generic parameter T in callee context and they are not substituted for the same thing, then Burst will fail to resolve method definition. A workaround is to just rename generic parameters on one of the sides.

 

Are there any plans to support delegates that only reference static functions?

I think this would open up many design possibilities for the Job System. For example quickly specifying an ECS systems behavior with delegates.

I am aware of the 'static delegates' proposal https://github.com/dotnet/csharplang/issues/302 but we can only guess when to expect that.

Side note: I was able to produce generic static delegates in IL with the calli opcode. But they are reasonably brittle without proper lang support.

Edit: I just realized that if Burst was to support calli, I could flesh out my static delegates experiments and use that. Although I guess that would be pretty unsafe to use in actual builds.

 

The burst compiles AOT right? So does it produce CPP code?

 

I'm bumping into the Win10 SDK search problem on Unity 2018.2.14f1 with com.unity.burst@0.2.4-preview.34 and Visual Studio Community 2017 with options installed that should cover this scenario, and then some.

Which search criteria is blink.exe/bcl.exe passing to the Microsoft.VisualStudio.Setup.Configuration COM APIs?

Is there are hard requirement on NETFXSDK 4.6.1? I would think you would want it to find anything >= some min version.

Spying on blink.exe; The Win10 SDK path it hits, feels antiquated/deprecated. Hmm.




Any suggestions?

- appreciated


EDIT: PLEASE DISREGARD.
I'm looking at a very broken Visual Studio 2017 installation, where Window Installer packages for various SDKs are installed, but their Features/Components we're never flagged for install. That feels like a problem with the VS setup chainer. Forcing all features to fail-in for select packages is one fix. For example...

C:\Windows\Installer>msiexec -i 28f6800.msi -l*vx TEMP.log VSEXTUI=1 ADDLOCAL=ALL

... but I'll force all VS-deployed packages off the system and then re-install. Apologies for the noise.

Thanks all !
I have compile the script successfully and all exceptions which about the burst are now disappear.
I reinstall vs2017 and almost its all component (except something obviously doesn't look like related, such as nodejs,asp etc.)

 

I have this very same problem. The burst compiler runs fine in editor but fails on build. When building using IL2CPP, I get the following errors:

These errors appear in order on Console...

I already updated my Visual Studio and added VS components through Unity Hub. Is there anything else that I can do with this?

 

for @davenirline's issue, it's covered here already: https://forum.unity.com/threads/burst-doesnt-seem-to-work-in-development-build.579607/#post-3864880, no need to crosspost.

 

@davenirline I have replayed you here.

Hi there, is support for jobs/burst coming to UWP anytime soon?

 

Is cross-platform compilation support coming in a future release? When using burst I can only compile a Mac client on macOS and a windows client on windows which throws a wrench in my build pipeline.

Hi, we are enabling burst compiler for our job systems but encountered incorrect behavior when converting constant uint values to ulong. Basically this:

Code (CSharp):

1. ulong value = uint.MaxValue;

will produce incorrect result 18446744073709551615 when burst is enabled.

I have posted more details in https://forum.unity.com/threads/bug...en-converting-uint-constants-to-ulong.584173/ but haven't gotten any replies there yet.

 

I just would like to say, I am amazed even more with burst.
Running current stress test for my project and difference is by miles better with burst.

 

Using Jobs+Burst to power a little physics engine, seeing some weird stuff with a large IJob that I have.

In Unity 2018.3.0b11 my job is throwing errors when I try to build a Windows or Arm7 player.

In 2018.2, on Arm7, the job runs but seems to be skipping/altering some code deep in the job, so I get different effects on x64/Windows vs arm7/Android.

The errors:

Any way to dive deeper and see what the problems are? I'm able to generate assembly for arm7 in the Burst Inspector, so, I'm at a dead end. I can't post too much code publicly, but I'd be happy to share a little repro project with the developers if it's helpful! Thanks!
