WebGL always gets stuck building player - building native binary with IL2CPP

EDIT: I was able to solve my issue with publishing to WebGL by disabling the FIPS setting in the regedit. See the thread I created here:
https://forum.unity3d.com/threads/webgl-will-only-publish-with-fips-disabled.468004/


I am using Unity 5.6.0f3, Windows 7 (64-bit), and without fail, the WebGL build always freezes up on the step "Building native binary with IL2CPP". IL2CPP then proceeds to quit.

At first I was using a project that had plugins, such as UFPS and ProCore. I thought those may be the issue, so I tried building to WebGL with a blank project. I still get the same error. Attached is the editor log.

Thanks!

Having the exact same issue in OSX too (Unity 5.6.0f3 as well). Just trying to build the simple Roll A Ball example project, and it gets stuck on that step. Any help would be appreciated

EDIT: Attaching my Editor.log as well

 

Hey I've been getting the same error here and have tried a myriad of fixes with no luck. I had started a separate thread about it here: http://answers.unity3d.com/questions/1337886/webgl-build-error-in-56-problem-with-python-script.html

Something interesting I've found is that I rolled back my version of unity to 5.5 and also 5.4 separately and still get the error, even though I was able to build WebGL with those earlier. That leads me to believe it was a windows update error as shown here: https://forum.unity3d.com/threads/webgl-will-only-publish-with-fips-disabled.468004/

Can anyone else confirm this or roll back their unity to the same effect?

I am having exactly the same issue. It starts off normally and gets stuck at the part where it says
"Building native binary with IL2CPP."
This is really annoying please help someone.

 

Same here...

 

I don't know if this serves any help, but I just tried for the 10th time and suddenly it worked lol

 

I'm having this issue in 2017.1

 

Same, webGL builds only work about 25% of the time for me. Very frustrating.

 

what is frustrating is that no one from unity ever replies as to what is the status of the fix, ever. Unity loves to send promotional emails , but not fix bugs.

It actually takes a very long time in my case to build a webgl project, first i thought that unity has hung, but i just kept waiting, and after a long long time, the project finally got built. so i suggest to everyone to just wait out the build process, it might look like unity is not responding, but it will build the project finally.

 

Same problem here building the Space Shooter tutorial [ Space Shooter tutorial ] in a virtual machine running Parallels Desktop 13 with Windows 10 and Unity version 2017.3.1f1.

The build gets stuck in:

"Building native binary with IL2CPP."

Too bad...

 

Same here

 

Same here

 

This happened to me, too. I'm building for Windows 64bit Standalone. Here's a mini dump file. Hope it helps.

 

Sorry, I already killed the process. I'll post it here when I build again.

 

And oh, I've also tried it in cloud build. It failed with this error:

/BUILD_PATH/.mason/buildpacks/unity/bin/compile:367:in `run_build': ! build failed - export directory is empty! (RuntimeError)
from /BUILD_PATH/.mason/buildpacks/unity/bin/compile:618:in `<main>'
! build of 'test-pc-64bit' failed. compile failed

 

same problem here

 

Same issue here. A "hello world" in unity freezes (flatlines CPU) at the same step

 

Yesterday the same happened to me on 2018.2.10f1. Today I restarted my computer and it happened again. After force quitting unity and trying a second time though, it stayed on "Compile WebAssembly module" for ~10 minutes, but then the build succeeded. Subsequent 2 builds succeeded, and another 2 builds after restarting unity and modifying the game succeeded too. Strange... Maybe I just wasn't waiting long enough on "Building native binary with IL2CPP".

 

For what it is worth, I have a Ryzen 2700x and I just let my computer churn at "building native binary with IL2CPP" for about 4 minutes, then "Compile WebAssembly module" for another 12 minutes and it finally finished. Pretty ridiculous amount of processing time. It is also worth noting that my CPU was pinned at 100% utilization for most of that time and caused complete freezing of my computer.

 

Same problem here, I am using Unity2018.3of2 and gets stuck in:
"BUILDING PLAYER; building native binary with IL2CPP..." I tried like 5 times already but didnt work, always while triyng to build it in WebGL

 

A project that compiles at home in around 4 minutes, has been compiling on my machine here 4 hours.. Theres no idea how far it has got, or not got.. I am finding great resentment for IL2CPP, it feels like a big rework of something .net has mostly done for us in many other ways.

It could be 1 file from completion or just rehashing the same one.. (yes I did find some log file showing some stuff) but when your entire machine has 20% cpu, 30% memory and next to nothing else of value and everything hangs and wont draw properly because unity is compiling, the many hours are incredibly frustrating.. I have an SSD, but cannot change the virus settings to exclude the area

So like the others here, Im on 2018.3.5f1 and while I cant say its hanging, its not getting on with it much either..

 

Hi, it happened to me too but I waited around 20 minutes and it finally finished. I don't think it's a problem, just I can't build to web that often.

 

I cant install many tools on the work pc, however, it’s exactly the same project, turns out compile time at work is 5.5 hours. Everything about the build is the same.

Processes are around the same quantity of python il2cpp et al as my home pc.

While my home pc is a better spec, the main difference is work pc has many work snooping apps on. But things like visual studio compiles for example aren’t noticeably different speeds. Im not sure work would like me to advertise what thy use, however, if you josh would like to discuss over pm some finer details, i will share what i can

 

Same here. (2018.3.10f1)

 

I'm also having this issue on 2018.3.11f1

 

I am on Unity 2018.3.13f1. While I have not gotten a crash yet, it does take quite a while to build my very, very simple project. It is simply a cube that can move left and right. The longest stage is "Building native library with IL2CPP..."

I have not really tried IL2CPP on standalone yet, so I can't say what the build times are for that.

But I must say that 20 minutes for this very simply project is quite the wait. I had a bug in the build that I was unaware of and now I need to wait another 20 minutes to see if the fix even had a chance of working.

 

same here on 2019.1.2f1

 

I changed my workflow. Main rule: everything I do MUST be reproducible in Editor. Debugging in browser I call "Desperation".

 

I can't build WebGL projects at all in Unity 2019.1 Official, or the 2019.2 Beta.

The build process crashes either at IL2CPP compilation, or the stage immediately after that, I forget what it was called.

The crash happens 100% of the time on both the official release, and the Beta. Each crash causes a BSOD on my machine, (Windows x64). This happens 100% percent of the time I try to build anything in WebGL, even plain Jane blank projects.

The BSOD returns a paging error most of the time (makes no sense to me, my comp shouldn't be paging stuff at all as far as I know)

I assume the problem must be on my end seeing as no one else is crying about it, but not really sure what else to try?

 

Same here. I get stuck at "Compile WebAssembly module" when compiling for WebGL on 2018.3.14f1

 

Be patient, Unity will build it eventually. It also freeze at Compile WebAssembly module ,it takes me like 10 min to build a relatively small project 50mb, Unity goes unresponsive, it shows as Not responding in the task manager, but it will finish, just set it and forget it.

 

Updating to Unity 2019.1 and installing all necessary modules fixed the problem.

 

having this issue with 2019.2.2f1 publishing for Android

 

Me toooo! Please help!!

 

I still have this problem please help!!!

 

I'm macOS, what can I do to build this?

 

And when I'm trying to build, in reality I thinks it is building a .yaml file (that I don't know what it is), but I'm not sure, the only thing that I know is that unity stops building when says "Building native binary with IL2CPP" and then that error occurs

 

The error message is UnityEditor.BuildPlayerWindow+BuildMethodException: 3 errors

 

First error: is the one related to il2cpp, which says that il2cpp didn't run properly. And appears all that text that I sent you before.

Second error: Build completed with a result of 'Failed'.
