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

Unity Engine
1

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:

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

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: WebGL build error in 5.6 problem with python script - Questions & Answers - Unity Discussions

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: WebGL will only publish with FIPS disabled - Unity Engine - Unity Discussions

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

Do you get the same error: “This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms.” ?

5

yours seems a different issue but I can’t tell from the log.

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.

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

11

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

12

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.

Any specific bug? If you post the bug number here, I am happy check the status for you (or perhaps create a new thread if it’s not related to this one)

14

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… :frowning:

Can you use a tool like Process Explorer (https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer) to capture the process tree below Unity.exe when this happens? That might help us understand what is causing the problem,.

Same here

@hikke @Chris85s

Can you use the tool I mentioned above to gather any additional information?

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

@davenirline

Thanks for the information. Usually the time is not spent in the Unity.exe process, but in one of its child processes. For a Windows standalone build, that will probably be in a cl.exe process (the C++ compiler). Can you drill down to that process? The key thing we need is its command line arguments, so we can see what source file is taking too long to compile.
