Did you figure this problem out? I'm experiencing it on linux

 

I have the same issue in 2018.2.2f1 but only when doing a development build. Would be great to find a solution so I can profile my game in a browser.

 

I Have The Same Problem ,who can help us?

 

Yep, same for me with 2018.2.3f1
Can't make WebGL with Development flag without the following error (but can without Dev flag)

EDIT :
So the only way we were able to get a Development WebGL build to succeed was to switch back to asm linker (in player settings), and in build settings -> check use prebuilt engine (and dev flag). I also updated to 2018.2.5 and tested but had to use this same approach as well.

 

A bit late here but I found out what the issue was for me.The issue was that I had references (that was not used) in code to deleted .jslib files. After removing the references I can make a developer build just fine.

Note that this happens not on the first build run. First couple of dev builds are built completely fine. But on the third+ it completely fails miserably.

I wonder if the py scripts are messing up themselves. Maybe clean Unity install will help.


This utterly ridiculous btw, as no code was changed / added during build tests, only options e.g. linker / dev / pre-built engine.

 

Same issue with 2018.3.2f1, same error message.

This happens with dev enabled + pre-built engine disabled. Sometimes dev build builts with pre-build engine enabled.

 

I'd recommend to strip the JavaScript libraries and the import to those functions (just mock them out with static functions instead of dll imports). I have seen similar errors when the C# Method imports does not align with the Javascript code and emscripten fails. However, just a guess.

 

Is there a quick way to find all js libs in the project?

I don't think I have any left. Maybe some third-party plugin adds them.

 

@xVergilx i'd simply search with the Explorer/Finder for *.js and *.jslib files.

And in your IDE search for

Code (csharp):

1.  
2. [DllImport("__Internal")]
3.  

However, obviously not only jslib functions are imported that way. Also check for any *.dll files used but not available on WebGL which are enabled on "all platforms" in and used. In this case I'd actually expect the error to happen way before emscripten runs, but you never know.

 

No .js / .jslib files found. I guess it's native plugin issue, because in our project we're actually using some plugins for the android / ios.

 

Found out what was causing this - it was indeed native plugin "Mobile Native Popups" that was enabled on all platforms.

Jeez, I wish there was a message about such libs. Free asset store plugins are truly evil.

 

@xVergilx happy you were able to solve it!

 

In case you do not find any problem in plugin, please try to delete Library folder.

 

There was the same error, probably a problem in the names of folders with Cyrillic.
In my case, it was necessary to change the folder with the user name, because Unity is located there: C:\Users\Name\AppData\Local\Unity....

 

Had a problem close to this but i used the letter 'ø' in the project name.. changing it to 'o' solved it for me. (Just in case anyone else comes by with similar problem).

 

hey, were you able to fix this issue If yes then please guide how to fix it as i am having a hard time fixing it. plsss...

 

I am also experiencing this issue in 2020.1.0f1

 

I got this problem with 2020.1.0f1 too. The solution of
UlalaTopola helped me, I had non english symbols in path.

 

This issue was happening for me becuase I was trying to overwrite a property with Pointer_stringify and assigning it to the same variable:

Code (CSharp):

1. variable = Pointer_stringify(variable)

 

In my case, I have fixed it by increasing the free space where I stored my WebGL build. I think it wouldn't have enough space to build.

 

Same error, due to an Unity crash while building WebGL.
As mentioned removed every .jslib files from the project then build is back to normal.
Drop them back : error again.
Found out one of .jslib had a syntax error, fixed and build runs fine.
Usually that doesn't crash webGL build then a bit weird.

 

Unity 2019.4.38 similar errors when trying to do a development build. Normal webgl build works ok, but I would like to connect a profiler...
