[docs] Electron apps - undefined symbol __cxa_pure_virtual #394

mitchhentges · 2019-02-04T05:39:09Z

Hey, I'm learning how to set up neon here, and I'm running into an issue where, upon launching electron, I get the error: undefined symbol: __cxa_pure_virtual.

FWIW, I followed the documentation here.
I found #194, but I've interpreted it as the ticket for integrating with electron-rebuild, and that the electron-build-env process was already functional? 🤔 😄

To reproduce:

git clone https://github.com/electron/electron-quick-start
cd electron-quick-start
npm i neon-hello
npm i electron-build-env neon-cli --save-dev
$(npm bin)/neon build neon-hello
Edit main.js, adding require('neon-hello') to the top
npm start

$ npm start                                         

> electron-quick-start@1.0.0 start /home/mitch/dev/electron-quick-start
> electron .

App threw an error during load

Does the example work for you?

mitchhentges · 2019-02-04T05:46:25Z

Hmm, I'm able to reproduce the problem in the example, too 🤔

node --version: v11.9.0
npm --version: 6.7.0

(holy that was a fast response! You're crazy 😄)

Hammster · 2019-02-07T08:20:09Z

@mitchhentges the versions for the current electron-quickstart should be the follwing, since you use node 11.9.0 could you try to use node 10.11.0 when building instead.


Electron	4.0.4
Node	10.11.0
Chromium	69.0.3497.106

mitchhentges · 2019-02-11T08:27:51Z

Using nvm, I've installed node@10.11.0, but I'm still able to reproduce the issue.
I didn't need to install Chromium locally to run electron-quick-start.
I did a fresh clone of electron-quick-start - looks like they're still on electron@4.0.3


Electron	4.0.3
Node	10.11.0
Chromium	N/A

Hmm 🤔

Hammster · 2019-02-11T09:14:24Z

@mitchhentges electron comes with a chromium to render the content, no worries. I don't have the time to test the issue currently (currently moving into a new flat) if i find some time at work i will try it though.

Related: neon-bindings/examples#30

MeryllEssig · 2019-03-30T21:18:00Z

If someone is interested, I solved the issue by doing what someone did in this post : https://users.rust-lang.org/t/neon-electron-undefined-symbol-cxa-pure-virtual/21223

#[no_mangle]
pub extern fn __cxa_pure_virtual() {
    loop{};
}

I added this piece of code in my native/src/lib.rs file, rebuilt the project, and it worked for me.

amilajack · 2019-03-30T21:19:19Z

@theJian does neon-bindings/examples#30 resolve this issue?

theJian · 2019-03-31T10:48:19Z

@amilajack It doesn't.
I'm having this issue on Linux machine. The example runs well on mac os though.

theJian · 2019-03-31T10:50:23Z

@mitchhentges It looks like you are using Linux from your screenshot. Have you tested on other platforms?

fominok · 2019-05-11T18:40:07Z

Any updates on this? Cannot run referenced example, but really interested in getting started with electron + neon

fominok · 2019-05-11T21:00:10Z

Well I've tried solution with defining missing fn as suggested by @MeryllEssig but now it has undefined symbols like _ZN12v88Function3.. and so on

stoically · 2019-05-14T09:42:54Z

@fominok Happened to me when I didn't build with electron-build-env - doing so resolves it for me (in combination with the workaround from @MeryllEssig).

kjvalencik · 2019-08-16T19:40:23Z

Duplicate of #409

kjvalencik · 2019-09-08T23:16:45Z

Re-opening this issue. It is not a duplicate. It's caused by a missing .cpp(true) when building neon-runtime. It should be fixed in an upcoming PR to resolve several electron issues.

fominok · 2019-10-30T21:07:47Z

@kjvalencik Hello, is this issue fixed? I've just downloaded examples and trying to start electron-app even with neon-cli dependency bumped to 0.3.3 and still receiving this error

kjvalencik · 2019-10-30T21:43:56Z

Yes, it should be fixed. There is an electron test that can be used as an example. The rust neon crate needed to be bumped as well.

fominok · 2019-10-31T22:16:00Z

@kjvalencik thank you for the fast reply
I've tried to build this example and have failed with 'lib/cli.js' not found error on npm i and different node versions error. I'm new to Node and build steps for this example would be very helpful for me
Had to replace node ../lib/cli.js to neon and everything goes fine, thanks!

adityapk00 · 2019-12-30T01:46:14Z

Hello. I just tried this on Linux (Ubuntu 18.04), and this still fails with the same error.

I'm using the latest neon (0.3.3) and hello-neon v0.1.1

Edit:
Specifically, I'm trying to build this example: https://github.com/neon-bindings/examples/tree/master/electron-app

kjvalencik · 2019-12-30T15:17:55Z

@adityapk00 That's likely an issue in the examples repo (for example, it's using an older cli version). Can you open an issue there? Thanks!

This was needed because of a upstream issue of neon. The issue has since been fixed so no need for it anymore. Upstream issue: neon-bindings/neon#394.
