symbol lookup error on nVidia

[bryanlarsen]

node-gl was working fine for me inside Vagrant, then I tried speeding it up by using it on a machine with a real X server on an nVidia card and I got this error:

node: symbol lookup error: .../node_modules/gl/build/Release/webgl.node: undefined symbol: _Z15XextFindDisplayP15_XExtensionInfoP9_XDisplay

I fixed the error by recompiling everything and manually copying webgl.node into my installation.

Seems like a problem with the prebuilt binaries linking statically against some X server configuration. Maybe the right solution would be to have the prebuild check if the module fails to load and in such an event rebuild the module from source.

@ralphtheninja do you know if there is a way to configure prebuild to do something like this?

Hello! I think I'm having the exact same problem with headless-gl, but I'm a bit of a beginner and I'm not quite sure I understand you fix.

Can you please detail a bit what you did to make it work, I would appreciate it greatly. Thank you for reading. :)

[NHQ]

me too, details plz

[ralphtheninja]

@mikolalysenko Might be hard to check this, since it might load on the machine building the binaries but not on another machine.

You could use https://github.com/juliangruber/require-rebuild to have it be rebuilt on the target machine if the require fails

require-rebuild didn't work for me, but it's a pretty rad hack!

Here's what worked for me in more detail:

1. Set up the system dependencies sudo apt-get install -y build-essential libxi-dev libglu1-mesa-dev libglew-dev (That was for Ubuntu, see https://github.com/stackgl/headless-gl#system-dependencies)
2. Set up the dev environment, i.e. follow steps 1-6 of https://github.com/stackgl/headless-gl#how-should-i-set-up-a-development-environment-for-headless-gl (Note for step 6 I had to do npm run rebuild instead of npm run build)
3. Copy and replace the built webgl.node file into your node module, e.g. cp headless-gl/build/Release/webgl.node node_modules/gl/build/Release/webgl.node

hi, @tehbelinda
I followed your instruction, however got stuck in the step 3: cp headless-gl/build/Release/webgl.node node_modules/gl/build/Release/webgl.node
I did not find the folder node_modules/gl/build/Release/webgl.node under the minos root. And I also checked no node_modules folder in the src code.
Do you created it or is it under other path?

[tehbelinda]

Hi @nina124 this would be where ever you ran npm install to set up the node modules originally. I'm guessing you are here from the 2 issues linked above, so looking at those, it seems like the part that's run in node is in the minos/server path so try looking in there? If not, then you might want to try checking with minos if there's something wrong with the npm setup

[nina124]

Thanks @tehbelinda
Problem solved!

Closing as part of clean up. Feel free to re-open this issue.

[fcard]

I have gotten this problem and recompiling from the source did not solve it.
npm test also fails at this point:

✓ limits_gl-max-texture-dimensions55Aborted (core dumped)
not ok 5838 no plan found
⨯ fail 1

So it might be something specific to my pc hardware/configuration, if that's not supposed to happen? Should I open another issue?

My OS is Linux/Ubuntu Mate (Ubuntu 20.04, with kernel 5.4.0-42), architecture is Amd64.

I had the same issue, and solved it using npm rebuild --build-from-source gl

[trusktr]

An alternative is the webgl-raub package, which worked out of the box without --build-from-source for me.

[entrptaher]

I solved this with this package.json example.

{
  "name": "video-generation",
  "version": "1.0.0",
  "main": "index.js",
  "license": "MIT",
  "dependencies": {
    "editly": "^0.14.2"
  },
  "overrides": {
    "editly": {
      "gl": "https://github.com/stackgl/headless-gl.git"
    }
  }
}

And then,

cd node_modules/gl && yarn rebuild

It was not working for me otherwise.
