Warning: /lib64/libc.so.6: version `GLIBC_2.14' not found

At my company we are using node-canvas-prebuilt@~2.0.0-alpha.2 to build PNG sprite images. Everything works fine.

Suddenly, on some machines, yarn is reinstalling node-canvas-prebuilt even when dependencies remain unchanged. Don't know why - it's another question.

yarn downloads canvas-prebuilt-v2.0.0-alpha.2-node-v57-linux-x64. This is a correct behavior. But after installation build script is failing with error.

Warning: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by ./node_modules/canvas-prebuilt/canvas/build/Release/canvas.node) Use --force to continue.
# Absolute path was ommited.

I made a backup of correct canvas.node and we are replacing wrong one when issue occurs. After replacement everything works as usual without errors.
Re-installation of node_modules and yarn cache clean doesn't help.

It seems like canvas.node in that tarball was changed after release. At instance, file size differs from the previous one. I don't know if that possible, but this is my only assumption.

Versions of Node, npm and yarn are the same on every development machine.
Node.js version: v8.11.2
yarn version: 1.3.2
npm version: 5.6.0

OS and libc versions are the same too: CentOS 6.9 and GNU libc v2.12.

To summarize, I have two questions:

1. Why canvas.node was changed in archive file of June 2017 release?
2. How to tell yarn to not to re-install installed binary (probably, this question should be asked somewhere else).

Sorry about that!

I did change the alpha builds (never 1.6.x) four times to get broader binary compatibility. I added an "official" glibc version to target in 59f8822. It's a mystery to me how it ever worked for you since before I was building on Ubuntu 12.04, which has glibc 2.14. Maybe at one point I was using a really old distro for the docker image

Anyways, your version of glibc is from 2010 and most distros that have glibc that old are not supported anymore 😕. I don't want to have to compile glibc from source so right now I can only support 2.13 and up since it comes with Debian Wheezy.

That's sad 😞

Thanks for the answer.

[chearon]

Sorry about that. If I find the time maybe I can try building on a CentOS docker image instead of Debian, since it seems to have the oldest libc.

[ilyazub]

I'll try it too. Also, please publish git repository of chearon/canvas-prebuilt docker image, because for now I need to use something like ImageLayers to inspect Dockerfile.

Cool, it's right here. Once you get the build deps, hopefully all the commands beyond that Just Work.
