GLIBC_2.29 not found

Hi,

We use unityci/editor:2019.4.21f1-base-0.10 in our automated test CI and we got this error :

Plugins: Couldn't open XXX/Library/PackageCache/com.atteneder.draco@1.4.0/Runtime/Plugins/x86_64/libdracodec_unity.so,
error: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by XXX/Library/PackageCache/com.atteneder.draco@1.4.0/Runtime/Plugins/x86_64/libdracodec_unity.so)

The docker image is based on 18.04.5 LTS (Bionic Beaver) which contain GLIBC 2.27.

Could it be possible to build libdracodec_unity.so with GLIBC 2.27 ?

Hi @Blocovin,

Thanks for the detailed report! I built the library via GitHub actions' virtual environment ubuntu-20.04. I started an attempt to build with ubuntu-18.04. If you want to, go ahead and test the library. You should be able to download the artifacts here:

https://github.com/atteneder/draco/actions/runs/625090681

Let me know if it works.

Thank you for your solution !

I hadn't seen your draco repository with GitHub actions 😆

I tried to move com.atteneder.draco@1.4.0 from unity package cache into Assets folder and replaced libdracodec_unity.so by .so contains in github actions result.
And I DRACO_UNITY in Scripting Define Symbolsbut I got error :

I think I'm doing something wrong ?

For more information, we use latest unity LTS for our production app (2019.4.21f1 LTS).
Officially supported ubuntu version for Unity 2019.4.21f1 LTS is is still 18.04.
Ubuntu 20 is officially supported by Unity 2020.2.

Discussion about it from game-ci.

Oh sorry. Those libs are meant for version 2.0.0-preview :/
I have to build the current branch (legacy/unity-1) as well with ubuntu 18.04

[ketourneau]

Thank you very much !
I fork and I build legacy branch legacy/unity-1.
So now our test CI work perfecty with draco ❤️
