Krom is linked against Glibc 2.36. Ubuntu 22.04 LTS comes with Glibc 2.35

[vmitro]

Not a bug per se, but nevertheless annoying.

Description
The newest Armory SDK (2023.12) comes with the Krom player linked against Glibc 2.36. This makes it impossible to run on a Ubuntu 22.04 LTS which comes with Glibc 2.35. The error:

P.S. I successfully built the Krom player from the armocore repo, although it needed a few -dev packages I was missing on my system. I have renamed the output binary in ./Deployment directory, Armory, to Krom and replaced the one in Armory SDK. The latest commit built fails with the following error:

Using OpenGL version 4.6 (forward-compatible).

and the one suggested by @MoritzBrueckner in armocore issue #71 (91203c36994a770de878aa234aec7f52f46aff1a):

Using LD_PRELOAD trick on a compiled glibc somewhere in /opt/ could work, but the amount of libs needed to manually list is ridiculously large. Chrooting Armory with a custom glibc could also work, but also too much hassle. I don't feel comfortable at just installing this compiled version over the system one. Distro upgrade is also not really an option.

tl;dr: which armorcore commit should one build in order to have a Krom that links against one's system glibc?

Hi, I sadly can't help you with glibc, but I believe the last working version for Armory is armory3d/armorcore@93b696f (at least it still works for me). In the linked issue, I didn't used "apply" to say "check out the repository at this commit", but rather to say "apply the changes from this commit (only) on top of your current repository state". Sorry about the misunderstanding :)

Hey, at the https://github.com/armory3d/armorcore/tree/armsdk branch:

• Krom.createFragmentShader is not a function is resolved
• Not enough memory on image.c Buffer is resolved
• Still need to look into Krom.setAudioCallback is not a function

It is also stripped out of stuff that is not needed for Armory so it should be a little cleaner.

@vmitro
On debian 12 you can add this to your sources.list
deb https://deb.debian.org/debian experimental main
Then do apt -t experimental install libc6
It will work
