sync server v25.02 can not be build static on armv7 anymore

[LuckyTurtleDev]

The anki sync server can not be build static on armv7 anymore, since release 25.02.
I get the error message that library not found: dl.
This error does not occur on armv8 or amd64.

Build the following docker image for armv7 with docker build --platform linux/arm/v7 --build-arg version=25.02 . .
https://github.com/LuckyTurtleDev/docker-images/blob/862887d9fb58f06c40c360e7a93ace74256ce813/dockerfiles/anki/Dockerfile

• docker build --platform linux/arm/v7 --build-arg version=24.11 . works
• docker build --platform linux/arm/v7 --build-arg version=25.02 . fail
• docker build --platform linux/arm64/v8 --build-arg version=25.02 . works
• docker build --platform linux/amd64 --build-arg version=25.02 . works

@mikehardy AnkiDroid still targets arm7, right? If it's still working there, perhaps this is just an issue with the docker environment.

Hey @dae - can't say whether anyone has actually tested this and sees it running still by loading up the APK and using it, or whether we build all the things required to say syncserver is working or not but yes, we do generate an armeabi-v7a artifact still:

backend build with target list, includes armeabi-v7a

Our built artifacts on front-end, consuming that library:
