[Inquiry] Java binding doesn't support alpine OS

[adsouz-icims]

Inquiry

Seems like vlakey-glide does not support Alpine Linux.

I tried to use valkey-glide:osx-arch_64:2.0.0-rc3 (using the maven config) in my java spring boot application on my local mac computer. It works fine when I run the application standalone and have it connect to a local valkey engine running in docker. If I make a docker image of my application and run it in a local docker container, I get this error:
Caused by: java.lang.UnsatisfiedLinkError: /tmp/nativeutils1136740648544752/libglide_rs.so: Error loading shared library ld-linux-x86-64.so.2: No such file or directory (needed by /tmp/nativeutils1136740648544752/libglide_rs.so)

I worked around that by adding RUN apk add libc6-compat to my Dockerfile. But that produced another error, Caused by: java.lang.UnsatisfiedLinkError: 'java.lang.String glide.ffi.resolvers.SocketListenerResolver.startSocketListener()' I have gcc installed on my computer.

When I run the application in a docker container in AWS running Alpine Linux, I get this error java.lang.UnsatisfiedLinkError: /tmp/nativeutils1134542456606439/libglide_rs.so: Error relocating /tmp/nativeutils1134542456606439/libglide_rs.so: gnu_get_libc_version: symbol not found

Looks like the valkey-glide jar is compiled against the GNU C Library (glibc) while Alpine Linux uses a different C library - musl libc.

Is there a solution to this issue?

@adsouz-icims Hi, thanks for the issue
@Yury-Fridlyand did we released for alpine?

[Yury-Fridlyand]

no

[avifenesh]

@Yury-Fridlyand Do we have a technical reason not to, now with the cross?

I worked around that by adding RUN apk add libc6-compat to my Dockerfile. But that produced another error, Caused by: java.lang.UnsatisfiedLinkError: 'java.lang.String glide.ffi.resolvers.SocketListenerResolver.startSocketListener()' I have gcc installed on my computer.

Hey @adsouz-icims, can you share the full error you received here?

[adsouz-icims]

@barshaul Here it is:

@barshaul Here is the other one trying to run the application in a docker container locally on my mac:

@adsouz-icims currently, as the conversation mentioned, alpine is not supported for glide java.
Checking the error messages, the first is throwing on this reason. The second error you get locally seems to try to use the mac version inside the docker.

Is using alpine a hard requirement?

[adsouz-icims]

Unfortunately using alpine is a hard requirement. Thanks for looking.
