Missing static JDK libraries compiled against musl

[spockz]

Describe the issue
I am trying to make a static image which, as per instructions, needs musl as the libc implementation. When doing this native-image fails, unable to find the static jdk libraries it needs in $JAVA_HOME/lib/static/linux-aarch64/musl. This directory is missing, only a glibc directory exists.

Steps to reproduce the issue
Please include both build steps as well as run steps

1. **native-image -cp --verbose -H:+PrintClassInitialization --trace-class-initialization=io.netty.buffer,io.netty.handler.ssl --trace-class-initialization=io.netty.buffer.ByteBufUtil --trace-class-initialization=io.netty.handler.ssl.ReferenceCountedOpenSslContext --trace-object-instantiation=io.netty.handler.ssl.ReferenceCountedOpenSslContext -H:Optimize=3 --initialize-at-build-time=org.slf4j --initialize-at-build-time=ch.qos.logback --enable-https --enable-http --static --libc=musl --target=linux-aarch64 --native-compiler-path=/home/alessandro/Downloads/aarch64-linux-musl-cross/bin/aarch64-linux-musl-gcc -H:Name=sidecar

It appears the files are taken from the JVMCI builds, https://github.com/graalvm/labs-openjdk-11/. Should this issue be moved there?

[oubidar-Abderrahim]

I believe if you're cross-compiling, you'll need to install musl toolchain for aarch64 in your $TOOLCHAIN_DIR (as explained in https://www.graalvm.org/22.1/reference-manual/native-image/StaticImages/)

[spockz]

@oubidar-Abderrahim yes, I did. However, that toolchain itself is generic. It doesn't contain the JDK-static libraries compiled against musl, those are only available for linux-amd64 in that download.

I have the same issue for 22.3.r17

We shall have a buildpack for this which can be used together with spring-boot-maven-plugin

The issue is with nik
sdk use java 22.3.r17-nik ->does NOT work
sdk use java 22.3.r17-grl ->woks

[cforce]

Any news here .. when this will be fixed

[petermz]

The NIK issue has been fixed in 22.3.1. The original issue, I'm not sure. The instructions mentioned there imply that static linking against musl is not supported on ARM.

[cforce]

Any builder image used in packets buildpack https://github.com/paketo-buildpacks/native-image is to recent in context of libc Version requirement that it simply can not be successful executed on aws lambda due to bindings to libc version not matched on lambda base images(to old) aws/aws-lambda-base-images#59 (comment)

How shall build and deploy to lambda using bionic /glibc 2.7
