I'm getting this error : unable to load JNA native support library, native methods will be disabled. java.lang.UnsatisfiedLinkError: /data/data/com.termux/files/home/.cache/JNA/temp /jna10838117941975478408.tmp: dlopen failed: library "libc.so.6" not found at jdk.internal.loader.NativeLibraries.load(Native Method) ~[?:?] at jdk.internal.loader.NativeLibraries$NativeLibraryImpl.open(NativeLibr aries.java:384) ~[?:?] at jdk.internal.loader.NativeLibraries.loadLibrary(NativeLibraries.java:

Yeah, that is because the bundled native libraries are built for GNU/Linux, not for Android. We have to build them ourselves, just like the libjansi case.

Sorry to interrupt, but I ran into a similar JNA UnsatisfiedLinkError error when tried running Neo4j on Termux with OpenJDK 11 built by \@Lzhiyong. Things are the same after I tried building Neo4j on Termux with OpenJDK 11 mentioned above.

Does this mean I need to manually patch Neo4j's code and rebuild it? Or would you mind shedding light on what I should probably do?

Can this be available ?

[TomJo2000]

There may be licensing concerns regarding elasticsearch's licensing model. It is unclear from my research into the topic if either:

• The Elastic License 2.0 (ELv2) - Which the binary distribution is licensed under.

Or

• The Server Side Public License (SSPL) - Which the Source Code is licensed under.

Are GPL compatible.

[pmg1991]

In Elastic License 2.0 license , we can't host the Elasticsearch as running service and disable license key functionality . so there is no problem if we don't that.

https://www.elastic.co/pricing/faq/licensing#what-kind-of-use-constitutes-“offering-the-product-as-a-service”-under-sspl

`To be clear, our distributions starting with 7.11 will be provided only under the Elastic License 2.0, which does not have any copyleft aspects and allows free use, modification, and redistribution, with only 3 simple limitations to protect our products and brand, as outlined above.

If you are building Elasticsearch and/or Kibana from source, you may choose between SSPL and the Elastic License to govern your use of the source code. The clause in question only applies if you build from source, choose SSPL as your governing license, and you are providing Elasticsearch and Kibana as a paid service to others. In this case, it applies only if you are “providing Elasticsearch and Kibana as a Managed Service” as the primary offering, or a major part of it.`

@licy183 is this package possible?

[TomJo2000]

Due to licensing issues, no not in this repo. Elasticsearch uses a "source available" licensing model under either the SSPL-1.0 or Elastic License 2.0. Neither of which is a free software license under Open Source Initiative (OSI) criteria, and neither is currently accepted for main repo packages on Termux.

Elasticsearch could still be packaged in the Termux User Repository. https://github.com/termux-user-repository/tur

[sylirre]

OpenSearch can be packaged instead: https://github.com/opensearch-project/OpenSearch

SSPL and everything that forbids particular usage type is a no-go.
