h3-java: Failure on MacBook M1

v3.7.2 should now be released to Maven Central which should include the darwin-arm64 binary!

@g-derzhavets

Does this mean I can not run v3.7.2 on Ubuntu 16.04?

I believe this is the same issue as #85 and #88. While I can take a look at pinning dockcross to a far back enough version, Ubuntu 16.04 is out of standard support so I would suggest upgrading to the latest LTS if possible.

I am also on M1 mac with Monterey macOs. I have a gradle project, that uses the com.uber:h3:3.4.1 lib. I’ve managed to build the libs locally via mvn clean install -Dh3.use.docker=false and I see that the new libs (3.7.2) were copied into my .m2 repository. I am not that proficient with dependencies, so would you be able to explain, where should I put these jars so my gradle project in Intellij could use them? @isaacbrodsky thanks

upd: I managed to make gradle (with this recommendation) to use the lib from my .m2 and my build ran successfully. Thanks a lot @muthenberg for raising the issue and @isaacbrodsky for fixing it 😃

I hope the lib for arm will be soon published to the maven repository.

@muthenberg Would you be able to upload a complete build log to Gist?

I think the issue you are running into may be due to the Docker cross compiling failing (it needs to use a JNI header from the host platform.) Please try instead mvn clean install -Dh3.use.docker=false

Could you also post the output of uname -sm? The file build-h3.sh may need to be updated to put the library in the right place. Probably something like adding:

   "Darwin arm64") LIBRARY_DIR=darwin-arm64 ;;

(There’s also the possibility that H3CoreLoader.java will need a small update to detect the right library to load. If that’s the case you should be able to use H3Core.newInstance(H3CoreLoader.OperatingSystem.DARWIN, "arm64") as a workaround.)

BTW.: If I try to build the newest version (commit #661bea1) with mvn clean install I get:

It seems that the system tries to build H3 for Linux ARM64, which will obviously not work. Unfortunately my Make knowledge is not great enough to fix that issue.
