"Please port CPU detection to your platform" Error with M1 Chip

Trying to run OSM2World on an M1 mac results in this error:

I did some research, and it seems to be an issue with GlueGen being an old version (2.0.2). According to this report, it's fixed in GlueGen 2.3.1-1 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=791993

tried just building with a newer version of gluegen, but unfortunately it needs some extra work

Thanks for testing, this is good information as I don't have access to M1 hardware

Upgrading to JOGL 2.4.0 (and the associated gluegen) is something I want to do for other reasons, such as compatibility with modern Java versions. The main challenges are that there's no nicely packaged build of 2.4.0 in the usual maven repositories (so I'll likely end up having to bundle a build with my code), and that upgrading across multiple version jumps does involve significant changes to OSM2World's OpenGL-related code.

I've found this if it's any good :)

https://mvnrepository.com/artifact/org.jogamp.jogl/jogl-all-main/2.4.0

Thanks, this turned out to be an excellent hint. I was able to use that repository to upgrade to 2.4.0 by using it as a dependency as described here.

So as of fbe6b37, OSM2World is now using a JOGL 2.4.0 release candidate. Hopefully this takes care of M1 support?

After installing an M1-native Java8 (https://stackoverflow.com/a/73843488/13351126), it works! thank you so much 😄

The error you get when using java8 through Rosetta, for posterity (expand me)
