Unable to compile on macOS ARM64

[lokka30]

Hi, I am unable to compile voxel-game on macOS ARM64 (M1 MacBook Air):

I tried to solve this myself by adding a macOS ARM64 profile for LWJGL but that was fruitless as I have no idea what I was doing there.

[SnkSynthesis]

Hi @lokka30

I've added support for macOS ARM64 in pom.xml However, I have not tested it.

[lokka30]

Sweet! I'll test it now.

[lokka30]

Unfortunately I still can't compile (following instructions on the README):

Which JDK are you using?

[lokka30]

Which JDK are you using?

lach@LAIR ~ % java -version
openjdk version "17.0.1" 2021-10-19
OpenJDK Runtime Environment (build 17.0.1+12-39)
OpenJDK 64-Bit Server VM (build 17.0.1+12-39, mixed mode, sharing)

:)

[SnkSynthesis]

Okay :). I've updated pom.xml to include versions of all LWJGL dependencies.

[lokka30]

Ooh, working better now! Encountered a new warning/error:

[SnkSynthesis]

Okay that's better. Based on https://www.lwjgl.org/guide, MacOS users have to add the option: -XstartOnFirstThread. I've updated the README.md to include that.

[lokka30]

Another step closer! But now a new error. 😣

[lokka30]

I would also like to add - on macOS we need to skip the ./mvnw compile exec:java step as afaik we can't parse JVM arguments into that command. I used ./mvnw clean package and java -Xstart... -jar ... to compile and run it.

[SnkSynthesis]

Good point, thanks, I've updated the README to include that. I got the same error on Windows. It looks like that loading textures wasn't working with the compiled JAR file. I've fixed it (tested on Windows).

[lokka30]

Thanks! Another step forward :)

Would you like me to PR an improvement to the README for Linux/Mac users? - the two platforms seem to have different enough instructions I think they should be separate

[SnkSynthesis]

That's better :). I've updated window initialization code to support MacOS. Also, I've updated README to separate Mac and Linux instructions.

[lokka30]

The instructions are perfect! And, it runs!

Although.. not as we hoped. 😆

Low framerate and extreme CPU usage, likely also high memory usage as it became slower over time.

By the way, I have no expectation for you to actually work on this issue! As voxel-game is a really neat open-source project, I took interest in trying to improve it through issue documentation and testing. Especially since this particular issue is taking up a lot of your free time for a project with low demand, and on both unpopular hardware and an upopular operating system, feel free to leave this issue alone if you wish. :) I would contribute to the codebase if I knew anything about Java game development, but unfortunately I am only familiar with the programming language itself and not any of these libraries. As I am a student, finding the time to learn these libraries is also not an option. 😞

[SnkSynthesis]

Hi @lokka30

👍 I've made some changes based on the warning that is showing in your terminal when you run the program ("Warning: Validation Failed: ..."). I hope it works now 😄

[lokka30]

Hi @lokka30

👍 I've made some changes based on the warning that is showing in your terminal when you run the program ("Warning: Validation Failed: ..."). I hope it works now 😄

Hi, unfortunately I still have the same result as last time. Feel free to give up if you want 😆 otherwise I'm happy to continue testing!
