Hi wdh, I found this:
https://stackoverflow.com/questions/142 ... ontrollers

[wdh]

It's finding the libgdx library ok, the problem looks to be the missing symbol "__objc_empty_cache".

I found a similar issue in an unrelated project, affecting the same MacOS version - see https://forum.lazarus.freepascal.org/in ... 9.msg.html - this suggests a tweak to the compile options may be required:

On macOS versions before 10.14, that symbol is in libobjc rather than in CoreFoundation.

Perhaps this is really an issue for the libgdx maintainers, but the thread has the details for what was done to resolve it in the other project.

Is there any way to tell ysoccer not to load libgdx at startup, or to load an older version?

Unfortunately I don't have a Mac, and I cannot replicate the bug.
But the source code is fully available. If another developer can find a fix, I can add it.
Libgdx is necessary for the game.

I did try to build it myself and while it seemed to succeed, I ended up without a "ysoccer" executable. Not familiar with gradle etc to I don't really know what I'm looking at - if you could share any notes on what you do to build the various versions it would be great

In the meantime, I confirm that updating to MacOS Mojave (10.14.6) resolves the issue. It would be worth adding a note to the download page to mention that anyone on MacOS will probably require at least Mojave to run the game.

Thanks

Thanks for the info, I will add the note.

Regarding building from source, this page may be of help:

I meant notes on how you guys build ysoccer, not libgdx - sorry if I did not make that clear.

Just running ./gradlew build worked, but left me without a ysoccer or ysoccer.jar so there must be something I've missed.
