Re: New J.A Compiles
A small addendum. I also noticed that “make arch=android” seems to work with the original makefile of PlentyChess (without changing the source code). A profile build did not work under Termux with the original makefile.

Re: New J.A Compiles
Can you compile Obsidian 16.15 for Android? The latest compiled version of Obsidian for Android is 16.0.0, but 16.15 is significantly more powerful.Archimedes wrote: ↑Wed Nov 05, 2025 4:13 pm A small addendum.

Thank you for your work.

Re: New J.A Compiles
We should communicate this in a separate thread. Obsidian does not natively support arm64-v8a. For this reason, you are forced to use the SIMDe headers. However, the source code is incompatible with the SIMDe headers in at least two places. I have modified these accordingly so that compilation is possible. You always have to consider the cost-benefit factor and be careful not to get lost in the deep blue ocean.SlonoSlonar wrote: ↑Wed Nov 05, 2025 7:07 pm Can you compile Obsidian 16.15 for Android?

Thank you for your work.

Re: New J.A Compiles
Hi, Jim, when you have a chance, could you please compile the latest Reckless pre-release? They do not have .bmi2 option unfortunately.
