Hi Aleksei,

I don't like using PM for things that could be of interest for more than one person

Ok got it. I prefer PM because I don't want to look "silly", with my dump questions.. :oops:

but here are some more things I found out:

I also got crashes when using NDK r21d, so I used version r20b instead. I suspect this is related to the -fopenmp flag and I also suspect you only need this flag to run the training code, but I have not tested this.

For recent NDK versions you no longer need to create a standalone toolchain. You can run the compiler directly from the bin directory created when unpacking the NDK zip file, e.g. something like d:\android-ndk-r20b\toolchains\llvm\prebuilt\windows_something\bin. It may still work to create a standalone toolchain though, I have not tested that.

You don't need to change the Makefile when using your bat file because it is invoking the compiler directly so the Makefile is not used.
I've downloaded android-ndk-r20b-windows-x86_64, unzipped it, and rename the folder to "0", so directory is now "D:\Downloads\0".
First i created standalone toolchain, it didn't work, i got this errors.

I think this happens because your script is not compiling all required files. You need to compile all files corresponding to the SRCS variable in the Makefile.

-----------------------------------
I managed to make android version (from nodechip source) using standalone toolchain, and i want to ask you something. Why your compilation is 1.446 KB while mine is 723 KB, also your is faster about 200 nps, did you make it on Linux PC? Or there is another way for engines compiling with NDK's clang?

I used static linking (-static) to make the engine work on more android devices. This makes the compiled file a lot larger though.

The speed difference is probably because I enabled ARM NEON vector instructions (-DIS_ARM). To make this work I had to add an include file to nnue_common.h. For details see:
