[dbuske]

How does one compile Stockfish on an android phone with Termux.
How does one then find the created compile for android on the phone and copy to a directory where it can be used in a gui?

How does one compile Stockfish on an android phone with Termux.

The same way you would do it under any Linux.
You may have to install make, a compiler and a few tools:

Code: Select all

pkg install make
pkg install clang
pkg install wget

etc.
then If you have a not too old phone, type

Code: Select all

make -j profile-build ARCH=armv8-dotprod

If you get

Code: Select all

error unsupported argument 'armv7-a' to option '-march=' 

just remove the line 678 of the Makefile that looks like

Code: Select all

CXXFLAGS += -fno-gcse -mthumb -march=armv7-a -mfloat-abi=softfp

and retry.
Note that the first compilation is slow because it needs to download the nnue file.
