Shall be possible, for now just miss some header in android build tool

Code: Select all

util.cpp:26:14: fatal error: 'wordexp.h' file not found
    #include <wordexp.h>

I'll get back with it soon

GREAT!!!

I love Rodent IV because you can chose diffent personalities and create new personalities!!!

Thanks for your help!

Try it and tell me !

For what it's worth cross platform build for android are quite easy for most engine

1°) download the NDK (https://developer.android.com/ndk/downloads)

2°) install it

Code: Select all

$NDK/build/tools/make_standalone_toolchain.py --arch arm --api 21 --install-dir ./my_android

3°) if your ndk is recent enough it will say

Code: Select all

WARNING:__main__:make_standalone_toolchain.py is no longer necessary. The
$NDK/toolchains/llvm/prebuilt/linux-x86_64/bin directory contains target-specific scripts that perform
the same task. For example, instead of:

    $ python $NDK/build/tools/make_standalone_toolchain.py \
        --arch arm --api 21 --install-dir toolchain
    $ toolchain/bin/clang++ src.cpp

Instead use:

    $ $NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/armv7a-linux-androideabi21-clang++ src.cpp

4°) use it ! For RodentIV, I did a little script

Code: Select all

#!/bin/bash

exe=rodentIV_android
echo "Building $exe"
OPT="-s -Wall -Wno-char-subscripts -Wno-reorder -DNDEBUG -O3 -flto -std=c++14"
./android/bin/aarch64-linux-android21-clang++ $OPT *.cpp -o $exe

5°) One thing was missing in that case

Code: Select all

util.cpp:26:14: fatal error: 'wordexp.h' file not found
    #include <wordexp.h>

so, being lazy, I just make function ChDirEnv always return false ! Thus be warned that personalities can not be set by environment variables.

Code: Select all

    FILE *personalityFile = NULL;
    if (isabsolute(fileName)                    // if known locations don't exist we want to load only from absolute paths
        || ChDirEnv("RIIIPERSONALITIES")        // try `RIIIPERSONALITIES` env var first (26/08/17: linux only)
            || ChDir(_PERSONALITIESPATH))       // next built-in path
                personalityFile = fopen(fileName, "r");

Hi,
I always use the gui "chess for android" from Aart Bik.

With Rodent III I was able to chose the personality files.

Unfortunately I can not run/install the software you linked above.
I do not undertand this stuff - I am just an old chessplayer.

But I thank you very much my friend for trying!!!

Greetings from Austria
Peter

What is your android version?

Did you download the dropbox link? No need to understand the whole post.

Thank you

but I can't load this engine in DroidFish on Galaxy S7 with Android 7. Perhaps it's for newer versions.

Used api level 21 so should work more or less everywhere. Seems find on my a40 with android 9.
