Compiling android-arm64 for MAME encounters errors, seeking help!

[wolffy1998]

Compilation environment:

Windows 10
MSYS2 provided by the MAME official website
NDK-rc28
SDL-2.32.10

Environment variable configuration:

export SDL_INSTALL_ROOT=/vendor/sdl
export ANDROID_NDK_HOME=/vendor/android-ndk

Compilation command:

make -j5 android-arm64 STRIP_SYMBOLS=1 REGENIE=1

SDL has been compiled for the arm64 version using NDK. sdl2-config and libSDL2.so were placed in the SDL_INSTALL_ROOT/bin and SDL_INSTALL_ROOT/lib directories respectively, and the .h files were placed in the SDL_INSTALL_ROOT/include/SDL2 directory.

After entering msys2 from mingw64.exe and configuring the environment variables, executing the make command reports the following errors:

It seems that the Windows path of the sdl2-config file is being treated as an executable command. I'm not sure what caused this.

Is there an issue with the sdl2-config script?

You cut the part where the error happens, it's before that. If you retry make without clean you should quickly reach it again though.

I had issues compiling mame for android a while back but used the site here https://wiki.mamedev.org/index.php/Android that should get you going just check the genie scripts for the latest platform as linking can change depending what version your using and they may need updated if using a newer platform number. It looks like its defaulting to platform 24 still just make sure your using a nkd/sdk version that links with the same libs if your experiencing issues.

我之前编译 Android 版 MAME 遇到过问题，但用了这里的网站 https://wiki.mamedev.org/index.php/Android 应该能帮你上手。只要查看最新版本的 Genie 脚本，链接可能会根据你使用的版本而变化，如果使用较新的平台号，可能需要更新。看起来默认还是用24平台，只要确保你用的是能链接到相同库的nkd/SDK版本，如果遇到问题的话。

I have compiled the Android-arm64 version of the .so file, and currently encountered an issue when compiling MAME4droid while replacing the osd files.
