Build
cargo buildCross Compilation
Arm64 Linux
Download the linux toolchain from Arm GNU Toolchain Downloads.
Set the env variable ARM64_TOOLCHAIN to the path of the toolchain directory.
Create a toolchain symbolic link using the following command in Unix:
ln -s $ARM64_TOOLCHAIN aarch64-linux-gnu... and the following command in Windows (cmd vs powershell):
mklink /D aarch64-linux-gnu %ARM64_TOOLCHAIN%
New-Item -ItemType SymbolicLink -Path aarch64-linux-gnu -Target $env:ARM64_TOOLCHAINTo install the Rust targets for Arm64 Linux using rustup run:
rustup target add aarch64-unknown-linux-gnuThen you're ready to build Boytacean's libretro core:
cargo build --target=aarch64-unknown-linux-gnu --releaseAndroid
Configure NDK_HOME environment variable to point to your Android NDK directory and then create local toolchain replicas in the root project directory using:
mkdir -p ndk
${NDK_HOME}/build/tools/make_standalone_toolchain.py --api 26 --arch arm64 --install-dir ndk/arm64
${NDK_HOME}/build/tools/make_standalone_toolchain.py --api 26 --arch arm --install-dir ndk/arm
${NDK_HOME}/build/tools/make_standalone_toolchain.py --api 26 --arch x86 --install-dir ndk/x86To install the Rust targets for Android using rustup run:
rustup target add aarch64-linux-android
rustup target add armv7-linux-androideabi
rustup target add i686-linux-androidThen you're ready to build Boytacean's libretro core using the following commands (for release builds):
cargo build --target=aarch64-linux-android --release
cargo build --target=armv7-linux-androideabi --release
cargo build --target=i686-linux-android --releaseRun
Mac OS
cargo build --release
cp -p ../../target/release/libboytacean_libretro.dylib ~/Library/Application\ Support/RetroArch/cores/boytacean_libretro.dylib
cp -p res/boytacean_libretro.info ~/Library/Application\ Support/RetroArch/info/boytacean_libretro.infoThen you should be able to see the Core available in RetroArch.
If there's a new for debugging information to be display in RetroArch console then use:
export RUST_BACKTRACE=1
cargo build --features debug
cp -p ../../target/debug/libboytacean_libretro.dylib ~/Library/Application\ Support/RetroArch/cores/boytacean_libretro.dylib
