My Town

This Open source project won't be updated until Kremlin will stop war in Ukraine and repair damages made in towns: Irpin, Bucha, Gostomel. If this won't happen during next 6 months (until 1 September 2022), then this project will be removed from public space.

Requirements

• macOS 12
• Xcode 13
• Android Studio 2020.3.1
• Android NDK (See version number in file NDK_VERSION in the root of this repository)
• Node 14.17.3 (node -v). Newer versions may also work, but not tested.
• CMake 3.21.2 (cmake --version)
• Ninja 1.10.2 (ninja --version)
• autoconf 2.71 (autoconf --version)
• aclocal 1.16.4 (aclocal --version)
• glibtool 2.4.6 (glibtool --version)
• pkg-config 0.29.2 (pkg-config --version)

Important

• Toolchain build may fail if macOS headers installed under /usr/include. This usually happens if you previously installed package /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg. See details in Xcode Command Line Tools notes. See following SuperUser question about how to uninstall package.
• Toolchain build may fail if the command line tools are present in /Library/Developer/CommandLineTools. Remove them if you are not using them. See: macos - How do I uninstall the command line tools for Xcode? - Ask Different

Keep tools like CMake and ninja up to date.

Using pre-built toolchain

Build of complete toolchain takes ~1.5h. Instead of building it you can just download and use already pre-built package from Releases page.

Setup and Build

1. Install CMake, Ninja, Autotools and git-lfs. Check that all requirements are installed.

   brew install cmake ninja autoconf automake libtool pkg-config git-lfs
   which cmake
   which ninja
   which autoconf
   which aclocal
   which glibtool
   which pkg-config
   which git-lfs

2. Make sure that Xcode Build Tools properly configured.

   xcode-select --print-path

3. Clone this repository.

   git clone https://github.com/vgorloff/swift-everywhere-toolchain.git
   cd swift-everywhere-toolchain

4. Create a symbolic link to NDK installation directory.

   sudo mkdir -p /usr/local/ndk
   sudo ln -vsi ~/Library/Android/sdk/ndk/$VERSION /usr/local/ndk/$VERSION

   The placeholder $VERSION needs to be replaced with a version mentioned in file NDK_VERSION at the root of cloned repository.

5. Start a build.

   node main.js

6. Once the build completed, toolchain will be saved to folder ToolChain/swift-android-toolchain and compressed into archive ToolChain/swift-android-toolchain.tar.gz.

Usage

Please refer file Assets/Readme.md to see how to compile Swift files or build Swift packages using Toolchain.

Sample Projects

Sample projects can be found in a separate swift-everywhere-samples repository. Please look into Readme.md in that repository to get information about how to configure and build sample projects.
