swift-everywhere-toolchain

Requirements

macOS 11.3
Xcode 12.5
Android Studio 4.1.3
Android NDK 21.4.7075529
Node 14.16.1 (node -v). Newer versions may also work, but not tested.
CMake 3.20.2 (cmake --version)
Ninja 1.10.2 (ninja --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

Check that CMake is installed. Install CMake if needed.
```
which cmake
brew install cmake
```
Check that Ninja is installed. Install Ninja if needed.
```
which ninja
brew install ninja
```

Check that Autotools is installed. Install Autotools if needed.

which autoconf
brew install autoconf

which aclocal
brew install automake

which glibtool
brew install libtool

which pkg-config
brew install pkg-config

Check that git-lfs is installed. Install git-lfs if needed.
```
which git-lfs
brew install git-lfs
```
Make sure that Xcode Build Tools properly configured.
```
xcode-select --print-path
```

Clone this repository.

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

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.
Start a build.
```
node main.js
```
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.
