Swift Build Instructions for WALA Integration

You should have completed the steps in Getting Started before continuing. The following lists how I got Swift-WALA integration working on my MacBook Pro; some steps, environment variables, folder structures, etc. may be different for you. This is provided as a reference and example, not as instruction.

My initial state: WALA built and running in Eclipse Neon RCP Working directory in this example is ~/WalaSwift Working WALA build is at ~/WalaSwift/WALA

Machine Profile:

• macOS Sierra 10.13.2
• java: 1.8.0.131 64-bit

The Process

• Update your ~/.bash_profile or /etc/environment:

  # CMake

  PATH="/Applications/CMake.app/Contents/bin:${PATH}"

  export PATH

  # WALA and Swift

  export WALA_HOME=~/WalaSwift/WALA

  export SWIFT_WALA_HOME=~/WalaSwift/swift-wala

• source your updated file

• [Mac] Download Xcode 9.2 (as of 3 Jan 2018; check the Apple Swift Readme to see if the requirement has changed)

• Install Xcode to your /Applications folder. Run Xcode to see if it needs to install additional components.

• [Optional] If you've been using an Xcode Beta build, switch your Xcode environment back to Xcode official

  • sudo xcode-select --switch /Applications/Xcode.app/

• Confirm that you have the correct tools after switching

  • clang --version
    • Note: Xcode 9.2 is using Apple LLVM Version 9.0.0 (clang-900.0.39.2)

• [Ubuntu] Run the big sudo apt-get command from the Apple Swift Readme documentation.

• Create swift-source directory:

  • > mkdir swift-source

• Move into the swift-source directory:

  • > cd swift-source

• Clone the wala branch of the uasys/swift repo:

  • swift-source> git clone -b wala https://github.com/themaplelab/swift/

• Move into the swift directory:

  • cd swift

• Checkout requirements for build:

  • swift> utils/update-checkout --clone

• Confirm you are on the wala branch - it will revert to master during this process.

  • swift> git branch
  • swift> git checkout wala

• Now run the build script with tests:

  • swift> utils/build-script -r
    • Up to 2-hour initial clean build on rMBP i7-4980HQ with 16 GB RAM
    • If integration worked, you should see a ton of "FOO:" and "CAstValue: 3.7" output near the end.

• Success!
