Building Swift 5.1 - levivic/zEcoTest GitHub Wiki

Building Swift 5.1

The instructions provided below specify the steps to build Swift v5.1 on Linux on IBM Z for

  • Ubuntu (18.04)

General Notes:

  • When following the steps below please use a standard permission user unless otherwise specified.
  • The directories /<source_root>/, /<install_dir>/ will be referred to in these instructions, and these are temporary writable directories anywhere you'd like to place them.

Step 1. Build using script

If you want to build using manual steps, go to STEP 2.

Use the following commands to build Swift 5.1 using the build script. Please make sure you have wget installed.

wget https://github.com/linux-on-ibm-z/scripts/blob/master/Swift/build_swift_51.sh

# Configure Git User Name and Email
export GIT_USER_NAME = <your_git_user_name>
export GIT_USER_EMAIL = <your_git_user_email>

# Build Swift
bash build_swift_51.sh [Provide -t option for executing build with tests]

Step 2. Install the dependencies

  • Ubuntu (18.04)
sudo apt-get update
sudo apt-get install -y git autoconf libtool git cmake ninja-build python \
        python-dev python3-dev uuid-dev libicu-dev \
        icu-devtools libbsd-dev libedit-dev libxml2-dev \
        libsqlite3-dev swig libpython-dev libncurses5-dev \
        pkg-config libcurl4-openssl-dev systemtap-sdt-dev tzdata clang

Step 3. Obtain the source code and apply patches

3.1 Obtain the source code

export SOURCE_ROOT=/<source_root>/
export INSTALL_DIR=/<install_dir>/
mkdir -p $SOURCE_ROOT
cd $SOURCE_ROOT
git clone https://github.com/apple/swift.git
cd swift
git checkout swift-5.1-branch
./utils/update-checkout --clone --scheme swift-5.1-branch

3.2 Apply patches to Swift

You need to configure your git username and email address before picking up any patches.

git config --global user.email "<your_git_user_email>"
git config --global user.name "<your_git_user_name>"

3.3 Apply patches to Swift Foundation

cd ../swift-corelibs-foundation/
git remote add loz https://github.com/linux-on-ibm-z/swift-corelibs-foundation.git
git fetch loz
git cherry-pick 68412be28a843e37e0be2557669d13024443d718

cd ../swiftpm
git fetch
git cherry-pick b8768525da66690622b37ce8ebc034945604154e

Step 4. Build Swift 5.1 and its components

cd $SOURCE_ROOT
env LD_LIBRARY_PATH=$SOURCE_ROOT/build/buildbot_linux/swift-linux-s390x/lib/swift/linux/s390x/:$SOURCE_ROOT/build/buildbot_linux/swift-linux-s390x/libdispatch-prefix/lib/ $SOURCE_ROOT/swift/utils/build-script --preset=buildbot_linux,no_test install_destdir=$INSTALL_DIR installable_package=$INSTALL_DIR/install.tar.gz

Step 5. Run tests for Swift, Swift Foundation and Swift Package Manager (Optional)

cd $SOURCE_ROOT
cp -r ./build/buildbot_linux/swift-linux-s390x/lib/swift/linux/s390x/* build/buildbot_linux/swift-linux-s390x/lib/swift/linux/
cp -r ./build/buildbot_linux/swift-linux-s390x/libdispatch-prefix/lib/* build/buildbot_linux/swift-linux-s390x/lib/swift/linux/
env LD_LIBRARY_PATH=$INSTALL_DIR/usr/lib/swift/linux $SOURCE_ROOT/swift/utils/build-script --assertions --no-swift-stdlib-assertions --swift-enable-ast-verifier=0 '--swift-install-components=autolink-driver;compiler;clang-resource-dir-symlink;stdlib;swift-remote-mirror;sdk-overlay;parser-lib;toolchain-tools;license;sourcekit-inproc' '--llvm-install-components=llvm-cov;llvm-profdata;IndexStore;clang;clang-headers;compiler-rt;clangd' --llbuild --swiftpm --xctest --libicu --libcxx --build-ninja --install-swift --install-lldb --install-llbuild --install-swiftpm --install-xctest --install-libicu --install-prefix=/usr --install-libcxx --install-sourcekit-lsp --build-swift-static-stdlib --build-swift-static-sdk-overlay --build-swift-stdlib-unittest-extra --test-installable-package --install-destdir=/home/ubuntu/swift-5.1/swift-install --installable-package=/home/ubuntu/swift-5.1/swift-install/install.tar.gz --build-subdir=buildbot_linux --lldb --release --test --validation-test --long-test --stress-test --test-optimized --foundation --libdispatch --indexstore-db --sourcekit-lsp '--lit-args=-v --time-tests' --lldb-test-swift-only --install-foundation --install-libdispatch --reconfigure --skip-test-cmark --skip-test-lldb --skip-test-llbuild --skip-test-xctest --skip-test-libdispatch --skip-test-playgroundsupport --skip-test-libicu --skip-test-indexstore-db --skip-test-sourcekit-lsp

Step 6. Verify installation

$INSTALL_DIR/usr/bin/swift --version

You should see the following output:

Swift version 5.1-dev (LLVM <***>, Swift <***>)
Target: s390x-ibm-linux
