A few, very simple, bash scripts to clone, configure and build Swift on ARM devices.
Derived from package-swift by @iachievedit, some patches from swift-arm by @hpux735.
Currently this project builds Swift 3.1 (get it here) but only on Ubuntu Mate 16.04 (see #4), check out the 3.0.2 tag for the previous version, that worked on both Ubuntu 16.04 and Raspbian. SPM will compile correctly only on Ubuntu.
The scripts:
-
clone.sh - Install dependencies and clones the main Swift repository and all the related projects
-
checkoutRelease.sh - Resets all repos, updates them, checks out a specific tag (3.1 at the moment) and apply the patches
-
build.sh - Build
-
clean.sh - Clean all build artifacts
First of all, use a suitably sized sd-card, at least 16Gb in size.
Configure a swap file of at least 2Gb, on Ubuntu:
sudo fallocate -l 2G swapfile
sudo chmod 600 swapfile
sudo mkswap swapfile
sudo swapon swapfile
You'll need to manually enable the swap file with swapon each time you reboot the raspberrypi (or the system will just run without swap).
On Raspbian, open /etc/dphys-swapfile and edit:
CONF_SWAPSIZE=2048
Save the file and:
sudo /etc/init.d/dphys-swapfile stop
sudo /etc/init.d/dphys-swapfile start
Now, call the included scripts as follows:
-
Launch
clone.shthat will install the required dependencies (git cmake ninja-build clang-3.7 python uuid-dev libicu-dev icu-devtools libbsd-dev libedit-dev libxml2-dev libsqlite3-dev swig libpython-dev libncurses5-dev pkg-config libblocksruntime-dev libcurl4-openssl-dev autoconf libtool systemtap-sdt-dev), fix clang links and clone apple/swift with all its dependecies. -
Run
checkoutRelease.shthat will select the current release (3.1) and apply the needed patches. -
Once done, start the build with
build.sh. -
Once the build completes a few hours later, you'll have a
swift-3.1.tgzarchive containing the whole Swift compiler distribution. Once decompressed you'll find the Swift binaries underusr/bin.
I recommend to perform all these operations in a permanent background tmux or screen session (CTRL+B d to detach from the session and tmux a to reattach to it when you ssh again into the RaspberryPi).
Additional steps could be required in some cases (usually on a RaspberryPi 1 or for Raspbian) check the latest posts on my blog for additional info.
