Arch Linux User Repository

While I was able to build this in a clean chroot, consider this package to be a wip.

• According to this comment, swift does need swift to build. So if you haven't previously built this package, you'll need aur/swift-bin.

• This package attempts to install only swift to /usr/lib/swift.

  • Building (5.9.2) takes about 15GB. Package is 650MB. Installed size is 2GB.
  • cmark and llvm are built, but not installed. If they are installed, space requirement increases to 20GB, package is 2GB, and installed size 7GB.
  • Above space requirements count only the build tree. Does not include space needed to download and install depends. Does not include temporary files that may have been created and deleted by the build system.
  • I don't know if everything actually works correctly. Someone who knows better would have to check. (I would use swift-bin, especially since it's already needed to build this.)

• This package does not make debug symbols. With debugging enabled, over 70GB would be required to build. I don't know package or install size because I hadn't figured out how to install at that time.

to speed up check out of the repositories, use shallow or sparse clone, e.g.:

  GITFLAGS="--depth=1" paru -S swift-language

other options to install swift are currently:

• swift-bin, which repackages tachoknights official released centos8 build: https://aur.archlinux.org/packages/swift-bin/. the install is quick, no hours of waiting until everything is compiled.

• latest from git, in swift-language-git. there is a binary built with github actions, but this build is not particularly stable, sometimes it uses more resources than github allows, sometimes it fails for a change upstream. the version number is taken out of the official tag on apple/swift main branch: e.g. swift-language-git-swift.DEVELOPMENT.SNAPSHOT.2020.09.28.a.r208.g6651f6e55d4-1-x86_64.pkg.tar.zst. so this one is the development tag from sep 28 + 208 commits, the commit hash is g6651f: aur - https://aur.archlinux.org/packages/swift-language-git. gh-actions: https://github.com/soloturn/swift-aur/releases/tag/latest

there was an 5.4.1 binary build, native arch, by fanjiang, built on GCE: https://github.com/ProfFan/swift-aur/releases

I'm no expert, but it seems that the downstream fedora package has been updated to v 5.1.5, so the PKGBUILD is not working. Can you update the PKGBUILD file when you have a few mins please?

@Zrax Thanks for the patch. I have finally been able to install it

Thanks, I've added the Python 3.8 fix

The problem is that the normalize test doesn't support python3.8.

See https://github.com/commonmark/cmark/commit/68c3a91166347a32a57fb81223750a63cfd92105

Any suggestions?

@eagleflo Not sure what happened, but a fresh build confirms your checksum, so I've updated it to match... Thanks

The SHA sum for swift-5.1.2-RELEASE.tar.gz was off for me.

Just tried to build swift 5.1-1, and I ran into a different error:

Any ideas?

EDIT: I seem to have fixed the compile error by modifying src/swiftpm/Sources/Basic/Process.swift:

Not sure if this is the correct/preferred solution, but it worked for me.
