Swift on FreeBSD

MajorTom · 2020-02-23T08:07:01.435Z

I agree that having FreeBSD support would be great. For Swift to make a serious dent, it needs to to support Windows and FreeBSD.

jims · 2020-02-26T23:04:43.120Z

Regarding __stdlib_remainder() and __stdlib_squareRootl() not being found, I believe this stems from not having a typealias for CLongDouble.

It certainly seems counterintuitive, but if you look in stdlib/public/core/CTypes.swift you will find code where OS and architecture are considered and a CLongDouble possibly defined. Adding an #elseif case for my OS and including…

public typealias CLongDouble = Float80

… cleared up the problem for me.

Depending on your architecture, you may also have to adjust the guards in stdlib/public/SwiftShims/LibcShims.h.

Any Christmas gifts for BSD lovers?

mko_io · 2020-12-13T14:52:35.078Z

OpenBSD is the lucky one, someone has ported swift to Openbsd.

I hope FreeBSD can also get some love from Swift Community

GrandFelix · 2020-12-13T15:03:26.658Z

Great to read that! I also hope for FreeBSD to be on the list if supported OS.

The OpenBSD port has been done!

OpenBSD port status and tracking Related Projects

This post is intended to be some supplemental documentation for getting Swift and its components running on OpenBSD and describe context on the state of the port. This is done here on the forums in order to more dynamically and rapidly augment "more official" in-tree documentation, which requires pull requests and reviews to update. Getting the compiler and stdlib built Follow the in-tree documentation (docs/OpenBSD.md). Take special care to the symlinks section -- don't just blindly copy an…

What’s the best things to do to port Swift to FreeBSD 13.1 ? And how much!?

Finagolfin · 2022-05-27T14:20:17.662Z

What’s the best things to do to port Swift to FreeBSD 13.1 ? And how much!?

I would encourage you or anyone else interested to look at the pulls making up @3405691582's OpenBSD port over the last couple years, which give you an idea of the work involved, as I noted on another FreeBSD thread late last year. FreeBSD may be less work, as I already see some support merged.

GrandFelix · 2022-09-13T17:27:28.510Z

Anything new here?

kebo · 2022-09-20T00:02:26.317Z

This is a good sign.

Initiative: Swift Platform Work Group Pitches

Swift Platform Work Group (tentatively named) is a new Swift community workgroup, working together to improve platform usability of Swift. This includes: Expanding available target platforms for Swift. SPWG should embrace community works in cross compilation area, and, help the community to contribute related changes to upstream. So far, the most heated areas are Android (separatedly maintained by @Finagolfin and the Readdle team) and WebAssembly (by @Max_Desiatov and others in SwiftWasm comm…

MajorTom · 2022-10-23T15:01:04.455Z

Maybe not. They list lots of other platforms, but not FreeBSD.

jollyjinx · 2023-05-06T05:55:50.209Z

Has anybody gotten swift on FreeBSD to work ? I've tried the excellent instructions on swift/FreeBSD.md at freebsd-docs · mhjacobson/swift · GitHub inside a FreeBSD 13.2 jail (applying the module patch on the basejail) and gotten to the point during the build where ninja starts to compile swift code.
Now I get a segmentation fault in

4.      While evaluating request ASTLoweringRequest(Lowering AST to SIL for module Swift)
5.      While silgen emitFunction SIL function "@$ss3minyxx_xxxdtSLRzlF".
 for 'min(_:_:_:_:)' (at /root/swift/swift/stdlib/public/core/Algorithm.swift:38:8)

But I have no idea how to debug ninja. I've loaded the core in lldb but there is not really anything there

[root@swift ~/swift/build]# lldb -c ./tools/swift/stdlib/public/core/swift-frontend.core 
(lldb) target create --core "./tools/swift/stdlib/public/core/swift-frontend.core"
Core file '/root/swift/build/tools/swift/stdlib/public/core/swift-frontend.core' (x86_64) was loaded.
(lldb) bt all

  * frame #0: 0x0000000001a64933
    frame #1: 0x000000087cc8e300
(lldb)

Any idea how to get it running ? I've tried contacting the author of the FreeBSD build instructions, but got no answer. That's why I'm shouting out here for help.

mko_io · 2023-05-06T05:59:31.971Z

jollyjinx:

swift/FreeBSD.md at freebsd-docs · mhjacobson/swift · GitHub

I think once the Swift 5.9 and new swift based Foundation library become stable, we can re investigate this problem.

Finagolfin · 2023-05-06T11:42:10.130Z

What version of Swift are you building? What is the failing command? I assume this is FreeBSD amd64.

I've seen a similar error when bootstrapping on linux x86_64: try turning the bootstrap off, -DBOOTSTRAPPING_MODE:STRING=OFF.

jollyjinx · 2023-05-06T12:00:29.181Z

Thanx for the hint - as said I'm using the configure script from mhjacobson/swift , which has
-DBOOTSTRAPPING_MODE=BOOTSTRAPPING
enabled.

I did disable it and ..... it compiled fine!!!

I just ran my first 'hello world' on freebsd:

[root@swift ~/swift/build/bin]# ./swift helloworld.swift 
hello world
[root@swift ~/swift/build/bin]#

swiftc to compile it also worked and I only had to set the correct library path to get it working!

So in essence:

To get swift compile on FreeBSD follow the instructions on:

github.com

mhjacobson/swift/blob/freebsd-docs/docs/FreeBSD.md

# Swift on FreeBSD

This document outlines the steps involved in building and using Swift on the
[FreeBSD operating system](https://www.freebsd.org).

## Prerequisites

Swift requires a base system of FreeBSD
[13.1-RELEASE](https://www.freebsd.org/releases/13.1R/)
or newer.[^why-13.1]

[^why-13.1]: FreeBSD 13.1-RELEASE contains two fixes required to build Swift.
First, it
[comes with](https://github.com/freebsd/freebsd-src/commit/349cc55c9796c4596a5b9904cd3281af295f878f)
a toolchain based on LLVM 15, which means that its `lld` supports
`-start-stop-gc`.  Second, it
[uses](https://github.com/freebsd/freebsd-src/commit/c00d345665366a89aaba7244d6f078dc756f4c53)
the `unwind.h` from LLVM's
libunwind, not the one from `libcxxrt`, which requires `_GNU_SOURCE` to be
defined in order to call `_Unwind_Backtrace`.  See

This file has been truncated. show original

change bootstrapping mode in configure.sh to off:
-DBOOTSTRAPPING_MODE=OFF \

and everything compiles

kebo · 2023-05-06T18:42:34.049Z

What version of Swift did you build?

I tried to build with release/5.8 branches following the instructions, but I got the following errors:

mkdir build
cd build

../../configure.sh

with the configure.sh script containing:

I got swift to build.

For build-script options and arguments that you find work successfully, would you mind submitting a PR to build-presets.ini with a FreeBSD-specific preset so that it's easily reproducible?
