Sorry to complain, but you also forgot to update the .SRCINFO ;)

@wezm Sorry, that should be fixed now. I somehow managed to miss committing a small but necessary change that therefore broke swiftc.

FYI I installed this and tried to build some projects that use swift package manager and they all failed with an error like, "The manifest file at /path/to/a/file is empty". I then built swift form source using the swift AUR package, which also has the 4.0.3 version and it appears to work.

Orphaning it. Refi.64, here you go. Good luck :)

@FredBezies Ok, that would be great!

@refi.64 : if you want it, I can orphan it in order to give it to you. Just ask.

@FredBezies: I guess so? I mean, I'm working on some Swift projects (I used Ubuntu before, and haven't been able to work on them since switching to Arch, because of obvious reasons), so I guess I have some incentive. ;)

@refi.64: if you want to adopt swift-bin package, I'll give it to you. I'm not using anymore this package. So...

After a long time of experimenting with various things, I FINALLY have a fully, 100% working version of the Swift binaries. No more libcurl errors, no more version warnings, no more include header issues.

Of course, the con is that this is a hot mess. It creates a custom ld.so without version warnings (to ensure that building works), patches the proper libcurl.so (same thing), and - worst of all - uses bubblewrap to add a custom clang++ that patches ld.so on all built files. It's a hot mess, but it works perfectly. I've successfully built several sample applications with it.

Here's the patch:
