dyld: Library not loaded: @rpath/lib_InternalSwiftSyntaxParser.dylib after homebrew install

[MattKiazyk]

While related to #60 I'm just simply trying to run generate on the command line after install, so I thought I'd create a new ticket.

Steps:

• Xcode 12.0.1 or 12.0
• Installed beta-5 via homebrew brew install swiftdocorg/formulae/swift-doc
• ran swift doc generate -f html ... via command line

received:

dyld: Library not loaded: @rpath/lib_InternalSwiftSyntaxParser.dylib
  Referenced from: /usr/local/bin/swift-doc
  Reason: image not found

I did not receive this on beta-4 or earlier, granted I had been building it locally when I was making changes, so perhaps that stopped it from happening.

The workaround is to make sure I have my Xcode 12 named Xcode.app. and not Xcode-12.0.1. Once that occurs, and I set my command tools to that - it does not receive that error (albeit getting the #196 issue)

+1 here, also fails for me swift-doc --version

[MaxDesiatov]

My Xcode path is /Applications/Xcode-12.0.0-gm-seed.app.

[MaxDesiatov]

The underlying issue is SR-9038 I guess. Ideally, we want to link all Swift Syntax components statically so that we don't have a dependency on a specific Xcode version.

I was pointed to this guide in README.md of Swift Syntax. We may also need to use install_name_tool to update @rpath.

This should be fixed by SwiftDocOrg/homebrew-formulae@af4cd47.

@MattKiazyk Could you please try reinstalling to verify this?

$ brew uninstall swift-doc
$ brew untap swiftdocorg/formulae # in case you tapped our formula repo
$ brew install swiftdocorg/formulae/swift-doc

[MattKiazyk]

I tried yesterday and it didn't work. Today It did work.

Although got an error when running brew install swiftdocorg/formulae/swift-doc

Error: No available formula or cask with the name "swiftdocorg/formulae/swift-doc".

but running again found it and installed it correctly. Thanks @mattt

@MattKiazyk So glad to hear it! For posterity, here are updated commands to run for anyone else who may be getting that error message:

$ brew uninstall swift-doc
$ brew untap swiftdocorg/formulae # in case you tapped our formula repo
$ brew tap swiftdocorg/formulae
$ brew install swift-doc

You may have also noticed that installation is now much faster thanks to the formula now having a bottle (e.g. pre-built binary).

Again, apologies for any inconvenience I may have caused by botching the distribution of this release. I've learned a lot more about Homebrew, and have taken this as an opportunity to improve the process going forward. Hoping to write up what I've learned in a blog post soon.
