Segmentation Fault

[esttorhe]

Version swiftgen 0.5.0_1 installed with via brew doesn't work and throws the following error no matter what command I try :(

Tried with Xcode 7 and Xcode 7.1

swiftgen
[1]    72547 segmentation fault  swiftgen

That's probably because it has detected your Twitter name and want to troll you 😉

But seriously, when installed via brew and especially if Homebrew did pour the "bottle" (= the precompiled version of swiftgen directly downloaded via a .tar.gz) instead of compiling it on your machine locally during installation, then swiftgen will have a @rpath set to some path inside /Applications/Xcode.app/… so that's where it's gonna look for the Swift dylibs to load. Even if that version installed at that path is in fact Xcode 6.

I added a protection in SwiftGen's formula to only use the bottle if the path /Applications/Xcode.app exist on your machine but didn't check that the version at that path was Xcode 7.0.1. I'll bet that's not the case for you and that's the cause of the SegFault because SwiftGen will then load Xcode 6's Swift libs instead of Xcode 7's ones, no matter what xcode-select -p you have.

Could you rename your Xcode 7.0.1 to /Applications/Xcode.app and try again?

[esttorhe]

Oh! The twitter handle irony 😂

I do have a symlink pointing to 7.1; don't know if that's the issue or if it should be pointing to 7.0.1 instead.

I'll try changing it anyways.

Xcode.app -> /Applications/Xcode-7.1.app

Changing the symlink to 7.0.1 and «re-pouring» the bottle fixed it 🍻

Don't know if 7.1 doesn't work for this or what ¯_(ツ)_/¯

I'm closing it. Thanks 🙇

[AliSoftware]

I don't like it. One more restriction when installing via homebrew.

I'll make a 0.5.1 that copies Swift libs over so it's independent of your Xcode install path and will hopefully solve this once and for all.

@esttorhe SwiftGen 0.5.1 just got merged into Homebrew; could you test it (with your symlink reset to 7.1 like when you had the issue) and tell if it fixed it?

Thx!

[esttorhe]

@AliSoftware just tested with the symlink back at 7.1.

Uninstalled swiftgen and reinstalled via homebrew and is working now 👌
