Sqlite.swift: Installing via Swift Package Manager - build errors

[kartikthapar]

TL;DR: Is this supposed to work on the mac?

---

Installed via the swift package manager using:

.package(url: "https://github.com/stephencelis/SQLite.swift.git", from: "0.11.5")

for a Vapor 3 project. A bunch of issues due to the bridging header. I wonder if its how Vapor generates the project or if these headers are just incompatible.

I have the same issue from a swiftpm project, but they only occur in the generated Xcode project, not when building/running from the commandline.

@kiliankoe Same as you. I was wondering why SQLiteObjc is necessary so I removed it and the errors are gone but a new one appear:

UPDATE:

That happens because SQLiteRegisterTokenizer is defined in the SQLiteObjc 😅🤦‍♂️

[ricardopereira]

Ok, I think it's an SPM issue (more precisely, the swift package generate-xcodeproj command). The SQLiteObjc target is using the default compiler (in my case, Swift compiler). So, you need to change the Clang Build Settings for that target to use C:

And it compiles successfully 🙌
