Issue building the exectuables

[decadods]

Environment

macOS 15.0
Xcode 16.0

Description

I cannot build the example on my system. I've tried both building via command line or Xcode but encounter the same issue. What could be missing from my system?

When I try building for release in the terminal:

cyang@Mac-mini live-caller-id-lookup-example-main % swift build -c release

[1588/1590] Linking PIRService

[fboemer]

@decadods , thanks for reporting the issue.
Can you try the latest main (which updates to https://github.com/apple/swift-homomorphic-encryption/releases/tag/1.0.1)?

[decadods]

@fboemer Thanks I tried main which fetched swift-homomorphic-encryption 1.0.1 but it's still failing to link with the same error.

Based on #34 's suggestion the workaround is to place the .swift files in Hummingbird
/Storage under the PIRService folder.

[fboemer]

Thanks @decadods, seems like one more change is needed: #39

[decadods]

@fboemer Thanks this issue was resolved
