Please try the latest GzipSwift 4.0. ref. #14

I'm having this issue as well, even with GzipSwift 4.0. I'm on Xcode 9 with Swift 4. I can reproduce this issue within xcode or compiling on command line with this swift package:

https://github.com/krze/GzipIssue

  1. Check out this repo
  2. Run swift build -c release
  3. Note the errors for the redeclaration of zlib

The issue is fixed if you remove zlib from Gzip's depdendencies (fork here: https://github.com/krze/GzipSwift)

Aha, sorry, I forgot about SPM + Apple devices. I have to update Package.swift somehow...

@krze @1024jp checkout my fork here https://github.com/danramteke/GzipSwift which fixes this problem using Swift Package Manager on Mac and Linux.

I suppose this issue was fixed on GzipSwift 4.0.3, which I've just released, thanks to #23. Please tell me if the matter still exists.
