Doesn't compile with the Linux Static SDK (aka musl) #330

Closed sebsto closed 1 week ago

sebsto commented 2 weeks ago

Expected behavior

Now that the Static Linux SDK has been released, it open the doors to cross-paltform compilation from Mac that doesn't require Docker or depend on Amazon Linux.
In theory the binary created with the Static Linux SDK should work "as is" on AWS Lambda.

To make this happen, the AWS Lambda Runtime must slightly adjust the way it detects Linux and import Glibc.

I'll send a PR to fix this in a moment.

Actual behavior

Compilation errors such as 

swift-aws-lambda-runtime/Sources/AWSLambdaRuntimeCore/Lambda.swift:16:8: error: no such module 'Glibc'
 14 | 
 15 | #if os(Linux)
 16 | import Glibc
    |        `- error: no such module 'Glibc'
 17 | #else
 18 | import Darwin.C

Steps to reproduce

  1. Install the Linux Static SDK (doc)
  2. Apply the patch as described in this message
  3. Compile with swift build --swift-sdk aarch64-swift-linux-musl

If possible, minimal yet complete reproducer code (or URL to code)
