Compile error on Linux

[thbonk]

Hello,

I'm using HAP in a project which depends on NetService. When I compile my project on Linux,
I'm getting errors like:

/home/travis/build/MiCasa-HomeKit/MiCasaPlugin/.build/checkouts/NetService/Sources/NetService/NetServiceBrowser.swift:181:66: error: cannot find 'kCFSocketReadCallBack' in scope
372        socket = CFSocketCreateWithNative(nil, fd, CFOptionFlags(kCFSocketReadCallBack), _processResult, &context)

These errors occur in several files. You can find the full log at:
https://travis-ci.org/github/MiCasa-HomeKit/MiCasaPlugin/jobs/740481068

This is my .travis.yml file:
https://github.com/MiCasa-HomeKit/MiCasaPlugin/blob/feat-%231-setup-ci-cd-pipeline/.travis.yml

Best regards
Thomas

I don't fully understand why this started happening. There has been no change on my side, and master used to run fine on Linux on Swift 5.1 and 5.2. However it is now failing indeed. The apt packages installed in both tests are the same versions:

Unpacking libdaemon0:amd64 (0.14-6) ...
Unpacking libavahi-core7:amd64 (0.7-3.1ubuntu1.2) ...
Unpacking avahi-daemon (0.7-3.1ubuntu1.2) ...
Unpacking libavahi-common-dev:amd64 (0.7-3.1ubuntu1.2) ...
Unpacking libdbus-1-dev:amd64 (1.12.2-1ubuntu1.2) ...
Unpacking libavahi-client-dev:amd64 (0.7-3.1ubuntu1.2) ...
Unpacking libavahi-compat-libdnssd1:amd64 (0.7-3.1ubuntu1.2) ...
Unpacking libavahi-compat-libdnssd-dev:amd64 (0.7-3.1ubuntu1.2) ...
Unpacking libnss-mdns:amd64 (0.10-8ubuntu1) ...

See failing test and succeeding test.

I've fixed this in #38. I still don't know why the variable was no longer set on Linux.
