Module ‘Network.Socket.Internal’ does not export ‘PortNumber’

[demonstrators]

Building a project with LTS-15.0/ghc-8.8.2, I hit the following error:

HaskellNet-SSL                   > [1 of 5] Compiling Network.HaskellNet.SSL
HaskellNet-SSL                   >

HaskellNet-SSL                   >      

Solved by changing import of PortNumber in src/Network/HaskellNet/SSL.hs to:

import Network.Socket (PortNumber)

and by adding network-bsd to cabal file

network-bsd >= 2.8.1,

and by adding following extra-deps in stack.yml

extra-deps:
  - git: git@github.com:jtdaugherty/HaskellNet.git
    commit: 5aa1f3b009253b02c4822005ac59ee208a10a347

and finally, because I didn't want to dig into cabal file versioning, allow-newer in stack.yml

allow-newer: true

All this let's a build against LTS-15.0 complete.

thanks for the great work,
Stephen.

Waiting for an update of the project I had to make a small patch to be able to use this library. Here is the link to an example with haskell.nix : https://github.com/apeyroux/labo-hs-mail

Pointing yourself towards the master of this repo will fix this issue (fixed in ca84ef2). I'm trying to get together a hackage and stackage release before I close this.

Hi Hazelfire, thank you so much for getting this fix in! Any updates on the hackage release (0.3.4.2)?

I just spent 2 hours trying to figure out why my Docker image is not building (and thanks to this thread I was able to fix it!). Would be nice to spare other people this hassle.

Thanks @apeyroux, your fix worked brilliantly!

@Hazelfire Gentle ping for a release ;)

[eyeinsky]

Yet another ping :)

Edit: I think it should be entirely safe to backport the CPP macro to previous versions too?

[Hazelfire]

Finally resolved! Very sorry for the wait. 0.3.4.4 is now on hackage!
