aeson+witherable dependency issue building simplex-chat on openbsd 7.7

[machatata]

Describe the bug
building simplex-chat on openbsd 7.7 with ghc 9.8.3 and cabal.

To Reproduce
within simplex-chat git folder, executing:

cabal update

doas cabal install --allow-newer=base,bytestring,template-haskell,text,process simplex-chat:exe:simplex-chat

OR

doas cabal install simplex-chat:exe:simplex-chat

Expected behavior
installation of simplex-chat

System information
OpenBSD 7.7
GHC 9.8.3
cabal-install version 3.14.1.1

Output Error

Warning: The package list for 'hackage.haskell.org' does not exist. Run 'cabal
update' to download it.
Error: [Cabal-7107]
Could not resolve dependencies:
[__0] trying: aeson-2.2.1.0 (user goal)
[__1] unknown package: witherable (dependency of aeson)
[__1] fail (backjumping, conflict set: aeson, witherable)
After searching the rest of the dependency tree exhaustively, these were the goals I've had most trouble fulfilling: aeson, witherable

[geekosaur]

Did you try running cabal update as per the warning?

[machatata]

indeed, ran cabal update,
reran it again just to show this output:
"Configuration is affected by the following files:

• cabal.project
  Downloading the latest package list from hackage.haskell.org
  Package list of hackage.haskell.org is up to date.
  The index-state is set to 2025-05-03T16:54:17Z."

reran the cabal install command and still the same output.

[geekosaur]

Why do you have a cabal.project? Does --ignore-project change anything?

[machatata]

cabal.project was there to begin with in the github repo. there is also a simplex-chat.cabal file in the simplex-chat folder.

interesting, with your suggestion, the output to the following command:

doas cabal install --ignore-project simplex-chat:exe:simplex-chat

is

Warning: The package list for 'hackage.haskell.org' does not exist. Run 'cabal
update' to download it.
Downloading simplex-chat:exe:simplex-chat
Error: cabal: '/usr/local/bin/curl' exited with an error:
curl: (3) URL rejected: Port number was not a decimal number between 0 and
65535

it seems like there is some port issue here.

[geekosaur]

Can you rerun that with -v3 to show the command it's running, please?

[machatata]

i appreciate your patience.
executing:

doas cabal install -v3 --ignore-project simplex-chat:exe:simplex-chat

produces

[geekosaur]

Ugh, that's completely wrong. Sounds like #9817, though.

[machatata]

interesting. thanks for pointing this out. without the --ignore-project addition, i wouldn't have been able to diagnose the issue.

[geekosaur]

In the meantime, you can try using cabal install --ignore-project simplex-chat without naming the executable component. Sadly, if I understand the other ticket correctly, that may not work.

[machatata]

indeed, it does not work with the same port error. i appreciate the help troubleshooting though!

look forward to it perhaps working some time in the future as having a way aside from ssh'ing through VMs on OpenBSD would be convenient.

[ulysses4ever]

There shouldn't be the port error, if, as @geekosaur suggested, you don't specify the component (so, only specify the package name, simplex-chat).

On another note, can you specify what you're trying to achieve:

1. Install an executable from a local checkout of the repository
2. Install an executable from Hackage.

It's either 1 or 2. These are two very different things. If it's 1, then --ignore-peoject is not what you want.

Lastly, please use triple backticks (i.e. ```) on separate lines to delimit your console interactions, not the > sign, which is meant for text quotes.

[ulysses4ever]

Oh, it's not on Hackage, so I guess it's (1).
