Answer 2 · 2019-11-21T16:13:02.000Z

I updated stack and it worked. I guess gitit 0.12.3.2 just cannot be built with ghc 8.0.2?

wiki@mms-wiki:~/devel/gitit$ stack ghc -- --version   
The Glorious Glasgow Haskell Compilation System, version 8.4.3

The haskell motto should perhaps be: Always bring everything with you and ensure you have a few spare hours.

Answer 3 · 2019-11-21T16:52:32.000Z

This due to API change in the filestore package, which should have been marked by a major version bump but wasn't. If you constrain to Diff < 0.4 it should work.

Answer 4 · 2019-11-21T17:26:14.000Z

I'm releasing a filestore update which should help with this.

Answer 5 · 2019-11-21T17:36:52.000Z

Thank you for looking into it.

Answer 6 · 2019-11-21T19:14:59.000Z

The current dev version of gitit should work with both stack and cabal.

Answer 7 · 2020-01-12T23:43:19.000Z

@jgm , when you said this, above:

The current dev version of gitit should work with both stack and cabal.

Did you mean that, if I:

clone the gitit repo (master branch),
move into the resultant gitit directory, and
execute the following commands, in order:
1. cabal configure --ghc
2. cabal build
3. cabal install

that it should work?

I tried the above and got:

cabal: Failed to build gitit-0.12.3.2 (which is required by exe:gitit from
gitit-0.12.3.2).

Answer 8 · 2020-01-13T19:08:25.000Z

looking at our CI, cabal builds seem to be failing now but stack still works.

Answer 9 · 2020-01-13T20:41:31.000Z

The cabal version use hoauth2 >= 1.9.0 and the stack -lts 14.14 used hoauth2 = 1.8.9,
The type of authGetBS (from hoauth2) changes between these two versions.
Having a look at it.

Answer 10 · 2020-01-13T23:31:38.000Z

@capn-freako, I have been able to cabal install gitit by modifying in the file gitit.cabal the lines in the buil-depends section mentioning pandoc, hoauth2 and network:

 pandoc >= 2.8 && < 2.9,
  ...
 hoauth2 >= 1.3.0 && < 1.9,
 ...
 network >= 2.6 && < 2.7,

@jgm , if you think this work on the cabal build is worth a PR, I can submit one.
... There will be more work to upgrade the stack build...

Answer 11 · 2020-01-14T00:52:02.000Z

@freiric , Thank you!

I am confirming that I was able to complete a cabal build/install, using the suggested modifications to gitit.cabal.

Answer 12 · 2020-01-14T01:24:05.000Z

Oh, I spoke too soon.
I'm getting the following run-time error, when I try to launch my newly built gitit executable:

$ /Users/dbanas/.cabal/bin/gitit -f wikidata/my.conf
Could not read mime types file: /etc/mime.types
/etc/mime.types: openFile: does not exist (No such file or directory)
Using defaults instead.

Use -v to see a list of the files searched for.
Could not find module ‘Network.Gitit.Interface’
Use -v to see a list of the files searched for.

The Network.Gitit.Plugin.Ordinal module does appear to be missing from the build/... tree, but the Network.Gitit.Interface module is there.

Answer 13 · 2020-01-14T01:49:25.000Z

@freiric - sure, PR welcome. (Or even better an upgrade to use the latest versions rather than setting an upper bound.) stack build works for me already though.

Answer 14 · 2020-01-14T01:50:04.000Z

Network.Gitit.Plugin.Ordinal is not part of gitit. This must be a 3rd party plugin you're trying to use. Check your conf.

Answer 15 · 2020-01-14T03:04:36.000Z

Apologies; you are correct.
It (cabal-ified) is working fine.
Thanks!

Same (or similar) result from "cabal new-install" and with a current clone of the gitit repo.

Am I using the wrong build incantation? Or maybe too fresh a GHC 8.8.x?

Answer 18 · 2020-03-09T18:42:41.000Z

Looks like it's failing on our GitHub Actions CI as well for GHC 8.8.
This is unexpected, since the PR I merged claimed to be supporting 8.8.
I'll comment over on #646

@conal Does running cabal build in the current clone of the gitit repo (if current, should show as gitit-0.13.0.0) complain about the library MissingH in its error message?

The inability to build MissingH using GHC 8.8.x is an outstanding problem for #646.

Yes it does (with a fresh git pull).

Answer 21 · 2020-03-11T23:23:36.000Z

Has anyone taken any steps to try to get MissingH fixed in Hackage so that it works with GHC 8.8.x? It's not a direct dependency of gitit -- which of our dependencies requires it?

EDIT: haskell-hvr/missingh#52

Answer 22 · 2020-03-11T23:54:53.000Z

There is also haskell-hvr/missingh#51 which has been open with no response from the dev since November, and haskell-infra/hackage-trustees#253.

Gitit depends on it through gitit -> ConfigFile -> MissingH.

Answer 23 · 2020-03-12T00:22:16.000Z

Might be easier to rewrite Network.Gitit.Config to avoid the dependency than to get this fixed. I don't have time for this but maybe someone else would want to.
Looks like https://hackage.haskell.org/package/ini does something similar to ConfigFile with saner dependencies.

Answer 24 · 2020-04-10T17:44:23.000Z

MissingH has updated and released, so rerunning the gitit CI build now should have it succeed on GHC 8.8.

Answer 25 · 2020-04-10T19:10:19.000Z

I'll rerun them.
