What needs to be done to have ghc-vis running on newest GHC? #29

@def- what work do you think is needed to get this project up and running again?

EncodePanda commented 2 years ago

In other words, how can we help? :)

Since we are working with GHC internals ghc-vis and ghc-heap-view are prone to breaking often. I'll try to upgrade the dependencies in ghc-heap-view and ghc-vis and check where it fails. This should help for ghc-heap-view: https://github.com/nomeata/ghc-heap-view/pull/36

My Haskell foo is a bit rusty, is there an easy way to test cabal install . with the (unreleased) ghc-heap-view 0.6.3?

Anton-Latukha commented 2 years ago

Haskell-foo differs from Cabal-foo.

This should help: https://github.com/haskell-nix/hnix/commit/06b0fca9fd607eb2e995f003424e797a41ffa5b7#diff-b8ed06757045fac949c89f2139a862498ad2b6d1f82c61a31e7c91d6cf0eaa70

There hnix was patched so it would build cryptohash-sha512 dependency from particular git source.

Now that ghc-heap-view is updated, I noticed one further dependency problem: https://github.com/gtk2hs/gtk2hs/issues/309

Haven't gotten that far

I have tried switching to gi-cairo instead of svgcairo. Now I'm running into the next problem:

This seems to be an Arch Linux problem, I'm now trying with cabal build --ghc-options=-dynamic

Edit: Installed extra/gobject-introspection Edit2: gi-cairo doesn't seem to contain everything we require, so this doesn't work.

Edit2: gi-cairo doesn't seem to contain everything we require, so this doesn't work.

What is missing? Does it make sense to create an issue there to accommodate our need?

def- commented 1 year ago

I didn't see anything related to svgcairo
