Hi @PiJoKra,

So you are trying to boostrap cabal using only GHC? I'm afraid that's not trivial. Please look at the last line of https://github.com/haskell/cabal/blob/master/README.md and let us know if that works for you.

[LiraOnGithub]

Hello @Mikolaj
Thank you for pointing me there!
I only see json's for ghcversions going up to 8.10.7, can I use cabal for ghcversion 9.2.1?

The reason for trying to bootstrap is me not getting cabal via the package-manager to work for ghc 9.2.1
After sudo apt install cabal-install, running cabal configure --with-compiler=/usr/local/bin/ghc yields:

Warning: Unknown/unsupported 'ghc' version detected (Cabal 2.4.0.1 supports
'ghc' version < 8.7): /usr/local/bin/ghc is version 9.2.1

And running `cabal install cabal-install yields:

cabal v2-install cabal-install
Warning: Unknown/unsupported 'ghc' version detected (Cabal 2.4.0.1 supports
'ghc' version < 8.7): /usr/local/bin/ghc is version 9.2.1

OOI, did you try the newest one and it didn't work?

I wouldn't worry about the warning. Which point of https://github.com/haskell/cabal/blob/master/README.md are you following now? If the "Installing cabal-install (preferred, with cabal-install)" one, did you do cabal update?

It did not work. This is was the result:

I also find it strange there are packages in both /usr/local/lib/ghc-9.2.1 and in ~/.cabal/packages/hackage.haskell.org, but not sure if it has anything to do with it.

[Mikolaj]

Thank you for the details about bootstrapping. Good to know.

Two locations for packages is fine --- one comes with the GHC, another stores user-downloaded packages.

Reading your log, it seems cabal 3.6.2 indeed rules out newer GHCs. Even GHC 9.0.2 is off-limits. The version in the repo probably accepts 9.0.2, but not 9.2.*.

I'm afraid, the only remaining options are downloading the binary, either via ghcup or as told in the README. Cabal doesn't mind being compiled with one GHC and used with different ones.

[Mikolaj]

I guess we should amend the README to say "but not with bleeding edge GHC" or something to that effect, so that others don't need to repeat our investigation. What text would help you, initially?

[Mikolaj]

Especially that the way that doesn't work two last versions of GHC is marked as "preferred".

[LiraOnGithub]

I think the "but not with bleeding edge GHC" would be good enough, or maybe state that the json-files with the ghcversion-naming dictate the last version you can use or something like that.

[Mikolaj]

Good idea, thank you.

[Mikolaj]

@fendor also suggests to add to the .cabal file (I'd say, the minimum would be cabal-install.cabal) the "tested-with section to indicate with which GHC version you are supposed to be able to build". That'd require some maintenance though, from both ends; in particular removing GHCs we no longer support.

[LiraOnGithub]

Seems like a good idea! Should I rename this issue to something to reflect cabal not working with recent GHC-versions?

I decided to try my luck with ghcup and now have cabal-install version 3.6.2.0, but now I always get the following when using cabal install PACKAGENAME:

Resolving dependencies...
cabal: Cannot build the executables in the package PACKAGENAME because it
does not contain any executables. Check the .cabal file for the package and
make sure that it properly declares the components that you expect.

I tried multiple packages. Is this related to the previous problem, or is this something I should create a new issue for?

[Mikolaj]

That would make sense.

I tried multiple packages. Is this related to the previous problem, or is this something I should create a new issue for?

I think this works as expected. You normally don't install packages by hand, unless they have an exe you need. Cabal installs everything it needs automatically when you cabal build a package you are working with. Unless you have some special needs that require installing packages manually, in which case, please describe them.

[Mikolaj]

Again, if dev version of cabal docs is misleading in this respect, let's fix them: https://cabal.readthedocs.io/en/latest/

[LiraOnGithub]

Oh, I had a .cabal with the package in it, but removed and started over. Now the package was no longer in the .cabal and cabal complained it could not load a module. I got a bit confused :')
It works now, thank you!

I'm afraid, the only remaining options are downloading the binary, either via ghcup or as told in the README. Cabal doesn't mind being compiled with one GHC and used with different ones.

Yes. ghcup.

Nix is also always an option.

After the Nix installation & restarting the terminal - run the nix-env -iA nixpkgs.cabal-install. To be honest - if that does not work - it is easier to direct towards learning Nix than explaining/debugging.

Overall the good rule of thumb - is not to use package managers to install other package managers. Most often, having each package manager/management installed in the official package management way, or at least as a separate custom deployment / structural dependency tree with independent root (package manager) - the more comfortable & stable usage is.

[LiraOnGithub]

I have another bug and want to check if it has to do with this one. If not I can make a new issue.
When I try to run the project it cannot determine the version of /usr/local/bin/hsc2hs-ghc-9.2.1.

And is there /usr/local/bin/hsc2hs-ghc-9.2.1?

Is that installed with ghcup? If so, is 9.2.1 the only version installed with ghcup or is it made the default version by command "set"?

Mmm, that is strange... It expects the version number in the name...

Seems to not be an issue with cabal though... Thanks anyway ^^'

[Mikolaj]

Looks like scripts left over from previous installation?

[LiraOnGithub]

Could be the reason. Renaming /usr/local/bin/hsc2hs-ghc-9.2.1 to /usr/local/bin/__hsc2hs-ghc-9.2.1 fixed it. Now everything seems to work as expected. Thanks :)

FWIW, while looking to upgrade Void to GHC 9.0.2 (not 9.2.2) I did manage to create a linux-9.0.2.json for Cabal-3.6.3.0 by following this, which then bootstrapped cabal correctly for 9.0.2. All I had to do was relax the bounds in cabal-bootstrap-gen.cabal a little and apply

(I know that this post was originally about 9.2.1., but the title says "recent versions of GHC" so perhaps this will still help someone)

@Mikolaj From what I have seen, the cabal-install releases 3.2.0.0, 3.4.0.0, 3.4.1.0 and 3.6.2.0 have source downloads that are unable to bootstrap. The 3.6.2.0 also does not have a valid checksum in https://downloads.haskell.org/~cabal/cabal-install-3.6.2.0/SHA256SUMS . Will the cabal-install source code release be able to be built in isolation in the future?

[Mikolaj]

@okeuday, thank you for your comments.

From what I have seen, the cabal-install releases 3.2.0.0, 3.4.0.0, 3.4.1.0 and 3.6.2.0 have source downloads that are unable to bootstrap.

I think the instruction for bootstrapping

https://github.com/haskell/cabal/tree/master/bootstrap

involve manually copying boostrap files from the repo. There is #7289 about including the files somewhere, but is downloading them really such a burden? It's not supposed to be a streamlined process, anyway --- for comfort you use cabal. Nor is it supposed to be exhaustive, since the person porting cabal may have yet another version of GHC or other special circumstances that we can't predict in advance.

The 3.6.2.0 also does not have a valid checksum in https://downloads.haskell.org/~cabal/cabal-install-3.6.2.0/SHA256SUMS.

Well spotted. If you that's crucial for you, please open a ticket. Is https://downloads.haskell.org/~cabal/cabal-install-3.8.1.0-rc1 OK in this respect? This should be the same in 3.8.1.0, to be released RSN.

Will the cabal-install source code release be able to be built in isolation in the future?

We don't have such plans, but we welcome discussion and contributions.

[ulysses4ever]

Should this be closed due to inactivity and no clear goal?

[andreabedini]

👍 I am keen to make sure everything mentioned in this thread works but I am not sure what does not (or did not).

[okeuday]

The clear goal was to have cabal-install compile from source. What is unclear is why cabal-install is unable to have a source code release that always compiles correctly from source (i.e., bootstrapping). Releasing opaque binaries isn't a valid solution.

[gbaz]

cabal-install can compile from source and bootstrap. It just requires that it be compiled with the versions of ghc it is targeted for, and not other versions. I don't think there is an actionable issue here.

[okeuday]

@gbaz Other compilation would make the version dependency explicit in the build process, so it is clear. I see no reason why cabal-install is unable to do that for its dependency on ghc. Adding the explicit version dependency would be an actionable change that is possible.

[ulysses4ever]

All right, let's inspect more. @okeuday could you, please, update the issue description (the top post) with your current problem? We need a precise description of your environment, i.e. versions of tools you're using, and what you're trying to achieve, i.e. whethere you're bootstrapping or trying to cabal install cabal-install. If you're bootstrapping, don't hesitate to first consult with https://github.com/haskell/cabal/blob/master/bootstrap/README.md first.

[okeuday]

@ulysses4ever It has been more than 1 year since I checked cabal-install compilation of various versions, so I don't remember all the details. It looks like I was using GHC 9.2.4 for cabal-install 3.6.2.0, GHC 9.0.2 for cabal-install 3.4.0.0, GHC 8.10.7 for cabal-install 3.2.0.0, at that time (each of those cabal-install source code compilations failed). I don't have more time to spend on cabal-install at this point in time. The removal of sandboxes helped me to avoid it as a dependency, so I don't use cabal-install as much now.

[ulysses4ever]

Thank you for explaining your case. I'm afraid we can't move forward with this issue without a clear explanation what the goal was and where it failed.

If the issue raises again, please feel free to open a new ticket with a clear reproducer.
