Why does it reject the base library? The versions conflict, but why does it think the version should be base-4.18.1.0? The library compiles okay on my machine (using "cabal build"). I have this in the hsshellscript.cabal file, under "build-depends:": base >= 4.13.0 && < 4.14
I've got this version information from calling "cabal gen-bounds". 4.13 was shipped with GHC 8.8 and 4.18 was shipped with 9.6. See https://wiki.haskell.org/Base_package
I guess you called "cabal gen-bounds" with ghc version 8.8 in your PATH
That's correct.
but you're now trying to install the library with ghc 9.6 in your PATH.
No, I'm just trying to upload it to Hackage properly. That's where I got that error.
The solution is most likely to change the base bound to < 4.20 (so it works with every version of base released so far).
Why aren't all the base package versions available? I thought this was one of the purposes of the Cabal system... And wouldn't it be better to remove the upper bound entirely?
You can avoid uploading a new version of your package by making a package revision to do this, accessed via the link "edit package information" under your package's Hackage page.
Thanks!! I'm editing the package information next. Cheers, Volker
