Warning: nix (Nix) 2.16.1 is on the PATH (at /nix/var/nix/profiles/default/bin/nix) but Stack's Nix
         integration is disabled. To mute this message in future, set notify-if-nix-on-path: false
         in Stack's configuration.
         

Warning: Stack has not been tested with GHC versions 9.10 and above, and using 9.10.1, this may
         fail.

Error: [S-6362]
       No compiler found, expected minor version match with ghc-9.10.1 (x86_64-tinfo6) (based on
       resolver setting in /home/hecate/.stack/global-project/stack.yaml).
       
       To install the correct version of GHC into the subdirectory for the specified platform in
       Stack's directory for local tools (/home/hecate/.stack/programs/x86_64-linux/), try running
       stack setup or use the --install-ghc flag. To use your system GHC installation, run stack
       config set system-ghc --global true, or use the --system-ghc flag.

In reply to @6d03:matrix.org
is there a way to define cabal dependencies with flags?
