Warning: The install command is a part of the legacy v1 style of cabal usage. Please switch to using either the new project style and the new-install command or the legacy v1-install alias as new-style projects will become the default in the next version of cabal-install. Please file a bug if you cannot replicate a working v1- use case with the new-style commands. For more information, see: https://wiki.haskell.org/Cabal/NewBuild Resolving dependencies...

If the library is already installed but in a non-standard location then you can use the flags --extra-include-dirs= and --extra-lib-dirs= to specify where it is.If the library file does exist, it may contain errors that are caught by the C compiler at the preprocessing stage. In this case you can re-run configure with the verbosity flag -v3 to see the error messages. cabal: Leaving directory '/tmp/cabal-tmp-29335/magic-1.1' Starting microlens-0.4.11.2 Building microlens-0.4.11.2 Completed integer-logarithms-1.0.3 Completed microlens-0.4.11.2 Completed hourglass-0.2.12 Completed basement-0.0.11 cabal: Error: some packages failed to install: git-annex-7.20191009-E23w6nEHhgtH8Tx8586dFh depends on git-annex-7.20191009 which failed to install. magic-1.1-Li4qC2EFmFj3eSH3BrxalF failed during the configure step.
