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-31977/pulse-simple-0.1.14' Starting syb-0.7.1 Building semigroups-0.19 Building syb-0.7.1 Completed semigroups-0.19 Completed hashable-1.2.7.0 Completed syb-0.7.1 Completed primitive-0.7.0.0 cabal: Error: some packages failed to install: essence-of-live-coding-pulse-0.1.0.1-8oqMymsSUAI6Rb9CWaju0F depends on essence-of-live-coding-pulse-0.1.0.1 which failed to install. pulse-simple-0.1.14-73roEnm0FT8BKKaG1fpqhL failed during the configure step.
