If you do not need a custom Setup.hs or ./configure script then use 'build-type: Simple'. setup: Missing dependencies on foreign libraries: * Missing C libraries: ssl, ssl, sqlite3 This problem can usually be solved by installing the system packages that provide these libraries (you may need the "-dev" versions). If the libraries are already installed but in a non-standard location then you can use the flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are. cabal: Leaving directory '/tmp/cabal-tmp-918/harchive-0.1' cabal: Error: some packages failed to install: harchive-0.1 failed during the configure step.
