Failed to install cedict-0.2.2 Build log ( /home/builder/.cabal/logs/cedict-0.2.2.log ): cabal: Entering directory '/tmp/cabal-tmp-28234/cedict-0.2.2' Configuring cedict-0.2.2... cabal: Missing dependency on a foreign library: * Missing (or bad) header file: c/data.h This problem can usually be solved by installing the system package that provides this library (you may need the "-dev" version). 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 header 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-28234/cedict-0.2.2' cabal: Error: some packages failed to install: cedict-0.2.2 failed during the configure step. The exception was: ExitFailure 1
