Installed hBDD-0.0.2 Configuring hBDD-CUDD-0.0.2... cabal: Missing dependencies on foreign libraries: * Missing (or bad) header file: cudd.h * Missing C libraries: cudd, mtr, st, epd 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. 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. Failed to install hBDD-CUDD-0.0.2 cabal: Error: some packages failed to install: hBDD-CUDD-0.0.2 failed during the configure step. The exception was: ExitFailure 1
