Failed to install hBDD-CUDD-0.0.3 Build log ( /home/builder/.cabal/logs/hBDD-CUDD-0.0.3.log ): cabal: Entering directory '/tmp/cabal-tmp-1889/hBDD-CUDD-0.0.3' Configuring hBDD-CUDD-0.0.3... cabal: Missing dependencies on foreign libraries: * Missing (or bad) header file: cudd.h * Missing C libraries: cudd, mtr, 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. cabal: Leaving directory '/tmp/cabal-tmp-1889/hBDD-CUDD-0.0.3' cabal: Error: some packages failed to install: hBDD-CUDD-0.0.3 failed during the configure step. The exception was: ExitFailure 1
