cabal: Error: some packages failed to install:
HDBC-odbc-2.2.3.2 failed during the building phase. The exception was:
ExitFailure 1

What can I do for this?

Answer 1

You need to install the unixodbc c-library which the HDBC-odbc Haskell wrapper wants to link against, for Ubuntu/Debian this is accomplished by

sudo apt-get install unixodbc-dev

For YUM/RPM based Linux distribution this should be something along

sudo yum install unixODBC-devel
