Re: [Haskell-beginners] Installing HDBC

BTW, I'm doing this on a Windows Vista PC... ----- Original Message ----- From: "Kathleen Lynch" To: "Daniel Fischer" Cc: Sent: Tuesday, February 01, 2011 2:20 PM Subject: Re: [Haskell-beginners] Installing HDBC

I entered the command you gave me: cabal install HDBC-sqlite3 It returned the following error: Resolving dependencies... Configuring HDBC-sqlite3-2.3.1.0... cabal: Missing dependency on a foreign library: * Missing C library: sqlite3

I then went to the link you provided: http://hackage.haskell.org/package/HDBC-sqlite3 I extracted the tar file, HDBC-sqlite3-2.3.1.0.tar, and tried to un-tar it but get the following message: "Error reading header after processing 0 entries"

I'd appreciate any help...

It's in http://hackage.haskell.org/package/HDBC-sqlite3

$ cabal install HDBC-sqlite3

(similarly for mysql, postgresql, odbc). I suppose those packages depend on having the foreign library installed, so they come alone. It's a bit annoying (especially if one is not told which packages one needs), but having to install multiple databases when one wants to use only one would be at least as bad.
