i'm new to haskell and i'm assume you're trying to compile all the stuff "by hand", instead why don't you install cabal and install them using cabal? i'm trying also to use database with haskell,i use cabal to install HDBC this way:(from my comments in code) -- install those modules with cabal: /usr/local/bin/cabal update (if needed) /usr/local/bin/cabal install HDBC Damien Le 05/12/2018 12:15, Eyüp Kaan AKAY a écrit :

Hi. I want to use sqlite3. When I work to install it, I got this error: *hdbc-sqlite3-master$* ghc --make -o setup Setup.lhs *hdbc-sqlite3-master$* ghc --make -o setup Setup.hs [1 of 1] Compiling Main ( Setup.hs, Setup.o ) Linking setup ... *hdbc-sqlite3-master$* ./setup configure Configuring HDBC-sqlite3-2.3.3.1... setup: At least the following dependencies are missing: HDBC >=2.3.0.0, utf8-string -any

When I want to install HDBC, I got this error:

*HDBC-2.4.0.2$* ghc --make -o setup Setup.lhs *HDBC-2.4.0.2$ *./setup configure Configuring HDBC-2.4.0.2... setup: At least the following dependencies are missing: convertible >=1.1.0.0, utf8-string -any

Then I install convertib le and I got any errors then first I work to install HDBC but I got the same error. So what can I do else?
