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