Hey Chris, I've been fiddling around with the database stuff myself and I had the same problems (on Linux). I eventually got both HaskellDB and HSQL to work, and am now using HSQL because HaskellDB had very poor documentation. I don't exactly know how I eventually got HSQL-MySQL to work, but I think it might be the case that you need to install a MySQL dev package first, as the haskell package only contains bindings to it. Good Luck, Paul P.S. It's nice to see I'm not the only one going into a Haskell frenzy after the exams. Chris Eidhof wrote:
Hey everyone,
I'm figuring out how to do databases in Haskell (on OS X). So far, I've tried the following approaches:
1. hdbc. I'd like to connect to MySQL, so I need the ODBC backend. I couldn't get this to work under OS X, while I installed myodbc, which seems to be broken.
2. hsql. The packages on hackage don't compile, so I grabbed the darcs version. hqsl itself installed perfectly, but when I try to compile hsql-mysql, it does not recognize that hsql is already installed and tries to recompile. Compiling fails, so I generated a .tar.gz of hsql using cabal sdist, put it in the .cabal/packages directory in the right place, and finally, it does compile. Now hsql-mysql starts compiling, but it finally fails with:
MySQL.hsc:270:0: error: ‘MYSQL_NO_DATA’ undeclared (first use in this function)
MySQL.hsc:270:0: error: (Each undeclared identifier is reported only once
MySQL.hsc:270:0: error: for each function it appears in.)
So what is the state of hsql? And haskelldb? Are they actively maintained?
