The problem is that hsc2hs doesn't recognize all flags from
'mysql_config --cflags'. The hsc2hs tool have to receive only -I and
-D options from cc-options field in the .cabal file. This is fixed in
the recent (CVS) Cabal version but it isn't available in the current
release. I discovered the trouble shortly after the last HSQL release.
You can change the package description manually to workarround the
trouble.

I've just downloaded and tried to build HSQL for MySQL but I'm getting the errors below. mysql.h does exist. Any help would be appreciated.
Thanks, Dominic.

Upgrading to MySQL 4.1 fixed this problem for me, but introduced another one:

The problem is that GHC doesn't support all the flags output by mysql_config:
[bjorn@burns MySQL]$ mysql_config --cflags -I/usr/include/mysql -mcpu=i486 -fno-strength-reduce
I have fixed the CVS version of HSQL to use "mysql_config --include" instead. So the solution for you is to upgrade MySQL, and either change "--cflags" on line 76 in HSQL/MySQL/Setup.lhs to "--include" or get HSQL from CVS.
