[Haskelldb-users] DBDirect ELF incompatibility (zlib) when using mysql driver

[Marc W. <mar...@gm...>]

I get this error after having compiled DB Direct with.
Glasgow Haskell Compiler, Version 6.5.20060117, for Haskell 98, compiled
  by GHC version 6.5.20060117
with latest hs-plugins (from darcs)
with cmdline : ghc -lz -fallow-undecidable-instances  -fglasgow-exts --make -package
haskelldb DBDirect.hs (alos tried  without -lz)

./DBDirect fM mysql "serve
r=localhost db=store uid=marc pwd="
DB/Direct: Daan Leijen (c) 1999, HWT (c) 2003-2004,
           Bjorn Bringert (c) 2005

	   DBDirect: user error (loadShared: couldn't load
	   `/usr/lib/libz.so' because /usr/lib/libz.so: invalid
	    ELF header

What might cause this error?
Do you know how to fix it?
