[Haskell-cafe] GHC 7.8 undefined symbol

[Sven Bartscher]

Greetings,

I recently installed a library (namely Hpysics, not on hackage) with
shared libraries (they were on by default).
When trying to do some stuff with the library (program attached), I get
a bunch of undefined symbol errors like this:

$ ghc --make Main.hs
Linking Main ...

undefined reference to
`Hpysicszm0zi0_PhysicsziHpysicsziBoundingSphere_zdwlgo_info

Does anyone know, what this is about?

PS: Hpysics can be found at http://code.haskell.org/hpysics/
