The attached e-mail seems to be about a problem using a library compiled with an unregisterised ghc with a registerised ghc. The linking step is giving many "undefined reference to `stg_ap_p_ret'"s (with various numbers of 'p's) as well as a few to `GHCziIOBase_zdWIO_entry', and possible others I didn't spot, while compiling haskelldb with a registerised ghc 6.4.1, where haskelldb depends on hsql, which was compiled with an unregisterised ghc 6.4.1.
Is this expected behaviour? i.e. should I just make sure I don't change which arches are registerised within a GHC version?
If so, would a library compiled with a registerised ghc being used by an unregisterised ghc also cause problems?
That's right - registerised and unregisterised code are completely incompatible. Its similar to the situation with profiled and unprofiled code. Cheers, Simon
