The problem seems to be that when the linker comes to link the expression 'A', it traverses the dependencies graph and doesn't find module `B`. The reason is that the dependencies for module `A` say `C[boot]`, and don't include `B`, despite the fact that `C` depends on `B` (module dependencies are transitively closed, except for `[boot]` dependencies). Perhaps we need to recursively add dependencies for `[boot]` modules that we find? (see `compiler\ghci\Linker.hs:get_deps`). -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/936 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler___ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs

Here is a ghci session with the attached program:

During interactive linking, GHCi couldn't find the following symbol:
B_zdfClass1B_closure
This may be due to you not asking GHCi to load extra object files,
archives or DLLs needed by your current session. Restart GHCi, specifying
the missing library using the -L/path/to/object/dir and -lmissinglibname
flags, or simply by naming the relevant files on the GHCi command line.
Alternatively, this link failure might indicate a bug in GHCi.
If you suspect the latter, please send a bug report to:
glasgow-haskell-bugs@haskell.org
*A B B

*A B A

}}}
3 strange things happen:
1. I ask to load B, it loads C
2. I ask to reload, it loads A :)
3. missing symbol error which goes away after evaluating some other
expression
