Please ignore my previous message, I was compiling with -DYNAMIC instead of -dynamic On Sat, May 31, 2014 at 12:39 PM, GHC wrote:

Comment (by George):

Replying to [comment:4 simonpj]:

...

Summarising the behaviour. If you say `:load Foo` in GHCi * `Foo` was compiled with `-dynamic`: loads `Foo.o` * `Foo` was compiled without any dynamic flag: does not find object files, so interprets. * `Foo` was compiled with `-dynamic-too`: fails as above.

Not a release blocker.

The first case

...

* `Foo` was compiled with `-dynamic`: loads `Foo.o`

does not seem to be the case in 7.8.2, at least on the Mac where the .o file does not get loaded

Should I file a bug?
