Description Pierre Ossman 2015-02-10 12:25:17 UTC 
Under some circumstances ld can complain that I haven't fulfilled the dependencies of a DSO given on the command line. This is of course absolute nonsense as I should only provide dependencies for my object files, not any DSOs I happen to use.

The complaint is half right though as one of my object files actually needs this library. ld is just not telling me this. This is my link attempt:

Absolutely confusing.

But if I shuffle things around a bit I get at the real reason that things are failing:

Hopefully you can fix this error message so it is easier to figure out what's going on.

Thanks.
