Bug ID: 17952
Summary: confusing undefined reference error message when
mixing DSO and .a (and .o?)
Product: binutils
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: ossman at cendio dot se
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.
