             Bug #: 14852
           Summary: gnu ld can't use a library linked via solaris ld, if
                    that library uses a library linked with GNU ld
           Product: binutils
           Version: 2.22
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
        AssignedTo: address@hidden
        ReportedBy: address@hidden
    Classification: Unclassified

test suite and binaries

Suppose we have a library [number 1] linked with GNU ld, say libz.
Then we use this library (libz) to create other library [number 2]
(e. g. libzfs), but using illumos/solaris link-editor.
Then if we try to link libzfs to some application using
GNU ld we will fail. Error will look like:

"undefined reference to address@hidden'"

This is because symbol `compress' in libz has no version assosiated, and thus
is of "base version" which is the soname. Default and hardcoded behavior of
solaris link-editor is to import base versions into outputfile (I quess it is
like the option --default-imported-symver for GNU ld).

I'd rather think it's solaris linker bug (a kind of), but it looks more tricky,
because solaris linker can use library number 2 without any issues.

I'm attaching an archive with tests and precompiled libraries.

Note, that GNU ld I use is patched to support alternative linker, and
ld-gnu-to-sun is a wrapper for solaris ld.
