             Bug #: 15477
           Summary: gld does not understand mapfiles correctly
           Product: binutils
           Version: 2.23
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
        AssignedTo: address@hidden
        ReportedBy: address@hidden
    Classification: Unclassified


gld does not work with typical mapfiles such as used by
e.g.OpenSolaris

To check the problem, get a recent cdrtools tarball from:

ftp://ftp.berlios.de/pub/cdrecord/alpha/ and patch the Linux configuration
to enable map files:

Now chdir into "libschily" and call: "make LINKMODE=dynamic"

This results in:
