Output Listings and Error Handling
Cause. You specified the -make_import_lib option, in order to create the zimpimp file
that represents the multiple implicit DLLs that constitute system library, and you also
specified those implicit DLLs on the command line. One of the checks that eld
performs on these implicit DLLs is that they don't have unresolved references, which
would have to be true if that implicit DLL was correctly fixed up at the time it was
linked. But, the implicit DLL mentioned in the message had unresolved references.
Effect. Fatal error (The linker cannot do what was requested of it and the linker
immediately stops).
Recovery. This indicates some problem with the procedure for building and installing
the NSK operating system, which is beyond the scope of this document.
1215 The implicit DLL <filename> has unresolved references.
Cause. You specified the -make_import_lib option, in order to create the zimpimp file
that represents the multiple implicit DLLs that constitute system library, and you also
specified those implicit DLLs on the command line. One of the checks that eld
performs on these implicit DLLs is that they don't have unresolved references, which
would have to be true if that implicit DLL was correctly fixed up at the time it was
linked. But, the implicit DLL mentioned in the message had unresolved references. It
is only a warning message, not an error message, because the -unres_symbols warn
option was also specified.
Effect. Warning (eld produces an output file, but it might not be what you intended).
Recovery. This issue involves the procedure for building and installing the NSK
operating system, which is beyond the scope of this document.
1227 Multiple definition of <symbol name>: first definition
found in <filename>, second definition found in <filename>.
Cause. You specified the -show_multiple_def option, to tell eld to put information into
the listing about symbols that were defined more than once. This message reports the
first two definitions that eld saw for the symbol named in the message.
Effect. Information (This is not indicative of a problem).
Recovery. No action required.
1228 Multiple definition of <symbol name>: third or later
definition found in <filename>.
Cause. You specified the -show_multiple_def option, to tell eld to put information into
the listing about symbols that were defined more than once. There was an instance of
message number 1227 earlier, which reported the first two definitions that eld saw for
