Error Messages
parses the contents of the file into “statements”, which in turn can have “attributes”, and
a “dll” statement always contains a “file” attribute, which tells the DLLs name. This
particular message comes out when eld saw two different “dll” statements with the
same name.
Effect. Fatal error (eld immediately stops without creating an output file).
Recovery. If you specified the -public_registry option, are you sure you need to do
that? There usually is no need to give this option, because eld should be able to find
the official version of the public DLL registry automatically. If you specify this option, it
is your responsibility to provide eld with a correct public DLL registry file, and it is
beyond the scope of this manual to describe how this file should be created. If eld
could not find it on its own, and you didn’t specify the -public_registry option, then there
is something wrong with your installation. The message told the name of the file that
eld thought was the public DLL registry file. Perhaps that will help you figure out
what’s wrong.
Cause. The zimpimp file is a file that tells eld about the symbols in system library.
eld has various methods of locating this file. For example, if you are running eld on
TNS/E then the operating system tells eld where the file is. In other cases, eld looks
for it in an appropriate place, expecting it to have the name “zimpimp”. Or, you can
simply put the name of the zimpimp file directly on the eld command line. However,
none of these methods specified a zimpimp file to eld.
Effect. Warning. eld will continue to produce an output file, but it will not be able to
fix up references to system library.
Recovery. It is not necessary to have references fixed up at link time. However,
normally, eld should find a zimpimp file. So, this may indicate that there is something
wrong with your installation. A proper zimpimp file should be built as part of the
process of creating the operating system, and then installed in the proper location for
eld to find it. The process of creating the operating system is beyond the scope of
this manual.
Cause. eld uses the public DLL registry file to look up information about the operating
system and other st
andard DLLs. There are various ways that eld may find this file.
For example, if you are running eld on TNS/E then the operating system tells eld
where the file is. In other cases, eld looks for it in an appropriate place, expecting it to
have the name “zreg”. Or, you can override these methods by explicitly telling eld
where it is with the -public_registry option. However, none of these methods specified
a public DLL registry file to eld.
Effect. Warning. eld will continue to produce an output file, but it will not be able to
fix up references to standard DLLs.
