together you must specify the -set process_subtype option again to resolve the
ambiguity.
1601 Different values were specified for the process subtype
in <filename> and <filename>; the value given in the -set
process_subtype option was used.
Cause. It is possible to use the
used as eld input, and when you do that you can also use the -set process_subtype
option to assign a numerical subtype to that object file. When eld is then given that
object file in a subsequent link, it copies over the subtype to its output object file again.
However, in the present link, two of the input files had subtypes assigned to them by
previous links, and the numerical values assigned in those previous links were
different, and the present link used the -set process_subtype option to resolve the
ambiguity.
Effect. Warning (eld produces an output file, but it might not be what you intended).
Recovery. If your previous links specified inconsistent process subtypes, and you
didn't intend to do that, you should clean that up. If you do want various object files to
have different process subtypes, and sometimes to be linked together, where you
specify a -set process_subtype option to resolve the ambiguity, then you will have to
live with this warning message about it.
1602 The value given in the -set process_subtype option was
used, but a different value was found in <filename>.
Cause. It is possible to use the
used as eld input, and when you do that you can also use the -set process_subtype
option to assign a numerical subtype to that object file. When eld is then given that
object file in a subsequent link, it copies over the subtype to its output object file again.
However, in the present link, some of the input files had subtypes assigned to them by
previous links, and all those values were the same, but a different value was specified
by a -set process_subtype option in the present link.
Effect. Warning (eld produces an output file, but it might not be what you intended).
Recovery. If there was no need for the input object files to say they had a different
process subtype than what you wanted to specify for the present link, you should clean
that up. If you do want various object files to have process subtypes, and sometimes
to be linked together, where you specify a -set process_subtype option with a value
that doesn't agree with what the input object files said, then you will have to live with
this warning message about it.
1603 Bad input file <filename>; this file is invalid because
the code section named <section name> is larger than 16
megabytes.
