Linking Files Linker Command Line

COMMAND LINE SPECIFICATIONS

The following rules govern the command line specification:

• ZLD examines the named files’ content to determine the file type (object, library, or

command).

• The file names of the input files specified on the command line must be separated by

spaces or tabs.

• The commands are not case sensitive; however, command line options and symbol

names are case sensitive.

• The order of specifying options does not matter.

• The options must appear before the filenames.

• Specifying that input files use both command line and list creates a union of the two sets

of inputs that is treated as input object and library files. The linker links the file twice,

if the file names appear twice.

• During linking, the linker combines all object files in the order specified and resolves

the external references. linker searches through the library files when it is unable to

resolve references.

• A command file is a text file containing linker commands and options. Comments can

be specified by use of the “;” character.

• If the linker is unable to open a named object file, library file, or a link command file,

an error message is written to the standard error device, and the linker terminates

without linking anything.

• If an unsupported OMF type of object file is included in the <filename> list, the linker

displays an error message and terminates without linking anything.
