Linker Command Files
7-22
Example
7–1 shows a sample linker command file called link.cmd.
(Subsection 2.4.2,
Placing Sections in the Memory Map, on page 2-14 con-
tains another example of a linker command file.)
Example 7–1. Linker Command File
a.obj /* First input filename */
b.obj /* Second input filename */
–o prog.out /* Option to specify output file */
–m prog.map /* Option to specify map file */
The sample file in Example 7–1 contains only filenames and options. You can
place comments in a command file by delimiting them with /* and */. To invoke
the linker with this command file, enter:
lnk500
link.cmd
You can place other parameters on the command line when you use a
command file:
lnk500
–r link.cmd c.obj d.obj
The linker processes the command file as soon as it encounters it, so a.obj and
b.obj are linked into the output module before c.obj and d.obj.
You can specify multiple command files. If, for example, you have a file called
names.lst that contains filenames and another file called dir.cmd that contains
linker directives, you could enter:
lnk500
names.lst dir.cmd
One command file can call another command file; this type of nesting is limited
to 16 levels. If a command file calls another command file as input, this
statement must be the
last statement in the calling command file.
