linker
linkage editor
link editor
link loader
<programming, tool> (link editor, linkage editor, link loader)
A program that combines one or more files containing {object
code} from separately compiled program {modules} into a single
file containing loadable or executable code
This process involves resolving references between the
{modules} and fixing the {relocation} information used by the
operating system {kernel} when loading the file into memory to
run it.
Under {Unix}, the linker is called "ld" and {object files}
have filename extension .o (object), .so (shared object), or
.lib ({library}), and the resulting {executable} is called
"a.out" by default.
