GNU linker (or GNU ld) is the GNU Project's implementation of the Unix command ld. GNU ld runs the linker, which creates an executable file (or a library) from object files created during compilation of a software project. A linker script may be passed to GNU ld to exercise greater control over the linking process. The GNU linker is part of the GNU Binary Utilities (binutils).
