Linker is a program that takes object files generated by a compiler and combines them into a single executable file, library, or another 'output' file. It resolves symbolic references between object files and assigns final addresses to create an executable program.

How to use it in a sentence

• I finished writing my C++ code, but when I ran the linker, it threw a bunch of cryptic errors about undefined symbols. I guess I'll be spending my afternoon deciphering linker-speak instead of getting any real work done.

• The junior dev couldn't figure out why his code wouldn't compile, so I had to explain to him that he was missing a library and the linker couldn't find the references. These kids think everything magically works like in JavaScript land.

• Let the Other 95% of Great Programmers In: This essay argues for the importance of making programming more accessible, using powerful languages like Lisp. It touches on how linkers and other low-level tools can be barriers to entry.

• Lisp for Web-Based Applications: Graham discusses the advantages of using Lisp for web development, including its simplicity and flexibility. Understanding linkers and other build tools is less critical in Lisp's interactive development environment.

• Redundancy and Power: This article explores the trade-offs between redundancy and power in programming languages. Lower-level languages with manual memory management and linker scripts offer more control but also more complexity compared to higher-level, "redundant" languages.
