Statically Linked Binaries
A binary is another word for a program or “executable”.
By statically linked I mean that the binary doesn’t require any shared libraries (DLLs under windows) to run - any library code has been “statically linked” directly into the binary. This makes the binary a little larger probably - which might seem bad but in practice it’s great for hassle free support of your customers since there is no problem with not having the right DLL to run the program.
