1. Static link library: It is in the compile time to copy the library code into the project, causing the project to become larger, but faster.The disadvantage is that a set of code may have multiple copies in memory, consuming memory.2. Dynamic link library : Libraries are loaded with library code by the WinDOS API with only one copy in memory. Only references that are linked to this code are retained in th

This paper divides makefile into three parts: generate makefile of executable file, generate makefile of static link library, generate makefile of dynamic link library.These makefile are simple, they are usually used at a glance, and are easy to use, just copy them to the same directory as your code and then use make to generate the target files.Here is the source code for the three makefile:1. Makefile to

The explanation of the static link library is not the focus of this article, but the example of a static link library can quickly help us to establish the concept of "library" before we specifically explain the DLL.

Soft link and hard link details Today, we will introduce the following soft links and hard links. I. What is inode? To understand inode, start with file storage. 1. The file is stored on the hard disk. The minimum storage unit of the hard disk is 512 bytes, which is equivalent to 512 bytes. 2. When the Operating System reads a hard disk, it does not read multiple sectors. This is too inefficient. Instead,
