several hours, I did not know why the error occurred. I did not receive any error message when I directly executed the command through command lines. After a long time, I couldn't figure out why, suddenly it may be that the anti-virus software is strange. The reason is that the anti-virus software is a try! This problem was later clarified because anti-virus software may mistakenly think it is a virus for this type of repeatedly registered DLL, so it was blocked! Solution 3: this problem may be

The first two days to understand the dynamic link library and static link library, and finally basically understand that I did not understand the "dlopen" is what happened, how also to take a steak.Shared library, there are two forms, the first is the "Dynamic link library" mentioned in the previous article, and another form of shared library, it is called "Dynam

1.Linux Link ConceptThere are two kinds of Linux links, one is called hard link (Hard link), the other is called Symbolic link (symbolic link). By default, the LN command produces a hard link. "Hard Connection"A hard connection re

The hard link records the inode of the target, and the soft link records the path of the target. Soft links are like shortcuts, while soft links are like backups. Soft links can be used as cross-partition links, while hard links can only be used as links in this partition due to inode, so more soft links are used. Their disadvantages: Hard link: 1. Hard links

Before understanding soft links and hard links, you must first understand some basic concepts.File: file name + DataIn Linux, files are divided into two parts: user data and metadata.User Data: file data block, which is the place where the recorded data is actually stored.Metadata: The append attribute of the stored file (inode node number is stored in the metadata). inode is the unique identifier of the file, not the file name. The file name is just for convenience.Inode: In a Linux file system

. Symbolic connection:Soft link refers to the file path, which is very similar to the shortcut in windows. Differences between symbolic connection and hard connection: A symbolic connection is a path pointing to a file. It does not even need the existence of the original file (this is called a broken link). A hard connection points to the same data zone, which must exist. In addition, hard Connections canno

problem 1 : I created a hard-link file, but I don't know where it is, how do I do it? Ideas: Find files can take advantage of the Find command. hard-link features do not cross the file system, so the source file is in which filesystem, right there. hard-link files and source files have the same inode #, you can use the find -in

There are two kinds of Linux links, one is called hard link (Hard link), the other is called soft link (symbolic link). By default, the LN command produces a hard link. A, [hard link]--> refers to through the index node to connec

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

Before explaining the dynamic link library DLL, let's first explain the static Link Library. The example of a static link library can help us quickly build the concept of "library. Example of a static Link Library First, we use VC ++ to create a static Link Library, use VC

Description of the fs. link Method in node. js, node. jsfs. link Method description: Create a hard link. Syntax: Copy codeThe Code is as follows:Fs. link (srcpath, dstpath, [callback (err)]) Because this method belongs to the fs module, we need to introduce the fs module (var fs = require ("fs") before use ")) Receivin

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.
