What is a libraryIn essence, a library is a binary form of executable code that can be loaded into memory by the operating system. Because of the different nature of Windows and Linux, the binary of the libraries is incompatible. The library functions supported by Linux operating system are divided into static and dynamic libraries, and dynamic libraries are also called shared libraries. Linux system has se
Android Studio Reference Library project is not difficult, directly add dependent module can, but I have some strange problems during the operation, the bitter disturbance I all day, in order to sacrifice this poor day special mark.First describe my error phenomenon:After the studio configuration is complete, I can't wait to create a project, import the previously used library project (Eclipse Project) into
solution to link library not found when connecting to dynamic link library
When you link to a dynamic library, you may receive an error that cannot find the link library, and if you use the LDD command, you can see all of the dependencies of the executable file. In the "Linux C one-stop programming" book to see some s
IOS Static library, dynamic library and FrameworkThe difference between a static library and a dynamic libraryFirst of all to see what is a library, the library is plainly a compiled binary code, plus a header file can be used by others.When will we use the
When the MFC library and the CRT library conflict, a LNK2005 error occurs. The specific errors are as follows:Nafxcwd.lib (dllmodul.obj): Error LNK2005: [email protected] already defined in LIBCMTD.lib (dllmain.obj)Nafxcwd.lib (afxmem.obj): Error LNK2005: "void * __cdecl operator new (unsigned int)" ([email protected]@z) already defined I n LIBCMTD.lib (new.obj)Nafxcwd.lib (afxmem.obj): Error LNK2005: "Void
1, what is the STM32 function libraryThe above mentioned software library refers to "STM32 standard function library", it is provided by St Company for STM32 function interface, namely API (application program Interface), developers can call these function interfaces to configure the STM32 register, Enables developers to disengage from the lowest register operation;In fact, the
. H header files are required for compilation, Lib is required for linking, and DLL is required for running.
The dependency. Lib is not. dll. If DLL is generated, the Lib file is also generated. If you need to complete source code compilation and linking, it is enough to have header files and Lib. If dynamic connection is also enabled, DLL is enough. In the development and debugging stages, it is best to have both.
. H. Lib. dll:
The role of the H file is to declare the function interface.

I. Description
Similar to the dynamic link library in windows, Linux also has a shared library to support code reuse. *. Dll in windows and *. So in Linux. The following describes how to create and use a Linux shared library.
Ii. Create a shared
The library function not only improves the utilization of the code, but also shields the details of the implementation of the function, and provides a unified interface for different developers. From the perspective of implementation, library functions can be divided into dynamic function libraries and static function libraries. The same set of functions that can be encapsulated into static and dynamic libr
First of all, C + + compilation process
Compile: Check the statement symbol definition, and generate the intermediate language for C + + code translation.
Link: Consolidate intermediate code to generate executable binary code.
Simply put, the library file is a special intermediate language file, the static library is also a special format of the archive file (packaged files).To use a stati
If we pack a static library there must be a need for you to pack a library that can be used on a real machine or on a simulator, and how to package and generate a generic static library.
In fact, it is not difficult, first of all, you need to first through the real machine to generate a real machine can use the static librar

OverviewAs with the C language, the language itself does not provide input and output support, and the input and output are done through a standard library. The standard library of C provides a range of functions that can be used to implement input and output, while the C + + standard library provides a range of classes and objects to perform input and output fun
As a professional programmer, we often create a library of tools because of our work needs. The so-called tool Library is a function library composed of a set of functions, which is pre-compiled for some common problems that are often encountered at work. Typically, the functionality of these libraries is implemented by a series of functions around these data typ
First, preface:In the above, the author systematically expounds the two driving modes of 1602, and simply mentions the Liquidcrystal Library of Arduino. In this article, the following two questions are explored in more depth: how can I minimize the 1602-to-Arduino port footprint? How should the Liquidcrystal library learn? Under the Arduino LCD1602 Comprehensive Study (under), the author intends to introduc
Function libraries are classified into static libraries and dynamic libraries.
The static library will be connected to the target code during program compilation. This static library is no longer needed when the program is running.
The dynamic library is not connected to the target code during program compilation, but is loaded only when the program runs. Theref
Tags: mysqlWhen watching the teaching video of the old boy's teacher, talking about the request from the library to send data from the main library, but think about the rationale, if each time the request from the library to update the data, it can not be updated in real time, for some more "quiet" database is also a waste of resources.After grasping the bag expe
1.Naming rules for static and dynamic libraries in Linux:
Static function library: the static library name is generally libxxx. A. The files generated by static library compilation are large because all the data in the static library will be integrated into the target code.
