In the project properties, and with the configuration set for All Configurations, go to the "Input" node of the "Linker" properties. Next we need to specify the library to be used. Where the static library's header (StaticLibrarySample.h) is at. "Additional Include Directories" add the directory of the static library project In the top-right is "Configuration" change it to "All Configurations". Under "Configuration properties" expand the "C/C++" node, then select "General". Go to the Solution ExplorerĪnd right-click on the test project, then select "Properties". We need to add the include directory to the project. When the project has been generated, set it as the Startup project. The "Add New Project" window will look something as: Window, keep the defaults we do not want an empty project and we Select "Add" | "New Project.".Ĭreate a Visual C++ Win32 Console Application. To create a program that uses the library, go to the Solution Explorer and right-click on = Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped = Modify the implementation file to be: #include "stdafx.h"īuild will look something as: 1>- Build started: Project: StaticLibrarySample, Configuration: Debug Win32 -ġ> StaticLibrarySample.vcxproj -> C:\Users\Sam\Documents\Visual Studio 2010\Projects\Ĭ-SharpCorner Articles\StaticLibrarySample\Debug\StaticLibrarySample.lib Other C++ features with any functions exposed for use by callers of the static The disadvantage of extern "C" is that it prevents use of classes and Note that the extern "C" makes the function callable by C and by other languagesĪs well. Now modify the header to be as: #pragma once Then do the same to create a cpp file (C++ File (.cpp)), as in:įor most programs, you would add #includes to the stdafx.h file but the details of that Then select "Header File (.h)" as in:īe sure to give the file a name. In the Solution Explorer, right-click on the project and select "Add" | "New Item.". h) and implementation (StaticLibrarySample. We do however need to add a header (StaticLibrarySample. When the project was created, there will be source code files that were generated for the project named stdafx.h, stdafx.cpp and targetver.h. The Win32 Application Wizard will look something as in: You can leave the "Precompiled header" option on. The "Application type" radio button to "Static library". The "Welcome to the Win32 Application Wizard" as in the following: When you do, the first Wizard page will be To create the static library project, start by creating a "Win32 Project". Therefore, to create a static library project, we must create Static libraries are not defined by the C++ language they are a Windows thing.Įach operating system implements static librariesĭifferently, or might not implement them at all. Linked with "C" linkage as described in this article. Languages other than C++ but if that is to be done then the functions must be ![]() It is possible to create a static library that can be called by non-managed The console application will show the details of Therefore we willīegin by creating the project for the static library, then we will create aĬonsole application to test it. General-purpose library used by multiple applications. In this article, I am creating a static library as if it will be a It would then likelyĮxist in a project created for it and a test application would be created for Might be tested using the project that uses it or another project could beĪnother practical use of a static library is as a general-purpose library used by multiple Would probably be created after the project that uses it. Static library is likely used in just the one project and the static library project One practical use of a static library is to splitĪ very large unmanaged project into two or more smaller projects. A static library cannot be usedīy managed (.Net) code directly therefore they are useless for most C# A static library can be used by multiple programs and when it is, it isĬopied into every executable file it is used in. The important thing is that a static library isĬombined with the other code such that everything is put into one executableįile. If you are notįamiliar with link editors then the concept and purposes of link editors Library is linked with the code that uses (calls) it by the link editor. Object files are the output of compilers of unmanaged code and consists of functions that can only be used by unmanaged code. The sample projects in this article were created using Visual Studio 2010.Ī static library consists of object files that are linked together with an exe file. This article shows creation of a static library and how to use a static library using Visual Studio.
