by not using the C static keyword). First, create a makefile in the directory where you want your static library to be created, and declare a phony target all whose single prerequisite is the static library. It is a simple example to demonstrate a possible math library. Welcome back to our Embarcadero Dev-C++ videos series. Each source code contains the exported functions. The case scenario is: 1) I have a static library (a .lib file compiled from VC++). // 3 — Make a call for a method that belongs to the library and save the result to a local variable. A static library is basically an archive (like a zip file) of object files, which are compiled from the *.c/*.cpp source code. It will give you the ability to use the code from your library in ViewController. Static libraries are collections of object files that are linked together when a file gets compiled into an executable. In this session is about creating C++ static libraries. You can have one or many classes, and the final build products are the header files and a .a file with the code. 在应用中使用静态库的功能 Use the functionality from the static library in the app. 3) No any dll related to static library. Unlike a static library that generates a monolithic package, a dynamic library must be located appropriately to make sure the executable can find libraries at runtime. Note that the variable rand_seed, because it is not in the header file, cannot be seen or modified by a program using this library. To create a static library project in Visual Studio 2017.

In ‘Advanced Settings’ drop-down menu select ‘Static Library’ as ‘output type’. If you are working in Microsoft Visual Studio, you can start by creating a new project. Building a Static Library 1.2. You can use it in the same project where the library was built or you can use it in another project. We create a static library so that we could reuse all the custom math functions for other programs. In the center pane, select Windows Desktop Wizard. First create a new CCS project: File>New>CCS Project. To demonstrate the static library creation, let us create two C programs — addition.c and multiplication.c. The idea is that these functions are being archived until needed. In this example, we will place the function declaration into libmymath.h . On the menu bar, choose File > New > Project. // 1 — Import Networking library. In this Video Tutorial I have Explained, How to create Static Library in Visual Studio. Compile the C++ code using the header library file using the shared library (using g++) Set LD_LIBRARY_PATH. Give a name to your project ("malibrairie" for instance ), and assign it a destination directory ("C:/essai" for instance ) Delete the default code in the file "main cpp" of the library, and type the following code. // Convert library code to Object file g++ -c -o library.o library.c // Create archive file/ static library ar rcs library.a library.o Archive library is to transfer the library code to the executable so that the executable does not depend on external library dependencies. 5) There are hundreds of functions in the static library. To create a static library you have to use the ‘ar’ or archiver program. Enter the following main program in a file named main.c. To use the library, you would have to reference the library. Just write a .c and .h file and use those in all your projects you want. Static linking is performed at compile time while the dynamic linking is performed at run time by the operating system. An MFC static library is a library file that includes MFC functions or classes. We will have 3 files in this layout. Adding the word static in front of int enforces the hiding completely. This increases the size of the executable. Then, click on finish. To create the static library project, start by creating a "Win32 Project". This feature is not available right now.
