Universal C Runtime Windows 8 Install This Update
The Standard C Library, POSIX extensions and Microsoft-specific functions, macros, and global variables were moved into a new library, the Universal C Runtime Library (Universal CRT or UCRT). In Visual Studio 2015, the Microsoft C Runtime Library (CRT) was refactored. Before you install this update, check out. Update for Windows 8 for x64-based Systems (KB2999226) Bulletin Id: MSWU-1556: Bulletin Title: Update for Universal C RunTime in Windows (2999226) Severity: Unrated: Location Path: Windows8-RT-KB2999226-x64.msu: Bulletin Summary: This article describes an update for Universal C RunTime (CRT) in Windows.
The UCRT supports a stable ABI based on C calling conventions, and it conforms closely to the ISO C99 standard, with only a few exceptions. File Name:The UCRT is now a Windows component, and ships as part of Windows 10. The Windows Update package on this page allows Windows desktop applications that depend on the Windows 10 Universal CRT release to run on Windows Vista SP2, Windows 7 SP1, Windows 8, and Windows 8.1 S14. With this, edition 24, The Last Post continues to deliver news.The Windows 10 Universal C Runtime (CRT) is a Windows operating system component.
Universal C Runtime Windows 8 Software Development Kit
The Visual Studio installer adds the locations of the UCRT headers, libraries and DLL files to the default paths used by the Visual Studio project build system. When you install Visual Studio, the parts of the Windows SDK required to use the UCRT are also installed. Where to find the Universal CRT filesAs a Windows component, the UCRT library files and headers are now part of the Windows software development kit (SDK). To take advantage of these changes, your existing code and project build systems must be updated. In addition, many functions and macros in the UCRT were added or changed to improve standards conformance.
Debug UCRT libraries are not redistributable, and can be found in the Program Files or Program Files (x86) directory under Windows Kits\10\bin\ architecture\ucrt folder.The C and C++ compiler-specific runtime support library, vcruntime, contains the code required to support program startup and features such as exception handling and intrinsics. The retail DLLs are redistributable, and can be found in the Program Files or Program Files (x86) directory under Windows Kits\10\Redist\ucrt\DLLs\ architecture. The retail and debug static libraries are libucrt.lib and libucrtd.lib, and the libraries for the UCRT DLLs are ucrt.lib and ucrtd.lib.The retail and debug UCRT DLLs are found in separate locations. A typical location for the header files is in the Program Files or Program Files (x86) directory under Windows Kits\10\Include\ sdk-version\ucrt, where sdk-version corresponds to a Windows version or update, for example, 3.0 for the Anniversary Update of Windows 10.The UCRT static libraries and dynamic link stub libraries are found in the Program Files or Program Files (x86) directory under Windows Kits\10\Lib\ sdk-version\ucrt\ architecture, where architecture is ARM, x86, or X64. Similarly, if you use a Developer command prompt to do command-line builds, the environment variables that contain paths for headers and libraries are updated and work automatically as well.The Standard C Library header files are now found in the Windows SDK in an include folder in an SDK version-specific directory.
The dynamic link retail and debug stub libraries are vcruntime.lib and vcruntimed.lib, respectively.When you update your Visual Studio C++ projects, if you have set the project's Linker property Ignore All Default Libraries to Yes or if you use the /NODEFAULTLIB linker option on the command line, then you must update your list of libraries to include the new, refactored libraries. The retail and debug versions of the static library are libvcruntime.lib and libvcruntimed.lib. Link libraries for OneCore and Store are also found in the libraries folder. In Visual Studio 2017, the headers are found under Microsoft Visual Studio\2017\ edition\VC\Tools\MSVC\ lib-version\include and the link libraries are found under Microsoft Visual Studio\2017\ edition\VC\Tools\MSVC\ lib-version\lib\ architecture, where edition is the edition of Visual Studio installed, lib-version is the version of the libraries, and architecture is the processor architecture.
You can redistribute it using a vcredist package for supported versions of Windows other than Windows 10. Because the UCRT is a Windows component, for security and ease of updates, and a smaller image size, we strongly recommend central deployment of the UCRT for your app.You can use the UCRT on any version of Windows supported by Visual Studio 2015 or Visual Studio 2017. As an operating system component, UCRT updates and servicing are managed by Windows Update independently of Visual Studio and Microsoft C++ compiler versions. A redistributable version is available for Windows XP. Deployment and redistribution of the Universal CRTBecause the UCRT is now a Microsoft Windows operating system component, it is included as part of the operating system in Windows 10 and is available through Windows Update for older operating systems, Windows Vista through Windows 8.1. For information on the specific libraries to use, see CRT Library Features.
It includes a list of affected headers and functions that you can use to identify the changes needed in your code. For a detailed listing of the breaking changes and updates to the CRT found in the Universal CRT, see the C Runtime Library (CRT) section of the Visual C++ change history. If your code compiled cleanly when using an older version of the CRT but breaks when compiled using the UCRT, you must change your code to take advantage of these updates and features. In some cases, this required breaking changes to the library.
