Native Client

Native Client SDK

To build Native Client modules, you must download and install the Native Client Software Development Kit (SDK).

The SDK includes the following:

support for multiple Pepper versions
The SDK contains bundles that let you compile Native Client modules using different versions of the Pepper API (e.g., Pepper 30 or Pepper Canary). Review the Release Notes for a description of the new features included in each Pepper version to help you decide which bundle to use to develop your application. In general, Native Client modules compiled using a particular Pepper version will work in corresponding versions of Chrome and higher. For example, a module compiled using the Pepper 30 platform will work in Chrome 30 and higher.
update utility
The naclsdk utility (naclsdk.bat on Windows) lets you download new bundles that are available, as well as new versions of existing bundles.
Each platform includes three toolchains—one for Portable Native Client (PNaCl) applications, one for compiling architecture-specific Native Client applications with newlib, and a third native NaCl toolchain for compiling with glibc. Newlib and glibc are two different implementations of the C standard library. All toolchains contain Native Client-compatible versions of standard compilers, linkers, and other tools. See this document to help you choose the right toolchain.
Each example in the SDK includes C or C++ source files and header files illustrating how to use NaCl and Pepper, along with a Makefile to build the example using each of the toolchains.
The SDK includes a number of additional tools, which you can use for tasks such as validating Native Client modules and running modules from the command line.

To download and install the SDK, follow the instructions on the Download page.
