Fork of https://chromium.googlesource.com/native_client/src/native_client with edits to enable building NaCl without the Chromium dev tools. History had to be cut off due to 200 MB zip files in the history. Currently it only works for amd64 host+target. (run.py won't work since NaCl targets aren't supported yet.) Dependencies:

• LLVM (must be installed in /usr/bin)
• SCons

Build the NaCl loader and boostrap loader

scons --mode=opt-host platform=x86-64 sel_ldr

Build the IRT

This requires the Saigo NaCl toolchain. You can provide it by either (a) passing saigo_newlib_dir=<path> on the command line (the directory you want to target is normally called saigo_newlib), or (b) dropping the toolchain in toolchain/linux_x86/ and renaming its top-level directory from saigo_newlib to saigo_newlib_raw.

The following command builds one irt_core_raw.nexe. You need to strip it yourself; ordinary Linux strip seems to work.

scons --mode=nacl saigo=1 platform=x86-64 irt_core_raw [optional saigo_newlib_dir=...]

Try some tests

This builds both components and runs some tests.

scons --mode=opt-host,nacl saigo=1 platform=x86-64 --keep-going small_tests medium_tests

Native Client

Native Client is a deprecated sandboxing technology. It is currently used by a few third party chrome extensions and chrome apps. Many of the original project pages are not longer available. Some documentation can be found at:

• Documentation for contributors to Native Client
• Research papers

Directory structure

The following list describes major files and directories that you'll see in your working copy of the repository, including some directories that don't exist until you've built Native Client. Paths are relative to the native_client directory.

• COPYING NOTICE README.md RELEASE_NOTES documentation/: Documentation, release, and license information.

• SConstruct scons.bat scons scons-out/ site_scons/: Build-related files. The scons.bat and scons files, with data from SConstruct, let you build Native Client and its tests. The scons-out and site-scons directories don't exist in the git repository; they're created when Native Client is built. The scons-out/*/staging directories contain files, such as the Native Client plug-in and compiled examples, that let you use and test Native Client.

• src/: Core source code for Native Client.

• src/include/: Header files that are missing from some platforms and are used by more than one major part of Native Client

• src/shared/: Source code that's used by both trusted code (such as the service runtime) and untrusted code (such as Native Client modules)

• src/third_party: Other people's source code

• src/trusted/: Source code that's used only by trusted code

• src/untrusted/: Source code that's used only by untrusted code

• tests/common/: Source code for examples and tests.

• ../third_party/: Third-party source code and binaries that aren't part of the service runtime. When built, the Native Client toolchain is in src/third_party/nacl_sdk/.

• tools/: Utilities such as the plug-in installer.
