Both of these features are enabled by default. PDFium may be built either with or without JavaScript support, and with or without XFA forms support. Both of these are included with the depot_tools checkout. PDFium uses GN to generate the build files and Ninja to execute the build files. On Linux, additional build dependencies need to be installed by running the following from the pdfium directory./build/install-build-deps.sh This directory must not have been used before by gclient config as each directory can only house a single gclient configuration. In the following example, the directory name is “repo”. The name of the top-level directory does not matter. If you want the IDE for debugging and editing, you will need to install it separately, but this is optional and not needed for building PDFium. The toolchain will be in depot_tools\win_toolchain\vs_files\, and windbg can be found in depot_tools\win_toolchain\vs_files\\win_sdk\Debuggers. Once you've done this, the toolchain will be installed automatically for you in the Generate the build files step below. Note that you must authenticate with your credentials. Run: download_from_google_storage -config and follow the authentication instructions. Bugs and/or patches are welcome, however providing this support is not a priority at this time. It is expected that there are still some places lurking in the code which will not function properly on big-endian architectures. If you specify Android build, the default CPU architecture will be “ arm”. GN parameter “ target_cpu = "x86"” can be used to override the default value. The default architecture for Windows, Linux, and Mac is “ 圆4”. See the platform-specific Chromium build instructions to get started, but replace Chromium's “Get the code” instructions with PDFium's. The availability of the source code will hopefully make it possible for open-source community members to get involved and help complete the Linux port.PDFium uses the same build tooling as Chromium. Our initial Chrome tests have shown us that the browser has serious potential. The V8 engine is highly modular, and could theoretically be used in other contexts as well. During a press briefing today, Google expressed hope that other browsers will adopt V8 to help accelerate the evolution of web applications. The source code of Chrome's high-performance V8 JavaScript engine is also open and available for download. Users will be able to get involved by submitting bug reports too. Google is clearly serious about making sure that Chrome development is sufficiently participatory and inclusive. In addition to providing full access to the source code, Google also offers instructions that explain how to submit patches. The Linux port is still in early stages of development and is not yet fully functional. Detailed build instructions are available for Windows, Linux, and Mac OS X. Google has made the Chrome source available under a permissive BSD license so that it can be incorporated into both open and proprietary software programs. In conjunction with the release, Google has also launched Chromium, an open-source software project that enables third-party developers to study, modify, extend, and redistribute the underlying source code of the Chrome browser. Google has officially released its new Chrome web browser.
