Hi Smith, I tried the extension with following steps, it works as wish
1. ninja -C out/Debug echo_extension 2. ./out/Debug/xwalk –external-extensions-path=out/Debug/tests/extension/echo_extension xwalk/extension/test/data/index.html I guess it is because you url is not give a html page that access the echo JS api. (Xwalk extension is lazy binding). If still problem, please use –remote-debugging-port=9222 to check whether the js api is exposed. Thanks, Halton. From: Crosswalk-dev [mailto:crosswalk-dev-boun...@lists.crosswalk-project.org] On Behalf Of Smith, Elliot Sent: Friday, January 10, 2014 12:56 AM To: crosswalk-dev@lists.crosswalk-project.org Subject: [Crosswalk-dev] Crosswalk extensions on Tizen I'm attempting to write a Crosswalk extension in C to run on Tizen 2.1.1 on x86. I'm compiling my extension against Crosswalk master and using the latest Crosswalk rpm for Tizen x86 (crosswalk-4.32.67.0-0.i586.rpm). I've put my efforts so far in this repo: https://github.com/townxelliot/xwalk-extension-example There are some instructions in the repo describing the steps I've tried. However, I'm unable to get the extension to load correctly. When I run the application with this command (as root): xwalk --external-extensions-path=/home/developer/extensions-demo/lib/ \ /home/developer/extensions-demo/ (my .so file is in /home/developer/extensions-demo/lib/) I get this output: [0101/022401:INFO:gpu_info_collector_x11.cc(80)] NVCtrl extension does not exist. [0101/022401:ERROR:appcore_context.cc(105)] Failed to get the package: [0101/022401:ERROR:device_capabilities_storage_tizen.cc(78)] Failed to read SD card status [0101/022401:WARNING:proxy_service.cc(890)] PAC support disabled because there is no system implementation [0101/022401:ERROR:unix_domain_socket_util.cc(132)] connect /root/.ecore/elm_indicator_portrait/0: No such file or directory [0101/022401:ERROR:desktop_root_window_host_x11.cc(597)] Not implemented reached in virtual void views::DesktopRootWindowHostX11::SetWindowIcons(const gfx::ImageSkia&, const gfx::ImageSkia&) [0101/022402:INFO:CONSOLE(17)] "Uncaught ReferenceError: echo is not defined", source: app://fmokkgglgnehmmopkkplpimkdmmanchj/index.html (17) The last line suggests the extension hasn't loaded. The application itself does load, and I can see the HTML page. Is there anything obvious I'm missing? Thanks. Elliot -- Elliot Smith Senior Software Engineer Intel Open Source Technology Centre
