 Other Linux distros are not supported (as of 8/2014). While it is possible to compile the Dart SDK, compiling Dartium is a lot harder and it is harder to debug without Dartium.  Other Linux distros are not officially supported.

   There is an unofficial PPA to install it on Ubuntu:

 Once Dart Editor is started, the directories \texttt{loncapa/modules/damieng/graphical_editor/daxe} and \texttt{loncapa/modules/damieng/graphical_editor/loncapa\_daxe} should be opened with the menu \texttt{File-Open existing Folder...}. They will reopen automatically the next time Dart Editor is opened.  Once Dart Editor is started, the directories \texttt{loncapa/modules/damieng/graphical_editor/daxe} and \texttt{loncapa/modules/damieng/graphical_editor/loncapa\_daxe} should be opened with the menu \texttt{File-Open existing Folder...}.

   For JSME to work, it should be uncompressed from \texttt{loncapa\_daxe/JSME_2015-03-03_xsiframe.zip}, and the \texttt{jsme} directory should be moved to \texttt{loncapa\_daxe/web}.
   
 Note that was a bug in the Dart SDK 1.5 that prevented the use of Daxe in Javascript (Dart Issue 19888). It is fixed in v1.6. Since early 2013 (before version 1), there has been some issues with the conversion from Dart to Javascript, but Google has been fast to fix them when they were reported at \url{https://code.google.com/p/dart/issues/list}.  Note that was a bug in the Dart SDK 1.5 that prevented the use of Daxe in Javascript (Dart Issue 19888).

 Note that an export is not necessary to just test Daxe with Javascript (as explained above).  Note that an export is not necessary to just test Daxe with Javascript (it can be done with Dart Editor, as explained above).
 To export the Javascript code and related files for use in LON-CAPA, select a LON-CAPA Daxe file (as opposed to Daxe) in the Dart editor,  
 and select the menu \texttt{Tools - Pub Build (generates JS)}. A whole directory is built in \texttt{loncapa\_daxe/build}.  To export the minimized Javascript code and related files for use in LON-CAPA, use the \texttt{loncapa\_daxe/build.sh} script. It creates a \texttt{dist} directory with everything needed to run LON-CAPA Daxe in any web browser. Note that depending on the browser, it might not work with "file://" URLs (because of security restrictions), so the contents have to be put on a web server first.
 This does not create a directory with a minimal set of files. \texttt{loncapa\_daxe/build.sh} can be used for that.
