How to see, download, and build the Dart source code

Updated Oct 25, 2011 by iposva@google.com

This page tells you how to get and build the Dart source code. You can also browse the repository or list the changes.

If your machine is already set up to build Chromium, then you should have all the prerequisites for building Dart. Otherwise prepare your machine according to these instructions: PreparingYourMachine.

Getting the source

Create a directory into which you want to checkout the Dart sources and change into that directory.

Getting everything

gclient config http://dart.googlecode.com/svn/trunk/deps/all.deps
gclient sync

For instructions on how to build and test, refer to Building everything.

Getting the standalone VM

gclient config http://dart.googlecode.com/svn/trunk/deps/standalone.deps
gclient sync

For instructions on how to build and test, refer to Building the standalone VM.

Attention Committers:

For all instructions above, use https instead of http, and replace trunk with branches/bleeding_edge or use the instructions from the Contributing wiki page. Also use your Google Code password when prompted.

Any suggestions on how to cure this?

gclient config http://dart.googlecode.com/svn/trunk/deps/standalone.deps gclient sync

On CentOS 5.7 I had to build a local copy of Python 2.7.2 to get gclient working. The default version installed (2.4.3) was causing the following error:

Traceback (most recent call last):
  File "/home/andy/code/depot_tools/gclient.py", line 68, in ?
    import gclient_scm

Re: DumpRenderTree?- I followed the instructions on the console and the problem was resolved

Sync will fail on windows as of today. To work around, see issue 109 .

Re: DumpRenderTree? -- I encountered the same problem. In my case here is no gsutil directory in third_party. I have the following

init.py pymox repo simplejson upload.py

Any ideas on how to move forward?

Comment by sta...@gmail.com, Nov 23, 2011

Re: Above

sudo apt-get install gsutil

gclient sync
