Build instructions (Windows)

Prerequisites

Windows 7 or later
Visual Studio 2010 Express or Professional, with SP1 update
- Make sure "X64 Compilers and Tools" are installed if you use the Professional edition.
Python 2.7
node.js
git

If you are using Visual Studio 2010 Express then you also need following softwares:

WDK
- Build Environments is required.
Windows 7 SDK
- Windows Headers and Visual C++ Compilers are required.

The instructions below are executed under cygwin, but it's not a requirement, you can also build atom-shell under the Windows command prompt or other terminals.

The building of atom-shell is done entirely with command-line scripts, so you can use any editor you like to develop atom-shell, but it also means you can not use Visual Studio for the development. Support of building with Visual Studio will come in the future.

Note: Even though Visual Studio is not used for building, it's still required because we need the build toolchains it provided.

Getting the code

$ git clone https://github.com/atom/atom-shell.git

Bootstrapping

The bootstrap script will download all necessary build dependencies and create build project files. Notice that we're using ninja to build atom-shell so there is no Visual Studio project generated.

$ cd atom-shell
$ python script/bootstrap.py

Building

Build both Release and Debug targets:

$ python script/build.py

You can also only build the Debug target:

$ python script/build.py -c Debug

After building is done, you can find atom.exe under out\Debug.

64bit support

Currently atom-shell can only be built for 32bit target on Windows, support for 64bit will come in future.

Tests

$ python script/test.py

Troubleshooting

Assertion failed: ((handle))->activecnt >= 0

When building under cygwin, you could see bootstrap.py failed with following error:

Assertion failed: ((handle))->activecnt >= 0, file src\win\pipe.c, line 1430

Traceback (most recent call last):
  File "script/bootstrap.py", line 87, in <module>
    sys.exit(main())
  File "script/bootstrap.py", line 22, in main
    update_node_modules('.')
  File "script/bootstrap.py", line 56, in update_node_modules
    execute([NPM, 'install'])
  File "/home/zcbenz/codes/raven/script/lib/util.py", line 118, in execute
    raise e
subprocess.CalledProcessError: Command '['npm.cmd', 'install']' returned non-zero exit status 3

This is caused by a bug when using cygwin python and win32 node together. The solution is to use the win32 python to execute the bootstrap script (supposing you have installed python under C:\Python27):

/cygdrive/c/Python27/python.exe script/bootstrap.py

LNK1123: failure during conversion to COFF: file invalid or corrupt

Upgrading to VS 2010 SP1 would solve this, read the Microsoft Support article on more of this: http://support.microsoft.com/kb/2757355.
