-Simple Remote Builds
-********************
-
-This tool is an *experimental* tool (meaning, do not even try to pollute
-the waf bug tracker with bugs in here, contact me directly) providing simple
-remote builds.
-
-It uses rsync and ssh to perform the remote builds.
-It is intended for performing cross-compilation on platforms where
-a cross-compiler is either unavailable (eg. MacOS, QNX) a specific product
-does not exist (eg. Windows builds using Visual Studio) or simply not installed.
-This tool sends the sources and the waf script to the remote host,
-and commands the usual waf execution.
-
-There are alternatives to using this tool, such as setting up shared folders,
-logging on to remote machines, and building on the shared folders.
-Electing one method or another depends on the size of the program.
-
-
-Usage
-=====
-
-1. Set your wscript file so it includes a list of variants,
- e.g.::
-
- from waflib import Utils
- top = '.'
- out = 'build'
-
- variants = [
- 'linux_64_debug',
- 'linux_64_release',
- 'linux_32_debug',
- 'linux_32_release',
- ]
-
- from waflib.extras import remote
-
- def options(opt):
- # normal stuff from here on
- opt.load('compiler_c')
-
- def configure(conf):
- if not conf.variant:
- return
- # normal stuff from here on
- conf.load('compiler_c')
-
- def build(bld):
- if not bld.variant:
- return
- # normal stuff from here on
- bld(features='c cprogram', target='app', source='main.c')
-
-
-2. Build the waf file, so it includes this tool, and put it in the current
- directory
-
- .. code:: bash
-
- ./waf-light --tools=remote
-
-3. Set the host names to access the hosts:
-
- .. code:: bash
-
- export REMOTE_QNX=user@kiunix
-
-4. Setup the ssh server and ssh keys
-
- The ssh key should not be protected by a password, or it will prompt for it every time.
- Create the key on the client:
-
- .. code:: bash
-
- ssh-keygen -t rsa -f foo.rsa
-
- Then copy foo.rsa.pub to the remote machine (user@kiunix:/home/user/.ssh/authorized_keys),
- and make sure the permissions are correct (chmod go-w ~ ~/.ssh ~/.ssh/authorized_keys)
-
- A separate key for the build processes can be set in the environment variable WAF_SSH_KEY.
- The tool will then use 'ssh-keyscan' to avoid prompting for remote hosts, so
- be warned to use this feature on internal networks only (MITM).
-
- .. code:: bash
-
- export WAF_SSH_KEY=~/foo.rsa
-
-5. Perform the build:
-
- .. code:: bash
-
- waf configure_all build_all --remote
