Re: [pde-build-dev] Default for target windowing system

[Andrew Niefer <aniefer@xxxxxxxxxx>]

There is no way to influence the guess,
only to set the value so that the guess isn't made.

In addition to the command line, you
can also set the system properties osgi.os, osgi.ws, osgi.arch, which I
think could be done in the config.ini as well as vm arguments.

The guesses are made by the EnvironmentInfo
service, which is provided by the EclipseAdapterHook and EclipseEnvironmentInfo.
 It might be possible to provide your own framework extension with
an AdapterHook to do this.  However, this is beyond what I know so
I wouldnt be help there.

See http://wiki.eclipse.org/Adaptor_Hooks.

Subject	Re: [pde-build-dev] Default for target windowing system

Hi Andrew,
Buckminster headless is an equinox app. It's invoked using Java so the
binary launcher is never used. We don't include a binary launcher in our
product since it's essential that it platform agnostic. So that leaves
"Guessed by OSGi". Is there anyway to influence that guess (in
a generic 
sense, i.e. provide new defaults based on OS/Arch)?

Regards,
Thomas Hallgren
