[Scons-users] Adding new platforms

[Kenny, Jason L]

I will let Gary talk about his thoughts…

In Parts extension to SCons I have added an API to deal with this. We have a notion of a SystemPlatform object that you can extend. We do this at my day job as we need to add stuff for the PHI ( K1OM) cards and we needed to view BSD differently from linux as a build platform. If what I have in Parts  is useful for you can extend it with a custom platform. There is an API that you would call to add information about new platform.   The trick is that you will have to use HOST_PLATFORM or TARGET_PLATFORM to get at these values as I did not want to overwrite the SCons PLATFORM value

I think its still mostly design phase or prototyping.  Gary his the most insight.

Hi Bill -

Is there an overview of what is in the works? I would be very interested in understanding what is coming up, as this has been an area of ongoing concern and difficulty for the project I work on.

Thanks,
Andrew

There's a revamp of tools/platform support in the works. Though it may take a while to complete.
Currently the logic which defines which tools on which platforms is not well segregated.

I would also be interested in an answer to this question. Is there any way I can define a new platform? Ideally it would be a file in my site_scons.

Thanks,
Andrew

Since I work in a cross-development environment, I would like to add a new 'platform' complete with its 'tools' corresponding to each target architecture, such that I can say

     env =  Environment (platform = 'my_target_platform')

in much the same way you can say

    env = Environment (platform = 'os2')

I can generate the platform specification and even get it generated, however, I am stymied being able to 'register' the platform by name.  I glanced over the code that SCons uses, but this seems to assume that one is getting the 'platform' from a Python package of that name contained in the Platform subdirectory of SCons.   While perhaps I could put my stuff there, I would rather not modify the SCons source code in anyway.

To some extent, I realize this is syntactical sugar, but it makes accessing the cross-development platforms uniform.

Suggestions?
