Re: [OMPI devel] RFC: Remove windows support

[Jeff Squyres (jsquyres)]

No other issues were raised about this, and today was the timeout.

On the call today, Ralph volunteered to do the work:

- svn rm the windows-specific components
- remove all the #if Windows-specific code

He'll be doing that over the next week or so.

Thanks Marco - I was hoping that would be the case!

[cut]

2. Remove all Windows code.  This involves some wholesale removing of 
components as well as a bunch of #if code throughout the code base.

   ==> Removing this code can probably be done in multiple SVN commits:

2a. Removing Windows-only components (which, given the rate of change that we 
are planning for the trunk, may well need to be re-written if they are ever 
re-introduced into the tree).


Cygwin does not use them. I'm currently building the trunk packages with

--enable-mca-no-build=paffinity,installdirs-windows,timer-windows,shmem-sysv,if-windows,shmem-windows

to specifically exclude them


2b. Removing "#if WINDOWS" code (e.g., in opal/util/*, etc.).  This code may 
not be changing as much as the rest of the trunk, and may be suitable for svn reverting 
someday.

This does kill Cygwin support, too.  I realize we have a downstream packager 
for Cygwin, but the fact that we can't get any developer support for Windows -- 
despite multiple appeals -- seems to imply that the Windows Open MPI audience 
is very, very small.  So while it feels a bit sad to kill it, it may still be 
the Right Thing to do.


I assume it is __WINDOWS__
That is not defined on cygwin, so the build should survive



This is a proposal, and is open for discussion.
