I'm trying to build the toolchain using Cygwin in Windows, however I'm getting various errors. Is there documentation on getting this to work?
There is currently no method to build the toolchain under Cygwin and we don't plan to support this in the future.
As an alternative, you may want to consider installing coLinux in Windows, as this should allow you to run Linux "cooperatively" alongside Windows.
The website is available here:
you don't want to direct people to the upstream coLinux site. better to point them here:
there people can find an installer that configures coLinux for them automatically (which upstream does not provide).
