[oe] *Very* newbie question: OE and Cygwin?

[Leon Woestenberg]

Jason,

in theory, you might be able to get it (Cygwin + OE) to work. However,
after having spent months to get uClinux working under Cygwin I
*strongly* advice you NOT to use Cygwin for Linux target development.
I wrongly thought this would be the best bet to support my non-Linux
colleagues.

It planned out to be *much* easier to work under Linux, even for the
newbies. Good for them, good for me.

And the fact that your board vendor does use Cygwin (which is bad)
does not count if you want to use OpenEmbedded (which is good),
because OpenEmbedded gives you all you need. I.e. you would not want
to depend on some Linux "release" from your board vendor to build your
application.

The leverage of using Linux pays off on all sides! (test exposure,
build knowledge, build speed, power tools, ....). In fact, I also
consider Cygwin just another "vendor lock in".

These are just my two cents,

Leon.
