MS Windows machine?

Anyone tried to cross-compile for MS Windows target with Yocto/OE?

Yes, see meta-mingw.

A misunderstanding?

I like to build *for* MS Windows, not *at* MS Windows.

"OpenEmbedded meta layer for mingw based SDKs"

Running bitbake on Windows isn't possible.  It's getting closer with the
new Subsystem for Linux thing but that's not ready yet.

meta-mingw lets you build SDKs *for* Windows.  We've used it to build cross
compilers that run on Windows that generate Linux binaries.

If you want to build for a Windows target then that should be possible but
nobody as far as I'm aware has made the work public.  meta-mingw will
contain most of the changes needed as that does build Windows binaries.

That's exactly what we like to to.

So has anyone tried this before?

What else would be needed to build e.g. for MACHINE=i686-mingw32?

Is someone able to create a machine definition for this? I'm not really familiar with this job.

In basic terms, you need a machine which:

* Sets TARGET_ARCH to the right thing (i686 or x86_64)
* Sets TARGET_OS to mingw32

and then some distro config which sets up the toolchain when mingw is
the target os to the values like meta-mingw/conf/machine-sdk/i686-
mingw32.conf sets.

You'd need need to look through the bbappends which are in meta-mingw
and add them to the appropriate pieces you need for target binaries
rather than sdk binaries.

I did once do this for darwin so it is possible, I've never tried it
for windows though.

Cheers,

Richard

Do you have a sample distro config which we can use as a template?

No, sorry. As I said, I've not tried this before. Its not a trivial
thing to do, equally it shouldn't be too bad given what we already
have...

Sadly I don't have the time available to play with something like that
either, much as I do quite enjoy it...

Cheers,
