[OpenIndiana-discuss] 32-bit support in OpenIndiana Hipster

Hmm could we instead have binaries delivered in respective /usr/bin/$ARCH
and use isaexec ?
Or at least not mix 32 and 64 bits in /usr/bin ?
That's what I had in mind when I talked about modifying some macros...

Sure. It do not think it can be otherwise.

OmniOS and Dilos already doesn't claim to support 64-bit binaries. Dilos I

Default paths for executables as defined for instance in configure.mk.

OK

OK.

But should we call for finishing the migration of consolidations first ?
Then we could at least tag oi-userland to a state where it can be used to
produce a working system.

If you set a deadline, the next snapshot could then be a proper milestone.
I generated all the Makefiles containing metadata for x11 so that even
someone not used to oi-userland could clone my x11 branch, copy the
Makefile modify it to pass the install target and generate a manifest: even
just passing prep would save time.

There are about 120 packages left, most of them easy, so it is really about
pushing for it (I know, easier said than done).
I prepared a quick start tutorial for oi-userland that can be used.

Thank you for your answers.
We should put up a Wiki page to explain that. I know it takes time but that
would reduce the risk of misunderstanding.
