Skipping emulator build (for purpose of building on 32-bit hosts)

[Kiran Rao]

According to this thread - since the emulator is moving to 64-bit, it will not longer be possible to build the android source on a 32-bit host.

My requirement is to be able to build just the media framework from a recent branch; and backport it to Android 2.2 or 2.3. I am using a 32-bit (Fedora Core 16) dev machine.

Questions:

1. Can I somehow ignore the emulator part and build the rest of the framework on this 32-bit machine?
2. Or, if I check out the older branches, can I still build all of it on my 32-bit machine? If so, how do I know the latest branch/tag that can be built on a 32-bit host?

You should be able to skip building specific modules by just deleting
them from the source tree (assuming that nothing depends on them). The
emulator is (mostly) in external/qemu.

The last version to officially support 32-bit hosts was Froyo (2.2).
Early versions of Gingerbread didn't work on 32-bit at all, later
versions might have worked experimentally but I'm not sure.

FWIW I recall building froyo on 64 bit hosts.  10.04LTS 64 bit, in fact.

Maybe you should consider using a better tested / supported host OS.

create interesting things.

Froyo definitely builds on 64-bit 10.04. I did such a build not long ago.

I know that Donut doesn't (slight and easily fixable incompatibilities
with gcc 4.4) and was primarily 8.04. I think Eclair might, but my
memory is fuzzy.

Ah, I see. I somehow missed the point that 64-bit has been the official standard since Froyo. Thanks for bringing this to my notice.
