On thing to think about (which I didn't realize until now) is that HDK should sit above /classlib in the tree right? the VMs will need it as well. I imagine :

enhanced/
    classlib/
    drlvm/
    jchevm/
    bootvm/

So maybe add a

   enhanced/common

directory in which the HDK sits by default?

I'd like to avoid the structural balkanization of making classlib an island.

I had imagined that HDKs would be packaged up as zips and made available in a similar way to snapshots, rather than having a tree of binaries checked into SVN.

I think we all did. I don't know what about the above leads you to assume I would have wanted this in SVN.

I think I'm just easily confused ;)
So are you suggesting that the HDK should sit in a concrete location
relative to whichever component (VM/classlib) we are working on, or
that the HDK zips should be stored in SVN? (or something else...?)

I think that the HDK should be a zip/tar that you download from our distro locations(s), and dropped into

a) a well-known default location

b) anywhere you want so you can set a pointer if you have more than one

and no, they aren't stored in SVN.

Sounds good!






IMHO keeping it as a zip makes unpacking it where you want very simple, allows you to easily keep a "known good" HDK configuration locally (in the form of the original zip) and makes it very easy to get previous versions of
the HDK (just download an earlier zip).
I'd be interested to hear what general consensus on this matter is, and
how mailing list members would prefer the HDK to be provided.

Keeping zips around and all that is great, but is it that Eclipse would break having it up and above the root of the project tree?

I dont see this as a problem.
If you use the Ant scripts to build (which can be used within Eclipse), then an hy.hdk property (described in one of my other mails in this thread) that
can be set to point at an HDK will enable you to use any location.
If you wanted to work on Java code as a Java project under Eclipse,
then you should only have to point Eclipse at the jre under your HDK
and Eclipse will build against it.

Cool

We discussed [1] that having separate HDKs for each VM and for classlib makes sense - as long as we keep them in a uniform shape, then they can easily overlaid onto each other to allow a developer to work on the classlib and the
VM of their choice.
I don't see this separation of classlib and VMs as a bad thing. I think that having a VMI enabling us to develop the classlib and VMs as distinct units, and developing using potentially disparate methods and build systems that
most suit that component, is one of the cool things about Harmony!

Hi all,

I have opened HARMONY-485, which proposes an additional doc for the website describing the HDK and its contents. The layout of the HDK described in the doc matches that produced by the build script alterations raised in
HARMONY-469.

I hope that eventually (once the natives are modularised
and build scripts are altered to understand/use the HDK) the doc will expand into a more full description of how developers can use the HDK to rebuild Java/native code.

Regards,
Oliver
