Building hsdis?

[Ted Neward]

Sorry--I was cribbing from here (https://www.chrisnewland.com/building-hsdis-on-linux-amd64-on-debian-369) and it references using 2.23, which memory transposed to 2.32, I think.

I'm not sure what was going wrong (well, I can tell you what the errors were, but I dunno what was causing them), but I want to work from something we know works (a la your instructions) and hopefully that'll catch any environmental differences that might be causing any problems. :-)

The README was a little confusing when I was going through it; I'll try to go back over it tomorrow and try to identify which parts left me confused, in case it's something that needs correcting. (I hold the possibility that I'm just an idiot as a very strong possibility.)

BTW, I'm sure there's a good reason for this, but why doesn't OpenJDK/Oracle offer pre-built versions of hsdis for a variety of common platforms? Is there a licensing issue?

I'll give this a spin tomorrow and fire back with any issues/questions. Thanks!

    Not sure what that is. Latest binutils is 2.29.1.

    That should also work, but I'd still keep things simple and just specify 
    the "all64" make target. As always, whatever is documented in the README 
    file should probably be your default choice.

    No need to clone jdk/hs. I was just cloning it out of habit. All you 
    need is the contents of the hsdir directory (from either repository). 
    There is not much active work done on hsdis, so in practice you are 
    unlikely to notice a difference between the jdk and hs repositories.

Do I need to clone the hs repo on its own? Or can I use the bits buried inside of jdk/src/... (sorry I can't remember the full path off the top of my head)?

I’m trying right now in an Ubuntu 16 VM, but would also want to build on Windows and/or macOS. All the Web is showing me is posts from a few years ago that don’t seem to address some of the issues I’m running into.
