Building hsdis?

[Ted Neward]

OK, built flawlessly.

Couple of notes:

(*) When I tried to do "make both", as mentioned in the README, it failed in the configure step: "C compiler cannot create executables". This was after "make all64" worked flawlessly. (Both have the BINUTILS variable set via the command-line; I'm eliding it for brevity.)

(*) The Windows part of the build instructions in the README was I think what was confusing, but as an editor, I would probably suggest a bit of reordering/rewording to the parts before that to make it a little easier to grok. Happy to make some suggestions there if desired, but not critical.

(*) Now, how should we proceed trying to build a Windows version of this? The README mentions both Cygwin and Ming, so I'm not sure what setup you're expecting the Windows developer to have on their machine.

    Hi Ted!
    
    No blog to point you to, but building on non-Windows platforms should be 
    pretty painless these days.

    Yes, that is the one to use. The makefile had a number of issues that I 
    fixed recently but have not (yet) backported to 8u-dev.
    
    I was able to build on an Ubuntu 16.4 (AMD64) using the following 
    commands (output omitted):
    
    ===
    hg clone http://hg.openjdk.java.net/jdk/hs
    wget http://ftp.gnu.org/gnu/binutils/binutils-2.28.1.tar.gz
    tar xf binutils-2.28.1.tar.gz
    cd hs/src/utils/hsdis/
    make all64 BINUTILS=../../../../binutils-2.28.1
    ===
    
    The above steps resulted in the plugin being generated here:
    
    hs/src/utils/hsdis/build/linux-amd64/hsdis-amd64.so
    
    Note the version of binutils I used, there is some issue with 2.29 and 
    later versions that prevents the build from succeeding. I hope to 
    investigate if I get some extra bandwidth next year. Also, avoiding 
    "cross compiling" is probably a good idea. If you want to build a 32-bit 
    plugin, it is probably simpler to just build it in a 32-bit environment.
    
    Let us know once you get this working. macOS is pretty similar. Then we 
    can take a crack at a Windows build if you are up for it.
    
    Cheers,
    -Buck

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.
