Notes on Atttempt to Port Kaffe 0.10.0 to HP-UX 10.20

[John Gotts]

[I repost this message from John Gotts <jgotts at engin.umich.edu> since it
 bounced, Daniel]

Here are some notes on my unsuccessful quest to port Kaffe 0.10.0 to HP-UX
10.20.  Perhaps someone is willing to continue my quest?

(Please cc: all replies as I don't subscrib e to this list.)

HP-UX 10.x is unsupported in kaffe 0.10.0, but it is possible to get through
the build process.  You need to link all of the shared libraries with "-b -E"
and you need to link the kaffe binary with "-Wl,+s" to enable searching
SHLIB_PATH.  It was a simple matter to edit the relevant autoconf-generated
Makefiles:

You also need to apply the following patch:

...and you need to edit kaffe-0.10.0/config/parisc/threads.h, replacing ? with
1:

 #endif

I chose this number because it's what the SPARC uses, but I have no idea if
it's correct.

Build and install the package.

Add the kaffe bin directory to your path, set your CLASSPATH and KAFFEHOME
environment variables, and instead of setting LD_LIBRARY_PATH, set SHLIB_PATH.

% ./javac
Failed to locate native function:
	java/lang/System.currentTimeMillis()J

./javac[3]: 20412 Abort(coredump)

If you feel like going any further with this, you are on your own.
