Getting JDK 1.2 to work under glibc 2.1

Getting JDK 1.2 to work under glibc 2.1

[Kevin B. Hendricks]

Hi,

As my last act before I move my family to Canada and spend all of my time
packing and unpacking, I was trying to get a glibc 2.1 version of JDK 1.2
available for release.  Since linuxppc R5 has no cd yet, I bought the
yellowdog linux distribution and installed it on my home machine.

I was able to get JDK 1.2 to build under glibc 2.1 using this distribution,
but every time I try to invoke the JVM it seg-faults.  The seg-faults occur
inside glibc 2.1 (in stderr@@GLIBC2.0) during linking.  It seems whenever
the linker can't find a symbol it seems to end is a seg-fault?  Is this a
known problem?

FWIW, this same code works perfectly under glibc 1.99 (Gary's) and works
fine under glibc 2.1 on Linux x86 (or so I am told).

This is with glibc 2.1-1a.ppc.rpm that comes with the yellowdog glibc 2.1
cd distribution.

Is this a known problem with glibc 2.1? Is this a ppc specific problem?

What is the most up-to-date glibc 2.1 rpm that I can use to build with?

Will any JDK 1.2 which works with Yellow Dog Linux work with Linux PPC R5?

I don't have much time and I want to get something out (JDK wise) in the
next week or so if possible before I have to pack my machines up.

Thanks for any help or guidance.

Kevin

Don't remember anything like that.

get the just released stuff from DRR1, the usual packages, they will install
nicely on YDL:
binutils*
egcs*
libstdc++*
cpp*
glibc*
nscd*

If this doesn't help, more information on the segfault would be good (I know
it's hard to get it :-( ).

Franz.

Hi Tom and Franz,

Thanks!  I upgraded the tool chain to DRR1 and that did the trick.  So I
now have JDK 1.2 up and running under glibc 2.1.  I still have alot of
testing to do of both Motif 2.1 and the JDK but I think I am pretty much
there.

Hi Everyone,

What I need now is a volunteer using glibc 2.1 to put the JDK 1.2 through
its paces and test it as completely as they can.  My home machine is
isolated and I have run the usual few tests I have access to, but I would
really like someone to put it through the ringer under glibc 2.1 and let me
know how it holds up.

If anyone is truly interested and has the time over the next week or so to
pound on it, I would be happy to privately post a beta version for them to
test (please only if interested and serious about testing).  Once it has
been tested, I will make a formal release (hopefully by the end of next
week).

Thanks,

Kevin
