IBM jdk needs kernel patch to fix floating stacks problem? LD_ASSUME_KERNEL

[James Gunning]

Hi ppc'ers
        From discussion on the ibm.software.java.linux newsgroup
---snipped-- below, it's clear
we ppc users need some kernel patch to get the IBM jdk's (1.3.0, 1.3.1)
to work.
Anybody got any  ideas if this is possible? Where to get the patch? Is
there a patch?

Any views welcome,
                                      James.

As I have just posted on another thread:


It looks very much like the floating stack thing.  If YellowDog don't
give you the LD_ASSUME_KERNEL patch, then you can compile
glibc with floating stacks disabled.  This course of action is only open
to the brave and the foolish.
