Re: Segmentation fault on jRate

[Morgan D. <md...@gm...>]

Hi Angelo and Abdul,

Right, we never did any work on 64-bit.  However, I think I've since
tried jRate on amd64 without serious difficulty (at least of this
sort).  Still, with the kind of hardware-specific tricks we play for
embedded ia32 and ppc, I'm not surprised if we'd have to reengineer a
few things for amd64.

If the need for multilib was detected when jRate was configured, you
have 32-bit jRate libraries.  You can then try compiling
HelloWorld.java with "jRate-gcj -m32 ..." and see if that solves the
segfault problem.  Otherwise, I can recommend recompiling all of jRate
binaries and libraries for 32-bit (with CFLAGS=-m32 at jRate configure
time) and seeing if that works.
