[Opencryptoki-tech] Re: Alignment problem on AMD opteron to support both 32 and 64 bit apps

[Kent Y. <shp...@gm...>]

Hi Qiyan,

  As long as you compile the project with the -DPKCS64 option, both on
32bit and 64bit platforms, the libraries and daemons should remain
interoperable.  We've tested this on ppc64 and s390x.  Both in 64 and
32bit environments, pkcsslotd will run as a 32bit executable.=20
Originally the -DPKCS64 flag was added to allow us to port to s390x,
but since then, all the platforms we support have a 64bit version, so
we've decided to get rid of the flag.  We have this as an open bug at
the moment, #1106286.

  Our  x86_64 "support" was thrown in as an afterthought.  If you
check out CVS and build and install as normal, you should get
everything installed as it should be, with the exception of the 64bit
libs.  Just apply this patch after the install, run sh bootstrap.sh,
reconfigure and rebuild and you should get the 64bit libs in the right
place.

[Opencryptoki-tech] Users list added

[Kent Y. <shp...@gm...>]

A new list, ope...@li... has been added to the
opencryptoki project.  The list should get all traffic related to the
PKCS#11 API and application development.  opencryptoki-tech will
remain the place for discussion on the internals of the opencryptoki
PKCS#11 implementation itself.

Thanks,
Kent
