I am trying to build boost in Solaris sparc machine, its always produce 32bit libs.

Here is the commend I am using

./bjam --build-dir=$HOME/boost_rel64 --with-thread --with-system --with-date_time --with-random link=shared --stagedir=$HOME/boost_rel64 --layout=tagged link=shared variant=release address-model=64

my compiler version

CC -V

CC: Sun C++ 5.8 2005/10/13

uname -a

SunOS mjnew 5.10 Generic_118833-03 sun4u sparc SUNW,Sun-Fire-V890

How do I produce 64bit libs?

Thanks
