Hi,

The MIPS-specific implementation of shared_ptr with which you're probably 
having problems (contributed by David Joyner in 
https://svn.boost.org/trac/boost/ticket/2885) uses the ll/sc instructions, 
which I guess are not supported by the architecture your compiler defaults 
to (mips1). According to

http://gcc.gnu.org/onlinedocs/gcc-4.5.0/gcc/MIPS-Options.html#MIPS-Options

you probably need to somehow add -mips32r2 to the command line (I'm told 
that virtually all MIPS processors support it).

I found one ticket that matches your situation: 
https://svn.boost.org/trac/boost/ticket/2972, but it's cmake-related and I 
don't know how it was fixed on the cmake side.
