1810,"HP-UX, PA-RISC, GCC 4.1+ sp_counted_base.hpp",Yves Pausch,Peter Dimov,"Hi,
I can't link executables or shared libs 'cause of the following dependency produced by sp_counted_base.hpp and friends:[[BR]]

{{{
/usr/ccs/bin/ld: Unsatisfied symbols:
__sync_fetch_and_add_4 (first referenced in ...) (code)
__sync_val_compare_and_swap_4 (first referenced in ...) (code)
}}}

One can simply reproduce this behavior building this sample:

{{{
#include <boost/shared_ptr.hpp>

int main()
{
        boost::shared_ptr<int> spi ;
}
}}}

I don't know if this is a general solution but for me it helps to patch the mentioned file:[[BR]]

{{{
...
#elif defined(__GNUC__) && ( __GNUC__ * 100 + __GNUC_MINOR__ >= 401 )

# include <boost/detail/sp_counted_base_sync.hpp>
...
}}}

{{{
...
#elif defined(__GNUC__) && ( __GNUC__ * 100 + __GNUC_MINOR__ >= 401 ) && !defined(__hpux)

# include <boost/detail/sp_counted_base_sync.hpp>
...
}}}
After that, the compiler passes BOOST_HAS_PTHREADS section and includes sp_counted_base_pt.hpp which works.[[BR]]

Thanks for considering to solve this issue.[[BR]]
