Compile Smart_ptr library on Forte (Sun One)

[nobody]

Please support Shared_ptr : Smart_ptr on Sun Solaris  
platform compiling with Forte (Sun One). 

I am unable to link to the checked_deleter method.

Thank you,

This is due to a bug in the Solaris Forte 5.4 compiler. Sun
has it as bug number 4878628. It has trouble properly
instantiating run-time type info for template classes. One
workaround is to explictly instantiate an instance of
boost::checked_deleter<YourClass> in your source code:

// YourClass.cpp
#include <typeinfo>
class YourClass;

namespace
{
  std::type_info const & ti =
    typeid( boost::checked_deleter<YourClass> );
}


Another workaround is to use command-line flags to change
how the C++ compiler generates template instances. One is to
use -instances=global, to give template instances global
linkages (I haven't tested this, it might result in
duplicate symbols).

Another is to use the undocument flags "-Qoption CC
-xcomdat", which switches the compiler to a new, unsupported
linkage mode for templates. This linkage mode will be the
default when SunONE studio 8 is officially released. This
option does work, and makes Sun CC's handling of templates
much better, but is not compatible with some third party
tools such as Purify. YMMV.

If none of these options is acceptable to you, I urge you to
contact your Sun support representative and demand a patch
for bug 4878628 for Sun CC 5.4. It does not appear that Sun
is willing to fix bugs for which there are code workarounds,
unless customers insist.

Hope this helps,
Christopher
