[Boost-users] boost shmem

I need to use shared memory in an application on Windows and Solaris so
I've grabbed boost::shmem 0.93. It works fine on Windows but fails to
compile on Solaris 10/SunPro 11. Has anybody had success on Solaris? I
get the following errors when I try to compile.

1 Error(s) and 1 Warning(s) detected.

 

The offending bit of code is:

void sendPathAndName(std::string &path, std::string &name,
boost::shmem::named_shared_object *pSegment)

{

   if(mpPath != NULL)

   {

            pSegment->deallocate(mpPath.get());   // <-- error

   }

 

Where mpPath is a boost::shmem::offset_ptr<char> that was created with
pSegment->allocate()
