hello, everyone:

 

    I¡¯m a newbie to boost::interprocess, It¡¯s really a cool library,

so I try to write a simple program to test mapped file, it¡¯s really

simple:

 

#include <boost/interprocess/managed_mapped_file.hpp>

using namespace boost::interprocess;

 

int main()

{

    managed_mapped_file mfile(open_or_create,

                                 "/home/fractal/log.bin",

                                1024);    //hanging here.

    return 0;

}

 

but it¡¯s hanging on the creation of mapped file, I test it both on

ubuntu 11.05(in virtualbox) and openSuse, the same problem remain.

I¡¯m sure the file exists, and I traced down the source code, it seems

the program stuck in a while loop in function priv_open_or_create(...).

 

except that, if I set the third argument of constructor from 1024 to 1,

it¡¯s even throw a exception( not good).

 

any seggestion is appreciated!!!
