Hello, Please can somebody help me on this code (from boost site). I try to run it but I still get the following error: */cygdrive/C/Program Files/NetBeans 7.1.2/ide/bin/nativeexecution/dorun.sh: line 33: 12900 Segmentation fault (core dumped) sh "${SHFILE}" Press [Enter] to close the terminal ...* This is the code for creating vector in shared memory: #include #include #include #include <string> #include <cstdlib> //std::system using namespace boost::interprocess; //Define an STL compatible allocator of ints that allocates from the managed_shared_memory. //This allocator will allow placing containers in the segment typedef allocator ShmemAllocator; //Alias a vector that uses the previous STL-like allocator so that allocates //its values from the segment typedef vector MyVector; //Main function.
