Hi, I am trying to create a shared memory segment where I can share a STRING between 2 process, I tried using the following code: *In the "main" process:* #include <boost/interprocess/managed_shared_memory.hpp> #include <boost/interprocess/containers/vector.hpp> #include <boost/interprocess/allocators/allocator.hpp> #include <cstdlib> #include <string> #include <iostream> using namespace boost::interprocess; typedef allocator<std::string, managed_shared_memory::segment_manager> ShMemAllocator; typedef vector<std::string, ShMemAllocator> MyVector; int main(int argc, char** argv) { struct shm_remove { shm_remove() {shared_memory_object::remove("MySharedMemory"); } ~shm_remove() {shared_memory_object::remove("MySharedMemory"); } }remover; managed_shared_memory segment(create_only, "MySharedMemory", 65536); const ShMemAllocator alloc_inst(segment.get_segment_manager()); MyVector *myVector = segment.construct<MyVector>("MyVector" )(alloc_inst); myVector->push_back("a"); int stop; //this line helps me wait until i run the other process std::cin >> stop; return (EXIT_SUCCESS); } *at the "client" process:* #include <boost/interprocess/managed_shared_memory.hpp> #include <boost/interprocess/containers/vector.hpp> #include <boost/interprocess/allocators/allocator.hpp> #include <cstdlib> #include <string> #include <iostream> using namespace boost::interprocess; typedef allocator<std::string, managed_shared_memory::segment_manager> ShMemAllocator; typedef vector<std::string, ShMemAllocator> MyVector; int main(int argc, char** argv) { managed_shared_memory segment(open_only, "MySharedMemory"); MyVector *myVector = segment.find<MyVector>("MyVector").first; std::cout << "myVector size: " << myVector->at(0) << std::endl; return (EXIT_SUCCESS); } When I run both I receive an error "Segmentation Fault, Core Dumped"... Does anyone know how to solve this? Thanks Dann
