Making interprocess::message_queue use Windows_shared_memory instead of shared_memory_object
by Gaurav Sehgal 04 Oct '18

Hi, I am trying to make boost::interprocess::message_queue to use windows_shared_memory, instead of shared_memory_object. I have made the below changes to boost version 1.65.1 1) In ipc\message_queue.hpp, included windows_shared_memory.hpp instead of shared_memory_object.hpp 2) Changed typedef ipcdetail::managed_open_or_create_impl<shared_memory_object, 0, true, false> open_create_impl_t; to typedef ipcdetail::managed_open_or_create_impl<windows_shared_memory, 0, false, false> open_create_impl_t; 3) Changed the below in mq_hdr_t:: typedef ipcdetail::managed_open_or_create_impl<shared_memory_object, 0, true, false> open_create_impl_t; to typedef ipcdetail::managed_open_or_create_impl<windows_shared_memory, 0, false, false> open_create_impl_t; 4) Changed inline bool message_queue_t<VoidPointer>::remove(const char *name) { return shared_memory_object::remove(name); } to inline bool message_queue_t<VoidPointer>::remove(const char *name) { return true; } 5)Changed the below in detail\managed_open_or_create_impl.hpp template<bool dummy> static void truncate_device(DeviceAbstraction &dev, offset_t size, true_) { dev.truncate(size); } to template<bool dummy> static void truncate_device(DeviceAbstraction &dev, offset_t size, true_) { } After the above changes, no file is getting created and everything seems to work. Is there something else i should care about? Regards, Gaurav.

undefined reference to `boost::log::v2_mt_posix::...

Hello I face this error and I cannot figure out a fix. I use bjam to build the application code, and inside site-config file, I have also the following a section where I define BOOST_ALL_DYN_LINK: ''' using gcc : : : where I have defined <define> BOOST_ALL_DYN_LINK ''' I have build boost libraries with the following command: sudo bjam toolset=gcc --with-system --with-thread --with-timer --with-chrono --with-filesystem --with-program_options --with-timer *--with-log* --with-program_options --with-date_time --with-math --with-serialization --with-regex --with-chrono --with-atomic runtime-link=shared define=*BOOST_ALL_DYN_LINK* --prefix=/opt/boost_shared install | tee output.txt I also changed some files (macro definitions and jam files) because I had an error that system and filesystem are configured to be compiled both as static and shared. I compiled them as shared. When I build the application code, I have plenty of `boost::log::v2_mt_posix::...` error messages. Could you give me some guide why this problem exist? Thanks, Antonis
