When i looked into boost internal code it is trying to create a folder at ""\tmp\boost_interprocess"" which is not accessible.So to fix this error, i set the path form the application to a global variable in ""os_file_functions.hpp"" to read path in ""boost:interprocess:ipcdetail::get_temporary_path"". But when i tried to include ""os_file_functions.hpp"" in my application at multiple files, it throwing error as ""Multiple definition error"" during linking. Can you please let me know how to fix it. Thanks, Suresh" Support Requests closed To Be Determined interprocess Boost 1.54.0 Problem invalid Multiple definition
