Hi, When bcp is searching for files to copy, it doesn't normalize the path, so if a file is referenced from two different locations using relative paths it doesn't work. This happens when it is used on the preprocessor library. The following patch fixes this by normalizing the path in bcp_implementation::add_path. It also updates bcp's Jamfile.v2.
