Boost version: 1.55.0 OS: Windows 8 IDE: Visual Studio 2010 Boost Module: Boost Log I'm using Boost Logging in my C++ application. I have been able to generate log of this format [2014-Jul-15 10:47:26.137959]: <debug> A regular message I want to be able to add source file name and line number where the log is generated, But i'm not able to do so.
