Hello,<div><br></div><div>I&#39;m upgrading my code from 1.42 to 1.49. Eventually I will upgrade from filesystem v2 to v3, but for now I&#39;m stuck using v2. I noticed during my recompilation that code using filesystem no longer compiles unless I specify both the -lboost_filesystem and -lboost_system linker arguments; previously I only had to provide the -lboost_filesystem argument. I&#39;m using g++ 4.6.2 on rhel6. I verified this by attempting to compile the file_size example that comes with boost. I was wondering if this is a necessary change due to the differences between 1.42 and 1.49 or if I&#39;m doing something incorrectly. </div>
