Hi there,

I have a program that uses Filesystem, which compiles and runs without problem, but only if used by itself.
If I use Filesystem within a program that also needs OpenCV and Eigen libraries, there seems to be a conflict:
...

etc.

Are there known conflicts between Boost (1.45) and OpenCV 2.2/Eigen2/other libraries? I am using Eclipse CDT and MinGW toolchain. After going through problems described in http://boost.2283326.n4.nabble.com/How-to-built-boost-td3053130.html, my Filesystem library is of version 3, whereas other ones are of version 2.

Cheers,
