[Boost-users] Boost conflict with OpenCV, Eigen?

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,
