Hi,
Here is what I get when I try to link my unit tests agains
boost_date_time.

Libraries should be listed (with the -l option) in "ascending order of use", that is, if library A uses library B, then library B should be listed after A. The error message says that libfxoverlayBusiness.a uses boost::gregorian, that is, libboost_date_time-mgw34-d-1_34_1.a, so libboost_date_time-mgw34-d-1_34_1.a should be listed after libfxoverlayBusiness.a, but you have listed it before. So: try to change the order of the "*.o" and "*.a" to make the linker happy. ;) HTH, Raul.
That was the exact problem. I could have spent days to find out this (I am new to C++ and such tricky things weren't in my book) Thank you for your efficient help !
