Hi, 

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

g++ -LC:\dev\workspace\fxoverlayFundation\Debug 
-LC:\dev\workspace\fxoverlayBusiness\Debug -LC:\dev\boost_1_34_1\stage\lib 
-ofxoverlayBusinessTests.exe emptyTests.o allTests.o InterestRateTests.o 
InterestCurveTests.o -lboost_date_time-mgw34-d-1_34_1 
-lboost_unit_test_framework-mgw34-d-1_34_1 -lfxoverlayBusiness 
-lfxoverlayFundation 
C:\dev\workspace\fxoverlayBusiness\Debug/libfxoverlayBusiness.a(InterestCurve.o): 
In function 
`ZSt10_ConstructISt4pairIKSsN3com9fxoverlay8business12InterestRateEES6_EvPT_RKT0_':

std::basic_ostream<char, std::char_traits<char> >&)]+0x57): undefined 
reference to `boost::gregorian::greg_month::as_long_string() const' 

Both "libboost_date_time-mgw34-d-1_34_1.a" and 
"liboost_unit_test_framework-mgw34-d-1_34_1.a" are in 
"C:\dev\boost_1_34_1\stage\lib" 

Here are my includes : 
#include <boost/date_time/posix_time/ptime.hpp> 
#include <boost/date_time/posix_time/time_parsers.hpp> 
#include <boost/date_time/posix_time/time_formatters.hpp> 
using namespace boost::posix_time; 

The functions I actualy use are : from_iso_string() and to_simple_string() 
(wich build a ptime from a string and return a string from a ptime) 

I would apreciate any suggestion to make my program compile and link. 

Regards, 
Jérôme
