[Boost-users] Additional information on linking problems

Hi,

I have done some additional testing on th eproblem that I reported 
yesterday, and I have found that the problem I was having with static 
linking under gcc 2.95.3 also occurs on gcc 3.2.2.

I get basically the same error message (see below).

I guess that the reason I get the message for the static linking but not 
for the dynamic linking might be that the undefined references in a 
shared library are ok as long as those functions are not called.  Is 
that correct?  I looked at the code, and as far as I can tell, the 
functions that the compiler is complaining about are in fact defined.

Does anyone have any suggestions?

Thanks,
Daniel
