Hi, I am a newbie to all this programmer stuff. I am a physics student doing some computer simulations. I was trying to use the special function atanh from boost libraries but couldn't.

The error message reads d:\boost_1_28_0\atanh.hpp(77) : error C2989: 'atanh_helper1_t' : template class has already been defined as a non-template class

Some advised me to update my VisC++ ver 6.0 compiler.

How can I do that?

Does anybody out there have any better advise?

Unfortunately, there really isn't any better advice at this time. The special functions library (including atanh) requires a compiler that supports class template partial specialization. Unfortunately, no publicly available version of the Microsoft C++ compiler supports partial specialization, so this won't work with your compiler, and upgrading won't even help. (Unless "upgrading" to you involves switching to another compiler vendor) Doug

Somewhere in the E.U., le 20/08/2002 Bonjour I made some changes which would presumably make your compiler happy without compromising the quality for its betters. I'll try to have them tested (at least in version 7 of that compiler) so they can appear in the upcomming release. A bientot Hubert Holin Hubert.Holin@Bigfoot.com sen_al2002 wrote:
