Sorry I don't have time at the moment to give a more complete description of the problem (and hopefully a fix, as well), but big_integer does not yet compile under CW 9.2 on Mac OSX (10.2.8). The error list is huge, but the important one seems to be : Unimplemented C++ feature big_integer.hpp line 153 The portion in question is template<class T> friend bool operator<(T lhs, const expression<Base>& rhs) { return rhs > lhs; } which doesn't strike me as all that odd, but maybe I'm missing something. I'll try to look at it more, later and see if I can fix the problem. Also, I would love to see a big_float to go along with big_integer. I haven't thought about it enough to know if they should be separate libraries or different facets of the same. John Phillips Richard Peters wrote:
I have uploaded a new version of the big_integer library which also compiles with GCC 3.4.0 (cvs version). This version now compiles on compilers which implement two-stage name lookup. The library is available at http://groups.yahoo.com/group/boost/files/big_integer/, the version is 0.1.

A few months ago there was some discussion about an arbitrary magnitude integer library. I have now implemented such a library, which is located at http://groups.yahoo.com/group/boost/files/big_integer/.
Compiling the code generate hundreds of failures because of two-stage name lookup. You tested it under MSVC 71 and GCC 3.2 which both fail to
implement
lookup rules correctly. I suggest you try again with GCC 3.4.0 (a
pre-release
binary package should be available now) or EDG-based compilers. -- Giovanni Bajo
