Hello Daniel,

> Yes, the pre-compiled libraries are there.
I built the gmp binaries that are distributed in the Windows installer using a 
modified version of Brian Gladman's GMP/MPFR for Windows:

http://fp.gladman.plus.com/computing/gmp4win.htm

(these days Mr Gladman supports Visual Studio 2008, but at the time I built 
these it was Visual Studio 2005).


I've seen this error reported in the past, but I was never able to figure out 
what is causing it because I can locally compile CGAL  programs with these debug 
gmp binaries with no problems.

I suspect the problem is the existence of slighly differnent CRT versions for 
VS2005.

I've modified Gladman's project file to accomodate the autolink name mangling 
used in the binaries distributed with CGAL. I suppose that as a last resort you 
could do the same.

A probably much simpler path for you would be to build gmp using Gladman's 
project files as is and then disable autolinking for gmp and mpfr via the 
compile time switches:

CGAL_NO_AUTOLINK_GMP
CGAL_NO_AUTOLINK_MPFR

in which case you'll have to setup your project file to link against gmp.lib 
explicitely.

Or, keep autolinking but disable name mangling via the compiler flag:

CGAL_AUTO_LINK_NOMANGLE

This will autolink to "gmp.lib" and "mpfr.lib", but you'll have to setup the 
link directory where these libraries are, which won't be the same for Release 
and Debug (as it is now since the name mangling discriminates that)
