Hi, I am using BOOST to do math and have not been able to get the "findroot_demo.cpp" example of root finding to work. There seem to be a reference to rint(), which is not implemented in the C++ library for windows.

If you are using Visual Studio you need to have the Boost library path you are using referenced correctly in Project>Properties>Configuration Properties>C/C++>General>Additional Include Directories and Project>Properties>Configuration Properties>Linker>General>Additional Library Directories have you done this yet?

In Additional Include Directories I have: D:\src\boost_1_36_0 In Additional Library Directories I have: D:\src\boost_1_36_0\stage\lib "stage" is the directory where I compiled the BOOST libraries. I link against: libboost_unit_test_framework-vc90-mt.lib libboost_math_c99-vc90-mt.lib Please advice. 2010/9/16 Jared James Thompson <thompsjj@purdue.edu>

Unfortunately this is either a Boost or an MSVC bug depending upon your point of view :-( Boost.Interval depends upon a number of std lib rounding functions to do it's work. One of them is "rint" which MSVC used to supply, but for some reason recent releases have simply dropped it, with no suitable replacement. If you google for msvc and rint you should find some replacements for that function. HTH, John.

I tried this quickly using naïve (but plausible) rint code double rint(double x) { return floor(x + 0.5); } from http://suncallmoonbright.blogspot.com/2008/12/mingw-to-msvc-case-of-rint.htm l but then I got the error below -and decided someone who knew more about it should look at it ;-) Paul --- Paul A.

I have made a bug report on this issue some time ago. It should now be corrected in SVN, but I have not checked it out yet and tested it.
From what I understand it will be included in BOOST 1.46.
Thanks a lot for your help. Best regards Lars 2010/9/26 Paul A. Bristow <pbristow@hetp.u-net.com>
