I fixed the Eigen2 problem with a cast. Hopefully it still works for Eigen3.
I'm getting quite a few trivial compile warnings though, Geoff, with MSVC - maybe you can look into these: 1>..\..\..\src\distgeom.cpp(126) : warning C4244: 'initializing' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(131) : warning C4244: '=' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(138) : warning C4244: '=' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(158) : warning C4244: 'argument' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(159) : warning C4244: 'argument' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(163) : warning C4244: 'argument' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(164) : warning C4244: 'argument' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(237) : warning C4244: '=' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(238) : warning C4244: 'argument' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(239) : warning C4244: 'argument' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(243) : warning C4305: 'initializing' : truncation from 'double' to 'float' 1>..\..\..\src\distgeom.cpp(251) : warning C4244: '=' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(252) : warning C4305: '*=' : truncation from 'double' to 'float' 1>..\..\..\src\distgeom.cpp(255) : warning C4305: '=' : truncation from 'double' to 'float' 1>..\..\..\src\distgeom.cpp(257) : warning C4305: '=' : truncation from 'double' to 'float' 1>..\..\..\src\distgeom.cpp(262) : warning C4305: '=' : truncation from 'double' to 'float' 1>..\..\..\src\distgeom.cpp(265) : warning C4305: '=' : truncation from 'double' to 'float' 1>..\..\..\src\distgeom.cpp(269) : warning C4305: '=' : truncation from 'double' to 'float' 1>..\..\..\src\distgeom.cpp(276) : warning C4244: '=' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(277) : warning C4244: '=' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(279) : warning C4244: '=' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(280) : warning C4244: 'argument' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(281) : warning C4244: 'argument' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(305) : warning C4244: '=' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(306) : warning C4244: '=' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(307) : warning C4244: '=' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(310) : warning C4244: '=' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(311) : warning C4244: '=' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(312) : warning C4244: '=' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(313) : warning C4244: '=' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(316) : warning C4244: 'argument' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(317) : warning C4244: 'argument' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(294) : warning C4101: 'i' : unreferenced local variable 1>..\..\..\src\distgeom.cpp(294) : warning C4101: 'j' : unreferenced local variable 1>..\..\..\src\distgeom.cpp(395) : warning C4244: 'argument' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(396) : warning C4244: 'argument' : conversion from 'double' to 'float', possible loss of data 1>..\..\..\src\distgeom.cpp(362) : warning C4101: 'l_bc' : unreferenced local variable - Noel On 26 July 2012 19:39, Jeff Janes <jeff.ja...@gmail.com> wrote: > On Thu, Jul 26, 2012 at 10:35 AM, Geoff Hutchison > <ge...@geoffhutchison.net> wrote: >>> When I build the most recent revision in SVN, 4965, with Eigen2 >>> installed, it fails to compile due to an ambiguous overloaded call to >>> Matrix.
