[vtk-developers] Errors when compiling VTK v6.0.0 in C++11 mode

[David Gobbi]

Hi Kevin,

Thanks for the report.  I believe that this can be fixed.  The patch
that Kyle provided will not work (we already tried that in earlier
rounds of testing) so now I am investigating in more depth. I've
discovered that our cmake check for VTK_HAS_STD_ISINF doesn't work
because cmake's check_symbol_exists() function uses the C compiler,
rather than the C++ compiler, for its try_compile and therefore
doesn't work with namespaced functions.  I hope to have a patch up on
gerrit soon.

 - David
