Sigh.  I thought so.  I am having a dickens of a time getting libpcl to
compile with the --std=c++11 flag. It seems that libvtk, used heavily by
PCL, doesn't like C++11. (We can't compile our library without the flag
since we actually use many C++11 features).  I will continue to work on
this.

Thanks, this discussion has at least pointed me in the direction I need to
go.


​I have no problem compiling PCL 1.8.0 and VTK 7.0.0 with C++11 support . 
In the past VTK 6 (not sure on the exact version) and PCL 1.7.2 also 
worked fine.

The VTK wiki seems to indicate VTK 6.1 is compatible with C++11 [1].

Maybe it is an issue with the compiler you're using. Some GCC versions had 
incomplete C++11 support iirc.

--------------------
Quite right, as soon as I got VTK 7.0, the PCL library compiled fine (we 
only had 5.8 and 6.0 until earlier today). Now my problem is purely with 
our own library. 

VTK 6.0 still had the issue in vtkMath.h where it used 'using namespace 
std' and then tried to call isinf or isnan.  VTK7.0 correctly omits the 
using directive and calls std::isinf and std::isnan.  It is possible this 
was actually fixed in 6.2 or 6.3.
