[Insight-users] Compiling problem of vnl_sse.h with GNU c++ compiling

[Luis Ibanez]

Hi John,

Have you enabled the CMake flag:

             VNL_CONFIG_ENABLE_SSE2   ?

If so, please turn it OFF, (back to its default value).

The SSE code in VXL has not been extensively tested.

You can double check the value of this variable by
rerunning ccmake and using the "t" key to see the
Advance variables. Then use "/" to search for "SSE".


Please let us know if you still see any problems
after turning this flag OFF.


   Thanks


      Luis
