[Insight-developers] compilation error with system vxl

[Arnaud GELAS]

Hi guys,

I have just tried to build itk, with an installed version of vxl and I 
get the following error:

[ 93%] Building CXX object 
Code/Numerics/FEM/CMakeFiles/ITKFEM.dir/itkFEMLinearSystemWrapperVNL.o

unsigned int, unsigned int)’:

In the recent version of vnl mult is now protected, whereas in the itk 
version mult is public...

If I am not wrong using directly operator * would work for both 
versions. Any objection?

Cheers,
Arnaud
