[OpenWalnut-Dev] Question concerning some template code

[Alexander Wiebel]

Hi guys.

I have a problem with some of OpenWalnut's template code and 
VisualStudio's compiler. The following diff shows what I need to do to 
get it compile.

diff -r 2667e3ca1210 src/common/math/WTensor.h

If I do not do this I get error messages like the following for WTensorSym.h

Any Ideas?
