Re: Vc Build Error

[GRABNER Friedrich]

Matthias,

I updated my binutils to:

2.26.51.20151113

However it is not my default binutils so I am linking it through ccmake...

That being said I still receive the error message:

make: *** [all] Error 2

Do I need to completely update binutils or should this suffice?

Thanks,
Friedrich
