vector<> error

[paolopiace]

The following simple volcalc.cpp code compiles with no errors (and works) in Windows Visual C++.
It simply sizes the "alldata" array later in the code.

With g++ v.4.3.2 for Linux instead I get the error reported hereby.

I would thankfully appreciate any help (including tough critics to the code).

volcalc.cpp:26: error: template argument for ‘template<class _Alloc> class std::allocator’ uses local type ‘main(int, char**)::series’
volcalc.cpp:26: error: trying to instantiate ‘template<class _Alloc> class std::allocator’
volcalc.cpp:26: error: template argument 2 is invalid
volcalc.cpp:66: error: request for member ‘resize’ in ‘alldata’, which is of non-class type ‘int’

int main(int argc, char *argv[])
{
       struct series {
               ....
       };
       int nr;
....
       vector<series> alldata;   // line 26

....    // calculate nr as int.

       alldata.resize(nr);  // line 66
}

I just compiled your code on linux. I this for some reason it does not like the fact that struct is declared local. If you declare struct as global it will be working.

Thanks! But I cannot change the code so drastically. Little things, yes, but this change is big.

The code is wrong and violates standards: http://stackoverflow.com/questions/742607/using-local-classes-with-stl-algorithms

Wow! Thanks so much. You need ages of experience to know subtleties like that.

Hence, MS Visual C++ is either forgiving or... one step ahead.
