The move constructor is implicitly deleted because the copy-constructor is explicitly deleted?
How can I easy fix it?

Hello Matteo,
There is a problem here:
QTFStr Tensoflessione::Instabilitaqtf(QTFStr &qtf)
{ // ----------
// ^
// You are passing a reference (which can be modified, as you do below.
String risultato;
risultato << "(σ[, t,0,d]/ f[, t,0,d]) + (σ[, m,y,d]/ k[, crit] * f[, m,y,d]) + K[, m]*(σ[, m,z,d]/ f[, m,z,d]) <= 1 &";
risultato << "(σ[, t,0,d]/ f[, t,0,d]) + K[, m]*(σ[, m,y,d]/ f[, m,y,d]) + (σ[, m,z,d]/ k[, crit] * f[, m,z,d]) <= 1 ";
risultato << GetVerificaInst();
qtf.StartTable(3,2,2,10).CharSize(12);
qtf.TableSubTitle("Instabilità flesso-torsionale");
qtf.LeftCellMargin(75)("l[, eff]").LeftCellMargin(15).AlignRight()
(Format("%.2f", GetInstab().leff)).AlignLeft()("mm")("Lunghezza libera di inflessione");
qtf.LeftCellMargin(75)("σ[, crit]").LeftCellMargin(15).AlignRight()
(Format("%.2f", GetInstab().sigmam_critico)).AlignLeft()("")("Tensione critica di svergolamento");
qtf.LeftCellMargin(75)("λ[, rel]").LeftCellMargin(15).AlignRight()
(Format("%.2f", GetInstab().lambda_relm)).AlignLeft()("")("Snellezza relativa di svergolamento");
qtf.LeftCellMargin(75)("k[, crit]").LeftCellMargin(15).AlignRight()
(Format("%.2f", GetInstab().kcrit)).AlignLeft()("N/mm[` 2]")("Coefficiente di sbandamento laterale");
qtf.TableSubTitle(risultato);
qtf.EndTable();
qtf.TableSubTitle(risultato);
qtf.EndTable();
return qtf;
//----------
// ^
// Then, compiler attempts (by default) to copy qtf (But you need to explicitly define a copy constructor, which is missing, and in it, explicity copy the members of your class (using clone() ), They are causing the error.)
// By the way, returning a QTFStr from this function shoudn't be necessasy at all, since you are already modifying the referenced instance! (it is non-const), unless you really need a copy of it. It is a much cheaper solution.
}
OR, if you don't use the referenced variable qtf after calling the method but you need your method to return a QTFStr, you can move it instead.
[
QTFStr(QTFStr&&) = default;
QTFStr& operator=(QTFStr&&) = default;
Then,
And please read about copy and move semantics of both C++11 (StackOverFlow has plenty of good articles on it), and UPP.
Best regards,

Thank you Oblivion,
I read something about copy and move semantics and I solved my issue defining a copy constructor as you suggested.
By the way is not clear for me when you write:

What is the much cheaper solution?
And then, how can I define a copy constructor for a Template<class T> function such as:
template<class T> void SortDurata(VectorMap<int, T> &Load)
{
//Riordina VectorMap in ordine crescente
Vector<int> keys = Load.PickKeys();
Vector<T> values = Load.GetValues();
IndexSort(keys, values);
Load.Clear();
Load = VectorMap<int, T>(keys, values);
}

Hello,
How do you want to define copy constructor for the function? It is impossible, you can only define copy constructor for template type T and try to recompile your program. You should also provide information what is T in template generation.
We need more information which line is that:
TabellaCarichi.cpp (192):

Hello,
I believe you should clone or pick while assigning to SLU & SLE variables:
SLU = pick(combiner.GetSluVector()); <<<< ROW 192
// Sle
combiner.CombineSLE();
SLE = clone(combiner.GetSleVector();) <<<< ROW 195
The bad thing here is the code design:
VectorMap<String, Vector<Value> > &GetSluVector() { return SLU; } <<<< pick(SLU) ???
VectorMap<String, Vector<Value> > &GetSleVector() { return SLE; } <<<< pick(SLE) ???
// Add const VectorMap<String, Vector<Value>>& GetSluVector { return SLU; }
// Now somebody can call GetSluVector().Clear() that destroys your class encapsulation. The pick operation would be disallow.
// In c++11 you do not need to make space after > in template, so ">>" is valid.
// Please also consider writing your code in plain English. It can be hard for the first time, but it will percent in the future.
Sincerely,
Klugier

Thank you Klugier!
I applied the following changes too:
template<class T> void SortDurata(VectorMap<int, T> &Load)
{
//Riordina VectorMap in ordine crescente - durata di carico
Vector<int> keys = Load.PickKeys();
Vector<T> values = Load.PickValues(); <<< OLD "Load.GetValues()"
IndexSort(keys, values);
Load.Clear();
Load = VectorMap<int, T>(pick(keys), pick(values)); <<< OLD "VectorMap<int, T>(keys, values)"
<<< why i need pick() here ?????????
}
I'm agree with you and I'm so sorry for the code not always in English. I wrote it year ago and now I have thousand rows to update.
Sure I'll take it in consideration for the next project!
Thanks,
Matteo
