Error instantiating std.container.Array

2015-03-02 Thread Francesco Cattoglio via Digitalmars-d-learn 
I'm trying to instantiate a std.container.Array of a given class 
(named Material), by a simple

Array!Material _myStuff;
I get two compile errors stating the following:

C:\D\dmd2\windows\bin\..\..\src\phobos\std\container\array.d(85):
Error: template std.algorithm.initializeAll cannot deduce 
function from argument types !()(Material[]), candidates are:

  C:\D\dmd2\windows\bin\..\..\src\phobos\std\algorithm.d(1502):
std.algorithm.initializeAll(Range)(Range range)
if (isInputRange!Range
   hasLvalueElements!Range
   hasAssignableElements!Range)
  C:\D\dmd2\windows\bin\..\..\src\phobos\std\algorithm.d(1530):
std.algorithm.initializeAll(Range)(Range range)
if (is(Range == char[]) || is(Range == wchar[]))
C:\D\dmd2\windows\bin\..\..\src\phobos\std\container\array.d(825): 
Error: template std.algorithm.copy cannot deduce function from 
argument types !()(Range, Range), candidates are:

  C:\D\dmd2\windows\bin\..\..\src\phobos\std\algorithm.d(7808):
std.algorithm.copy(Range1, Range2)(Range1 source, Range2 
target)
if (isInputRange!Range1  isOutputRange!(Range2, 
ElementType!Range1))


Any idea about what might be happening? I can't give a quick 
minimal example of the code since it is quite complex (and I 
failed at using dustmite trying to minimize it)

I'm really clueless... :P


Something is wrong with your Material class, but you'll need to 
show us a reduced example.

Try to reduce your Material class for a small failing example. 
It's probably your constructors or opAssign or something like 
that. Anyway, it's a bug if template errors from the 
implementation bubble up, so please file a report.

I tried to dub dustmite, but it failed with a 
object.Exception@DustMite\dustmite.d(220): Initial test fails


The dustmite version is the one that was bundled with dmd 
2.066.1-rc2.


I'll update dmd in the mean time, but I have a feeling that this 
is not related.

After a really long time I finally found what was wrong.

Wow, I honestly could have NEVER foreseen this.
This is all it takes for a class being unusable in a 
std.container.Array

class MyClass
{
void init();
}

.init is a special property of every type:
