std::vector in the union

[Stephane Routelous]

Hi,

I'm using yacc to parse a file.

In my case, I would like to include some vectors from stl in the union.
But, I can't because, in a union, you cannot have members with copy
constructors.

So, I tried :

typedef union
{
int iVal;
double fVal;
std::vector<MyObject*> objectsVal;
} YYSTYPE;

it doesn't work.
( with VC++ : error C2621: union '__unnamed' : member 'objectsVal' has copy
constructor )


As woraround, I tried also :

struct MyStruct
{
std::vector<MyObject*> objectsVal;
};

typedef union
{
int iVal;
double fVal;
MyStruct sVal;
} YYSTYPE;

I doesn't work too.
( with VC++ : error C2621: union '__unnamed' : member 'sVal' has copy
constructor )

Do you have any idea how I can achieve that ?

Thanks a lot,

Stephane
