Hi,
I am using gcc version 3.3.1 under cygwin.
the following code produces a syntax error during compilation,
witch has no obvious reason for me.
#include <vector>
enum ids
{
NONE,
INT,
TUPLE,
};
template<int id, int el_id = NONE> struct type;
template<>
struct type<NONE>
{
};
template<int id, typename T, int el_id = NONE>
struct base
{
typedef T data_type;
};
template<>
struct type<INT> : base<INT, int>
{
};
template<int el_id>
struct type<TUPLE, el_id> : base<TUPLE, std::vector< type<INT> >, el_id>
{
data_type::const_iterator cit; // syntax error before ';' token
};
int main(void)
{
return 0;
}
Both Intel C++ 7.1 and Microsoft VC .NET compile this code.
If I replace the line :
struct type<TUPLE, el_id> : base<TUPLE, std::vector< type<INT> >, el_id>
with:
struct type<TUPLE, el_id> : base<TUPLE, std::vector< type<INT> >, NONE>
gcc does compile without errors.
Best regards,
Dirk

Hi Dirk,
Try this...
template<int el_id>
struct type<TUPLE, el_id> : base<TUPLE, std::vector< type<INT> >, el_id>
{
typename data_type::const_iterator cit; // No more error :-)
};
HTH,
