mysqlpp::sql_set and mysql_sql_set_null compiler errors

[Adrian Cornish]

Hi All,

I cannot compile even a simple example using sets? Can someone point
me at the obvious errors I must doing.

Using SVN At revision 2676.
gcc version 4.5.0 (GCC)

Looking at preprocessor output the begining of the struct defintion looks good
struct Foo
{
   mysqlpp::sql_int anumber;
   mysqlpp::sql_set set1;
   mysqlpp::sql_set_null set2;
   mysqlpp::sql_int another;
   Foo() : table_override_(0) { }
   Foo(const mysqlpp::Row& row);
   void set(const mysqlpp::Row &row);
   Foo(const mysqlpp::sql_int &p1) : anumber (p1), table_override_(0) {}

Looking at the function in question I can't see anything obviously wrong
void populate_Foo(Foo *s, const mysqlpp::Row &row)
{
   mysqlpp::NoExceptions ignore_schema_mismatches(row);
   s->anumber = row["anumber"].conv(mysqlpp::sql_int());
   s->set1 = row["set1"].conv(mysqlpp::sql_set());
   s->set2 = row["set2"].conv(mysqlpp::sql_set_null());
   s->another = row["another"].conv(mysqlpp::sql_int());
}

I dont understand why its trying to apply conversion.
