HELP:[pq++]:constructor `PgDatabase::PgDatabase()' is protected

Hello,

I'm getting the following problem:

In file included from CDatenbankSQL.cpp:8:
CDatenbankSQL.h:20: warning: ANSI C++ forbids
initialization of member `data'
/usr/local/pgsql/include/libpq++.H: In method
`CDatenbankSQL::CDatenbankSQL()':
/usr/local/pgsql/include/libpq++.H:74: constructor
`PgDatabase::PgDatabase()' is protected
CDatenbankSQL.cpp:11: within this context
CDatenbankSQL.cpp:11: in base initialization for class
`PgDatabase'

The class instantiates a public member 'PgDatabase
data("soft4")'.
The constructor looks like this:
CDatenbankSQL::CDatenbankSQL(void)
{
iError = 0;
sprintf(dbName, "soft4");
iRowPos = 0;
iFieldPos = 0;
iConnected = 0;
}

what's wrong there ?

thanks in advance.

cheers,
Aga
