[Quickfix-developers] Upgrading to quickfix 1.12.4: C++/MySQLConnection.h:98: warning: suggest parentheses around assignment used, as truth value

[Abel M. <am...@bo...>]

Hi everyone,

we're upgrading our quickfix applications to last version, 1.12.4, and=20
we found some problems, so maybe someone could give us a hand.
Compiling the version, we've seen this warning:

C++/MySQLConnection.h:98: warning: suggest parentheses around assignment =

used,   as truth value

which is this line:
while ( row =3D mysql_fetch_row( m_result ) )

We put the parentheses in order to avoid the warning, but now, we=20
compile the application and it crashs with a core.

It happens when we are making the new to a ThreadadSocketAcceptor =
object.

  _store_factory =3D new FIX::MySQLStoreFactory( *_settings );
  _log_factory =3D new FIX::MySQLLogFactory( *_settings );
=20
  try {
    _acceptor =3D new FIX::ThreadedSocketAcceptor (*_application,=20
*_store_factory,
                         *_settings, *_log_factory);  =20
  }  =20

quickfix is compile with ./configure --with-mysql=3D/usr in order to =
have=20
mysql support. It seems that we're missing something, but we are stuck=20
with this problem, so we'd appreciate your comments.

Regards,
Abel Monroy Ferrero
