[Interest] status_assert() error when compile plugin

[Oswaldo F. Filho]

Hi,

I try to compile a SQL plugin using
*qt-everywhere-opensource-src-5.1.1 *version.
This plugin already compiled and worked with *Qt-4.8.1.*

I had this .pro file in
*"./qt-everywhere-opensource-src-5.1.1/qtbase/src/plugins/qldrivers/sqlcipher*"
directory:

TARGET   = qsqlcipher

HEADERS  = ../../../sql/drivers/sqlite/qsql_sqlite.h
SOURCES  = smain.cpp \
           ../../../sql/drivers/sqlite/qsql_sqlite.cpp

!system-sqlite:!contains( LIBS, .*sqlite.* ) {
    CONFIG(release, debug|release):DEFINES *= NDEBUG
    DEFINES     += SQLITE_OMIT_LOAD_EXTENSION SQLITE_OMIT_COMPLETE
SQLITE_HAS_CODEC
    INCLUDEPATH += include
    LIBS        += -Llib -lsqlite3 -lcrypto
    QMAKE_RPATHDIR += lib
} else {
    LIBS *= $$QT_LFLAGS_SQLITE
    QMAKE_CXXFLAGS *= $$QT_CFLAGS_SQLITE
}

include(../qsqldriverbase.pri)


And I had this main.cpp:

#include <QtSql/QSqlDatabase>
#include <qstringlist.h>
#include "../../../sql/kernel/qsqldriverplugin.h"
#include "../../../sql/drivers/sqlite/qsql_sqlite.h"

QT_BEGIN_NAMESPACE

class QSQLCipherDriverPlugin : public QSqlDriverPlugin
{
public:
    QSQLCipherDriverPlugin();

    QSqlDriver* create(const QString &);
    QStringList keys() const;
};

QSQLCipherDriverPlugin::QSQLCipherDriverPlugin()
    : QSqlDriverPlugin()
{
}

QSqlDriver* QSQLCipherDriverPlugin::create(const QString &name)
{
    if (name == QLatin1String("QSQLCIPHER")) {
        QSQLiteDriver* driver = new QSQLiteDriver();
        return driver;
    }
    return 0;
}

QStringList QSQLCipherDriverPlugin::keys() const
{
    QStringList l;
    l  << QLatin1String("QSQLCIPHER");
    return l;
}

Q_EXPORT_STATIC_PLUGIN(QSQLCipherDriverPlugin)
Q_EXPORT_PLUGIN2(qsqlite, QSQLCipherDriverPlugin)

QT_END_NAMESPACE


I tried to compile this and result was:

I changed header file from "../../../sql/drivers/sqlite/qsql_sqlite.h" to
"../../../sql/drivers/sqlite/qsql_sqlite_p.h"

I tried to compile again and It has a new error:

Please, what is happened?

The problem occurs in Q_EXPORT_PLUGIN2, but where and why?

Thanks.
