got problem when compiled QxOrm.

[olekhanchai]

Hello,
I'm new in Qt Programming and I'm not very well in english.
I'm interesting in your QxOrm very much. It's look like powerful program.
I was download Boost Library and QxOrm compiled and install it.
Everything compiled OK. and then I used your sample code to test it.
But I got the error and got red underline on
QX_REGISTER_HPP_MY_TEST_EXE(drug, qx::trait::no_base_class_defined, 1)
and
QX_REGISTER_CPP_MY_TEST_EXE(drug)
when I compiled it.
what should I solution this problem?
my project.pro is :

QT += core QxOrm

QT -= gui

TARGET = drugexample
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app


SOURCES += main.cpp \
drug.cpp

HEADERS += \
drug.h

it's generated by Qt console program.

Best Regard,
Ole

Hello Ole,

The "Quick example step by step" is incomplete. You need to add:

precompiled.h:


#ifndef _QX_TEST_PRECOMPILED_HEADER_H_
#define _QX_TEST_PRECOMPILED_HEADER_H_

#include <QxOrm.h>

#include "export.h"

#endif // _QX_TEST_PRECOMPILED_HEADER_H_


export.h


#ifndef _MY_TEST_EXE_EXPORT_H_
#define _MY_TEST_EXE_EXPORT_H_

#ifdef _BUILDING_MY_TEST_EXE
#define MY_TEST_EXE_DLL_EXPORT QX_DLL_EXPORT_HELPER
#else // _BUILDING_MY_TEST_EXE
#define MY_TEST_EXE_DLL_EXPORT QX_DLL_IMPORT_HELPER
#endif // _BUILDING_MY_TEST_EXE

#ifdef _BUILDING_MY_TEST_EXE
#define QX_REGISTER_HPP_MY_TEST_EXE QX_REGISTER_HPP_EXPORT_DLL
#define QX_REGISTER_CPP_MY_TEST_EXE QX_REGISTER_CPP_EXPORT_DLL
#else // _BUILDING_MY_TEST_EXE
#define QX_REGISTER_HPP_MY_TEST_EXE QX_REGISTER_HPP_IMPORT_DLL
#define QX_REGISTER_CPP_MY_TEST_EXE QX_REGISTER_CPP_IMPORT_DLL
#endif // _BUILDING_MY_TEST_EXE

#endif // _MY_TEST_EXE_EXPORT_H_


and a pro file like:


TEMPLATE = app
TARGET = test

CONFIG += precompile_header
PRECOMPILED_HEADER = precompiled.h

INCLUDEPATH += /usr/local/QxOrm/include
LIBS += -L/usr/local/QxOrm/lib -lQxOrm

# Input
HEADERS += drug.h
SOURCES += drug.cpp main.cpp

Hello ChrisW67,
Thanks for your reply. I was compiled everything in Microsoft Windows 7 and use CYGWIN to build library. Everything was compiled OK. But it's still not work then it's has another occur like this :

debug/drug.o: In function `extended_type_info_typeid':
c:/Qt/2010.05/qt/include/boost/serialization/extended_type_info_typeid.hpp:86: undefined reference to `boost::serialization::typeid_system::extended_typ e_info_typeid_0::extended_type_info_typeid_0(char const*)'
c:/Qt/2010.05/qt/include/boost/serialization/extended_type_info_typeid.hpp:88: undefined reference to `boost::serialization::typeid_system::extended_typ e_info_typeid_0::type_register(std::type_info const&)'
c:/Qt/2010.05/qt/include/boost/serialization/extended_type_info_typeid.hpp:89: undefined reference to `boost::serialization::extended_type_info::key_reg ister() const'
.
.
.
seem like it's not link to library, right?
I try to compiled boost with visual studio 2008 and then it have error occur because the "libboost_serialization-vc90-mt-gd-1_42" not found.
when I change the solution to compiled with CYGWIN everything is OK and it can be build QxOrm too.
I was change my file with your recommendation and then it still error occur that I shown you on the top. What should I do?
So sorry about my english skill and thanks a lot for your help.

Best Regards,
Ole.

Then you need to ensure that your linker can find the Boost libraries. You do that with appropriate LIBS options in your PRO file; probably a single "-L" option and one or more "-l" options. The exact details will depend on where you have things installed and which Boost libraries are required.

Hello ChrisW67,

I still not yet done on QxOrm. I'm sure about my library and include file are correct.
Because I can build and run example program with boost library.
Then I build QxOrm everything is done too. But I got the new problem like this :

debug/drug.o: In function `IxClass':
c:/Qt/2010.05/qt/include/QxRegister/IxClass.h:80: undefined reference to `vtable for qx::IxClass'
debug/drug.o:c:/Qt/2010.05/qt/include/QxTraits/get_sql_type.h:185: undefined reference to `qx::trait::detail::get_sql_type_by_class_name(cha r const*, char const*)'
debug/drug.o:c:/Qt/2010.05/qt/include/QxTraits/get_sql_type.h:196: undefined reference to `qx::trait::detail::get_sql_type_by_class_name(cha r const*, char const*)'
debug/drug.o: In function `QxClass':

c:/Qt/2010.05/qt/include/../../inl/QxCollection/QxCollection.inl:41: undefined reference to `qx::IxCollection::~IxCollection()'
.
.
.

I see underline error on QX_DLL_EXPORT seem like the same problem in the first time that I ask you.
What should I do next?

Regards,
Ole.

Thanks for answer me.
