Problem itegrating Ncreport to my application

advseo32

Hi every body

i got a probleme when i want to itegrate ncreport to my projects

her is what i use in .pro file

@QT = xml sql gui core
TEMPLATE = app
CONFIG += warn_on
qt
thread
release
TARGET = MyApplication
INCLUDEPATH = ncreport/includes
HEADERS += ...
SOURCES += ...
win32 {
LIBS += lib/NCReport2.lib
}@

Note: my apllication directory is : E:\apprendreQt\gestionstock6

ncreport includes directory is : E:\apprendreQt\gestionstock6\ncreport\includes

ncreport lib directory is : E:\apprendreQt\gestionstock6\ncreport\lib

i get the error
@
:-1: erreur : cannot find -l/ncreport2.lib@

advseo32

Now i got this error

E:\apprendreQt\gestionstock6\vente.cpp:221: erreur : undefined reference to `_imp___ZN8NCReportC1EP7QObject'

SGaist

Hi,

You should rather have something like this:

@
LIBS += -Llib -lNCReport2
@
it's a lower case before NCReport2

advseo32

i always get the same error

her is my .pro file after update

SGaist

No backslash in paths
And the -L switch is to add a path to the list of searchable location to get libriaries to link.

@
LIBS += -L"E:/apprendreQt/gestionstock6/includes/lib" -lNCReport2
@

i'm using using Qtcreator with minGW 4.8 compilator

my libs : NCReport2.lib
NCReportDebug2.lib

i tried this but still getting an other error

@INCLUDEPATH += "E:/apprendreQt/gestionstock6/includes/include"
LIBS += -L"E:/apprendreQt/gestionstock6/includes/lib"-lNCReport2@

this is the message in french "Le programme s'est terminé subitement."

i think is " The program ended suddenly." in english

SGaist

If you want to have the proper lib linked you can use a construct like this

@
NCREPORT = NCReport2
CONFIG(debug, debug|release): NCREPORT = NCReport2Debug
LIBS += -l$$NCREPORT
@

So your can start your application now and you are probably missing some dependencies. Do you have the path to your NCReport2 dll in your PATH ?

advseo32

no, should i include NCReport.dll ??

and how i can do this ?

SGaist

Either edit the PATH variable in the Run panel and add the path where NCReport.dll is contained or copy the dll in your executable folder.

advseo32

after placing NCReport2.dll with my .exe file , i got the same error

“Le programme s’est terminé subitement.”

i think is “ The program ended suddenly.” in english

this is .pro file

Then start your program in debug mode with a debugger.

This error message just says that the application died not why.

advseo32

Unfotaintly, i start it in debug mode , and i got this error
@during startup program exited with code 0xc0000139@

SGaist

Then check that all dlls you might be using can be found at runtime

advseo32

i'm using only

QT += core gui sql xml

and they are present in the C:\Qt\Qt5.1.0\5.1.0\mingw48_32\bin

and for NCReport lib i have placed with the .exe file in the same directory

really i have no idea about this porblem

advseo32

Now i getting this error

@E:\apprendreQt\gestionstock6\vente.cpp:25: erreur : undefined reference to `_imp___ZN8NCReportC1EP7QObject'

E:\apprendreQt\build-gestionstock6-Desktop_Qt_5_1_0_MinGW_32bit-Debug\debug\vente.o:-1: In function `ZN5Vente23on_pushButton_4_clickedEv':

E:\apprendreQt\gestionstock6\vente.cpp:224: erreur : undefined reference to `_imp___ZN8NCReport20runReportToQtPreviewEv'@

this is my implementation of NCreport

@void Vente::on_pushButton_4_clicked()
{
m_report->reset(true);
m_report->setReportFile("E:/apprendreQt/build-gestionstock6-Desktop_Qt_5_1_0_MinGW_32bit-Debug/reports/abdeu.xml");
m_report->runReportToQtPreview();

}@

SGaist

is NCReport also built with mingw ?

advseo32

i don't konw ,because i have no exprience with Mingw ,

but i have download the last version from official site for Qt 5.1.0

and his extension is .lib

SGaist

Then there's your problem, you are trying to link a library built with VisualStudio while using mingw. The name of the installers from the download section of NCReport is pretty clear.

advseo32

yeah i have downloaded all versions

@application/octet-stream NCReport2.10.0_Windows_x86_VS2010_Qt5.1.0_Evaluation.exe (18.0 MB)

application/octet-stream NCReport2.10.0_Windows_x86_VS2010_Qt4.8.5_Evaluation.exe (10.6 MB)

application/octet-stream NCReport2.10.0_Windows_x86_MinGW_Qt4.8.5_Evaluation.exe (14.1 MB)@

i have used the last one but not working for me also

i'm using Qt 5.1.0

plz help me i'm completely lost

SGaist

You can't use a library built with Qt 4 if you are using Qt 5 and also AFAIK, you can't link a c++ library from visual studio using mingw. So you have two options:

Change your Qt version and compiler for Visual Studio

Ask the NCReport developer to release a Qt 5 mingw version
