Hi,

Where is your NCReport2 stuff located ?

advseo32

my NCreport2 is located in

E:\apprendreQt\gestionstock6\includes\lib

this is the full path

E:\apprendreQt\gestionstock6\includes\lib\libNCReport2.a

Remove the quotes in your LIBS variable. At the moment you are specifying a single (broken) -L option.

advseo32

ok, removing quotes i get another error

What does your main.cpp look like ?

advseo32

her is the code of main.cpp @#include "mainwindow.h"
#include <QApplication>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();

return a.exec&#40;&#41;;

}

SGaist

What happens if you don't pass the parent to when creating a NCReport ?

advseo32

i'm no longer getting the ealier error ,

now i get this error

@Starting C:\test\build-testncreport-Desktop_Qt_5_1_1_MinGW_32bit-Debug\debug\testncreport.exe...
The program has unexpectedly finished.

You need to run your application with a debugger to see where the error is triggered

advseo32

i get this error
@
During startup program exited with code 0xc0000135.@

SGaist

This is a library not found error, do you have the NCReport dll somewhere in your PATH ?

If not, got to the Run panel and update the PATH environment variable adding the path to the folder where that dll can be found.

advseo32

i have placed them before but i get the same error

i have deleted the debug folder , then recompile and replace the dll files

no it's working for me , but NCreport windows not appears yet only the main windows

advseo32

is this code right ?

@void MainWindow::on_pushButton_clicked()
{
NCReport *report = new NCReport(this);
report->reset(true);
report->setReportFile("E:\apprendreQt\gestionstock6\includes\reports\test.xml");
report->runReportToPrinter();
}

No, you don't escape the backslashes in your path. You either have to to that or since your using Qt, use forward slashes.

advseo32

Ok, it works
