Trying to export to Excel

I have found some code that I am playing with to learn how to export data to Excel

Code:

---

QAxObject* excel = new QAxObject("Excel.Application", 0);
QAxObject* app = excel->querySubObject("Application()");
QAxObject* wbks = excel->querySubObject("Workbooks()");
QAxObject* wb = wbks->querySubObject("Add()");
QAxObject* ws = wb->querySubObject("Worksheets(int)", 1 );
 
//Show Excel
app->setProperty("Visible", true );

---

However, I get the following errors:

---

release/mainwindow.o:mainwindow.cpp::: error: undefined reference to `QAxObject::QAxObject(QString const&, QObject*)'
release/mainwindow.o:mainwindow.cpp::: error: undefined reference to `QAxBase::querySubObject(char const*, QVariant const&, QVariant const&, QVariant const&, QVariant const&, QVariant const&, QVariant const&, QVariant const&, QVariant const&)'

I have #include <QAxObject> at the beginning of the code.
Can someone tell me where I am going wrong?
Thanks.

Hi, you are missing the necessary libraries during linking (QAxServer.lib and/or QAxContainer.lib). Add them to the linker command line and it should work.

read about ActiveQt module in Assistant. Do you have your ActiveQt module already compiled?

I've got no idea about the ActiveQt module being compiled or not!!!?
I installed the latest SDK, and then installed the latest Qt Creator, both .exe's. I didn't specifically compile anything.
How do I check, and if needed, go about compiling this?

I have added the following to my .pro file, but stil same error...

Code:

---

LIBS += -QAxServer.lib \
        -QAxContainer.lib

---

Thank you. I corrected it. It is now

Code:

---

LIBS += -lqaxserver \
        -lqaxcontainer

---

and it works!

Actually just needed

Code:

---

1.LIBS += -lqaxserver

---

My apologies, it is actually the other library , i.e. qaxcontainer, not qaxserver that is needed.
Not sure why it actually compiled using the qaxserver only, but this morning it doesn't anymore, and swopping them now lets it work again.

i added this and its work.
CONFIG += qaxcontainer
