so shared library problem

Guys, quite newbie stuff:
I have a .so shared library with my brand new InfoBox widget placed in a MTR namespace.
Then I have a test program:

Code:

---

#include <QApplication>
#include <QtCore>
#include <QtGui>
 
int main(int argc, char* argv[]) {
	QApplication app(argc, argv);
	MTR::InfoBox ib;
	ib.show();
	app.exec();
	return 0;
}

---

its .pro:

Code:

---

TEMPLATE = app
CONFIG += qt
LIBS += -L/home/mtr/Programowanie/Projekty/MTRInfoBox -lMTRInfoBox
SOURCES += main.cpp

---

as you see I link the directory of my .so file as well as its name without "lib" prefix and .so* suffix.

I do not receive any messages that libMTRInfoBox.so.1.0.1 file hasn't been found.

Anyway I receive a message as if my test program did not know MTR::InfoBox class. Furthermore it doesn't recognize MTR namespace.

All in all I must have made some mistake somewhere...

The application must include a header which declares MTR::InfoBox (just like you include Qt headers which declare Qt classes).

I have added

Code:

---

#include <MTRInfoBox>

---

and I received:

Code:

---

main.cpp:4:22: error: MTRInfoBox: No such file or directory

---

then I tried:

Code:

---

#include <MTR::InfoBox>

---

and I received

Code:

---

main.cpp:4:24: error: MTR::InfoBox: No such file or directory

---

The libMTRInfoBox.so.1.0.1 file is placed in /home/mtr/Programowanie/Projekty/MTRInfoBox folder.

You should have a header file together with libMTRInfoBox.so.1.0.1.

First, you must add

Quote:

---

INCLUDEPATH += /home/mtr/Programowanie/Projekty/MTRInfoBox

---

to the .pro file to make it possible to include a header file from /home/mtr/Programowanie/Projekty/MTRInfoBox.

Then, you should use the exact name of the header file in include directive, not "MTR::InfoBox". I don't know what is the header called but let's say its name is mtrinfobox.h:

Code:

---

#include "mtrinfobox.h"
