Calling the functions of Qt from the C++ files

[jigar23]

I have my own C++ file random.cc that includes files

@#include <QMainWindow>
#include <QApplication>@

I build my C++ file as

@g++ random.cc mainwindow.cpp -I ../qt/5.3/gcc_64/include/QtWidgets/ -I ../qt/5.3/gcc_64/include -fPIC@

However, it throws the following error:

@mainwindow.cpp:2:27: fatal error: ui_mainwindow.h: No such file or directory
#include "ui_mainwindow.h"@

Is there a way to prebuild the file ui_mainwindow.h.?

This is path issue. Compilation is not able to find the ui_main* files. You can use uic tool generate the ui_main*.h files and keep it where you require. Or you can use UI_DIR directive in pro file to keep you ui_main*.h into specific directory.

Can you show your *.pro file
and what IDE you are using?
