Hello,
I am trying to use Qt but I get linker errors. I installed the
mingw64/mingw-w64-x86_64-qt5-static package. Is that sufficient to build
a basic hello word application?
The hello word program is this one:
***
#include <QApplication>
#include <QPushButton>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QPushButton hello("Hello world!");
hello.show();
return app.exec();
}
***
I had to add "QT += widgets" to my QtHello.pro to successfully compile
with the generated Makefile, but I now have linker errors...

I am not sure I have installed all that I need.
