[Solved]Qt4.8.1 for Desktop (MinGW) Compiler Error (-Wl,-subsystem,windows)
-
Good day
I have the following program:
@/* temp.cpp Qt test file */
#include <iostream>int main()
{
using namespace std;
cout << "Hello world";
return 0;
}@I open Qt4.8.1 for Desktop (MinGW) and ran the following(also showing the output):
@
d:\temp>qmake -projectd:\temp>qmake
d:\temp>mingw32-make
mingw32-make -f Makefile.Debug

So I compiled the same project with qmake Makefile and directly with mingw. As you can see the qmake compilation compiled a file doing nothing where the mingw compiled correctly. Any ideas why or what is going on? The SDK is working correctly so the installed Qt is not broken.Any help please?

-Wl,-subsystem,windows makes an application with GUI and -Wl,-subsystem,console makes a console application - and those were added because you created an Qt GUI application instead a Qt console application //add CONFIG += console to your .pro file (when you create a console application) and then run qmake and it should build just fine.
