Want App, but Qt is creating a DLL instead

harveyab

I am using Qt Creator 2.8.84 (3.0.0-rc1) for IDE only on Windows XP.
The compiler is MinGW gcc (or g++) which was part of a ~~Pelles C~~ CodeBlocks installation.
With this code, I get a bad .exe file.
It looks like it is creating a dll, but I want an App.
I know I should be linking with some libraries, but I don't know which ones or how to specify them.
Should I be using CMake instead?

# IFW32.pro

CONFIG -= qt
CONFIG -= app_bundle

# To stop this error: undefined reference to 'WinMain@16'
win32:QMAKE_LFLAGS += -shared

SOURCES += main.c

C Source file:

// main.c

#include <windows.h>

int WINAPI wWinMain(HINSTANCE i, HINSTANCE pi, PWSTR szCmdLine, int cs)
{
  MessageBoxW(NULL, szCmdLine, L"Win32 Test", MB_OK);

  return 0;
}

Output:

Starting C:\Documents and Settings\Owner\A_IFW32\debug\IFW32.exe...
Failed to start program. Path or permissions wrong?
C:\Documents and Settings\Owner\A_IFW32\debug\IFW32.exe exited with code -1

When I look in the .exe file with exeinfo.exe, I see:

Characteristics            : 
 * The file is a dynamic-link library

win32:QMAKE_LFLAGS += -shared

This is your problem.

You need to call your main function WinMain, not wWinMain

@aha_1980 Thank you. That fixed both problems, but printed garbage until I changed to MessageBoxA() and fixed the pointer sizes and types. Here is the final two files:

IFW32.pro

CONFIG -= qt
CONFIG -= app_bundle
SOURCES += main.c

main.c

#include <windows.h>
int WINAPI WinMain(HINSTANCE i, HINSTANCE pi, LPSTR szCmdLine, int cs)
{
  MessageBoxA(NULL, szCmdLine, "Win32 Prog", MB_OK);
  return 0;
}

@harveyab said in Want App, but Qt is creating a DLL instead:

CONFIG -= app_bundle

You can also remove this line. It is only relevant on macOS, while you are targetting Windows only.
