WinMain@16 Issue

[mhoover]

I am trying to build a server with no Qt classes using qmake (since it creates Makefiles so well) with MinGW mixed in there.

I am able to build GUIs fine, but this server fails with:

[...]libmingw32.a(main.o):main.c.text+0x104): undefined reference to 'WinMain@16'.

There are thousands of posts on the web about this error, and I think I've tried all the fixes:

1. Changed int main() to void main()
2. Since this is a server with no GUI, I added CONFIG += console (same error with or without console)
3. Added "QT -= gui" to .pro file
4. Added "LIBS += -lmingw32 -mwindows" to .pro file
5. Added "QT_CXXFLAGS+=-mwindows" to .pro file
6. Added "CXXFLAGS += -mwindows"
7. Added "LIBS += -u _WinMain@16" to .pro file
8. Reversed library order (I get the same error but from a cygwin library)
9. Added explicity path to libmingw32.a (although I think it found it)
10. Added "using namespace std" in the file with my main()
11. Added these two lines: "int WinMain@16();" and "intWinMain@16() { }"
12. Added these two lines: "int WINAPI WinMain(HINSTANCE inst, HINSTANCE prev, LPSTR cmd, int show);" and "int WINAPI WinMain(HINSTANCE inst, HINSTANCE prev, LPSTR cmd, int show) { return 0; }"
13. Removed all main() functions
14. Added "LIBS += -lmingw32 -mwindows"
15. Added "LIBS += -lgdi32 -lkernel32 -luser32 -lshell32 -lm"
16. Moved mingw32 libraries to beginning of LIBS

None of these solutions remove the "undefined reference to 'WinMain@16'" error.

Have I left anything off?

Run: qmake -project from command prompt then open the project and build it.
If this doesn't work, create a simple project that replicates the problem and upload it here.

Hmm ... that seemed to get me past the linking issue. Now it's saying that it's missing certain header files.

This seems strange to me because I thought the linking happened at the end.

My whole project file is different now, so it's hard to say what is different exactly.
