tcc: error: undefined symbol '_GetConsoleWindow@0'

Question

I'm making a program in C/C++ which must run hidden using this code:

#define _WIN32_WINNT 0x0500
#include <windows.h>
int main(){
    HWND hWnd = GetConsoleWindow();
    ShowWindow(hWnd, SW_HIDE);
    . . .
}

I really want to use tinyc to compile it because it's much better than gcc (almost, the final executable is much tiny than gcc).
The point is that when I try to compile it using:

tcc PROGRAM.c -luser32

It makes an error which says:

tcc: error: undefined symbol '_GetConsoleWindow@0'

But when I use gcc it works! I think I have a missed library but I don't know which one.
Please, some help :)

Answer 1

According to MSDN, GetConsoleWindow is located in Kernel32.dll

Try:

tcc PROGRAM.c -luser32 -lkernel32

---

EDIT:

tcc's kernel32.def is missing the export for GetConsoleWindow.

Append the string GetConsoleWindow at the end of the def file located in the lib directory inside tcc's installation folder.

Answer 2

remove gdi32.def kernel32.def msvcrt.def user32.def files from C:\tcc\lib; remove all .def files from C:\tcc\lib

#include <windows.h>
