As a starting point, have you tried doing a hello world with just
windows.h included? There very well may be a regression that broke
something that is in windows.h.

[Tinycc-devel] Why doesn't this work in TCC?

2017-03-31 Thread Ben Hutchinson 
I just tried this code:

#include 
void _start(void){
HWND wnd;
HDC dc;
wnd = 0;
dc = GetDC(wnd);
ReleaseDC(wnd,dc);
ExitProcess(0);
}




But then when I compiled it, I got this error:

tcc: error: undefined symbol '_GetDC@4'
tcc: error: undefined symbol '_ReleaseDC@8'




I don't know where it's getting those errors. The windows.h include file is
supposed to include all the correct definitions of all the Windows API
functions. And the ones that aren't directly defined in windows.h are
defined in other include files that windows.h has included in itself (there
are other #include statements in windows.h). So they should ALL be defined,
but these 2 very common ones for working with graphics, have either not
been defined, or have been incorrectly defined (some kind of bug in one of
the include files).

Can somebody here please tell me exactly why it's not working?
