Hi..

Is it possible to reconfigure gcc after it being built?
Like mingw-w64 is taking from its own include directory.
I want it to point to windows sdk instead. Is it possible?
I got errors i couldn't understand when i set the -I (i letter) and the -l
(small letter L)
options on gcc compiler. is it of any use if i show you? thanks..

It's mentioned in the manual that the compiler options l and I have
precedence over the
configuration. so how come it's complaining;

C:\mystuff\delme>gcc mingw.c -l "C:\Program Files (x86)\Windows
Kits\10\Lib\10.0.22621.0\um\x64\user32.lib" -I "C:\Program Files
(x86)\Windows Kits\10\Include\10.0.22621.0\um"

      |          ^~~~~~~~~~~~~~~

i don't even know what the error means! it's saying something along the
lines of:
 1 file included from, and then the next from, which means what? etc.. and
then after mingw.c:4: there is what?

all i know is that windows.h was included in my project, and then i presume
windef.h was included from within the windows.h file?
how did it achieve changing directories? windows.h is in the includes i
mentioned in the compiler options..etc.. there's also a further
proof that it shouldn't have switched folders,that winnt is still in the
specified include folder which is maybe included from windows.h...
can you see the contradiction between last two files specified ? and first
file(minwinder.h)?

sorry if i'm not clear or if i'm not asking the right person :)
the code:


#include <stdio.h>
#include <windows.h>

int main(int argc, char *argv[])
{
  printf("asdklfjasldfka\n");
  MessageBoxA(NULL, "hi.....", "caption", MB_OK);
  return 0;
}
