Dear all.
I already tried to compile on recent MinGW, but I met same result.
In fact, it is caused by recent GCC version 4.8.1.
I tried to figure out why for a hour, but I could not find the reason.
(It could be a compiler bug, so it should be analyzed on assembly level.)
If someone find the reason, please let me know.
You can use recent MinGW, if you downgrade GCC version.
# mingw-get install gcc-core=4.7.2-1
Thanks.

Title : [SDK/Emulator] Building emulator with latest MinGW
Hi, all
Currently I'm tying to setup emulator build environment on a new windows xp 32 machine. I'm using latest
MinGW - http://sourceforge.net/projects/mingw since there's no other choice there.
Emulator builds successfully, however, there're problems running it, there're crashes. I've found the cause
of first crash:
qemu/tizen/src/emulator.c:print_system_info - strftime(timeinfo, sizeof(timeinfo), "%Y/%m/%d %H:%M:%S", tm_time);
It crashes here because in latest MinGW time_t is defined to be 8-byte long, so fix is simple:
gettimeofday(&tval, NULL);
time_t tmp = tval.tv_sec;
tm_time = localtime(&tmp);
strftime(timeinfo, sizeof(timeinfo), "%Y/%m/%d %H:%M:%S", tm_time);
After this it boots further, but crashes later in:
Program received signal SIGSEGV, Segmentation fault.
_fu797____stack_chk_guard () at block.c:3864
3864 BlockDriverState *bs = acb->common.bs;
(gdb) bt
#0 _fu797____stack_chk_guard () at block.c:3864

#3 0x7c82ff99 in KERNEL32!ConvertThreadToFiber ()
from C:\WINDOWS\system32\kernel32.dll
Cannot access memory at address 0xbaadf011
The reason may be changed time_t size or something else...
Does anyone know something about this ? Is there a workaround ? Fixing those problems is taking too long already,
is there a way I can build correct emulator image on a fresh windows xp 32 machine ?
