I'm compiling with MinGW-w64 and the MSYS environment. I used the following configure options:
./configure --disable-dynamic-x86 --disable-fpu-x86 --host=x86_64-w64-mingw32 --target=x86_64-w64-mingw32

The only thing i can't figure out is the error in cdrom_aspi_win32.cpp.

1In file included from core_dynrec.cpp:136:

3core_dynrec/cache.h:599: error: cast from 'Bit8u*' to 'long int' loses precision
4make[4]: *** [core_dynrec.o] Error 1

Changing "long int" to "long long int" fixes this.

I don't know how to properly fix this error. I commented out the code to get passed the error.

Changing "DWORD" to "long long" fixes this.

Changing _WIN32_IE version from "4.00" to "5.02" fixes this.

I have a test build if anyone wants to try it.

The recompiler doesn't work under 64bit windows so you can disable it
through configure parameters, and the aspi interface should not be used
as well (just hack around that).

The _WIN32_IE thing is some mingw header strangeness but i don't remember
if i've ever properly worked around that. Your hack is fine though.

In any case for maximum speed use a 32bit compile.

Are there any plans to support the recompiler on 64-bit Windows at some point?

Not really as the direct recompilation is still much faster.

So then is there hope for direct recompilation?

Oh and i thought i 'd mention 64-bit does see a nice performance increase when doing low level emulation of 3d graphics processors, MAME is a good example. Low level emulation of 3DFX in DOSBOX would be sweet.

For me x86 to x86 is direct dynamic recompilation, everything else is more
complex and less performant like x86 to x64 recompilation. So yes, it is possible
(like under linux 64bit recompilation is working fine) but will not reach the
speed of the x86 to x86 approach.
