[x264-devel] x86_64 build command

[Edward Richards]

Hi all,
I'm embarrassed to have to ask but what it the command line to build x264 as
64 bit on windows?

I configured using the commands below but it makes MMX instructions. From
what I can tell you can't have MMX in a 64bit program (well that's what the
MSDN help says anyhow). When I run it I crash on a XMM0 related opcode.

Currently I build using this configuration but it causes the above MMX
problem.

#!/bin/sh
./configure \
	--cross-prefix=/mingw/bin/x86_64-w64-mingw32- \
	--sysroot=/mingw/x86_64-w64-mingw32 \
	--host=x86_64-pc-mingw32 \
	--extra-cflags=-m64 \
	--enable-debug \
	--enable-win32thread \
	--enable-static \
	--extra-cflags=-I../static64/include \
	--extra-ldflags=-L../static64/lib \
	--prefix=../static64

I added -mno-mmx but then I get 

$ make
