What is the expected behavior?
builds same as on linux

What do you see instead?

What version are you using?
experimental

On what operating system?
Window7 w/ msys 1.1 / gcc 4.6 32 bit

Please provide any additional information below.
linux cross build is able to produce working binaries.

We think this is fixed, if not, can you try to add the hash commit you are 
trying? 

thanks

Cross compiling for gprecise. Install mingw32 or mingw-w64. The cross tool is 
i586-mingw32- (IIRC) for mingw32 and i686-w64-mingw32- (win32) or 
x86_64-w64-mingw32- (win64) for mingw-w64

CROSS=x86_64-w64-mingw32- ../libvpx/configure --target=x86_64-win64-gcc

I haven't managed to reproduce the pthread error on linux though

Just to be clear, the issue I'm asking to be addressed is pthreads.

--disable-multithread should disable threads.

pthreads dont natively come with windows.  They can be added somehow, so it 
might be nice to have instructions on how.  But since vp9 doesnt support 
threads, its moot.

I'll see if I can find the holdouts.

Looks like your CL should work.  I was unable to build 'master' on Thursday.  
Which branch is your CL in?

It is in 'master'

Linux cross build works.  Steps taken:

sudo apt-get install yasm
cd ~

cd libvpx

Successfully compiled with
CROSS=i686-w64-mingw32- ./configure --target=x86-win32-gcc

but when using
CROSS=x86_64-w64-mingw32- ./configure --target=x86_64-win64-gcc
configure succeeded, while make (with -j8; w/o it the output is similar) got:
    [STRIP] libvpx.a < libvpx_g.a

The problem is due the w32pthreads library that can be optionally provided by 
mingw-w64. Sadly it is incomplete, the simplest solution is not just check for 
the header presence but also check if the library has the needed symbols.

Tried all the solutions in this thread to no avail under Win32 MinGW.

Re #15
Thats a long article with several problems/solutions.
As I work on libyuv, the scale.c compile error concerns me.

Can you clarify which parts of the article are relevant?
