[pypy-dev] Build pypy 1.6 on Windows XP with MinGW: can't find ffi.h

[Caleb Hattingh]

Hi

This is a really silly thing, but I am hoping someone who has done
this before can just give me the one-liner answer.

I am trying to build pypy 1.6 on Windows XP using MinGW (in an MSYS
environment).   The build gets started, and I see a bit of Mandelbrot,
but when the time comes for JIT, I get an error which I will reproduce
below.  I am following the too-terse instructions at the bottom of
this page:

http://codespeak.net/pypy/dist/pypy/doc/windows.html

I have made sure that my newly-built libffi-5.dll is on the system
path, but I doubt that matters for translation.   The instruction that
I run is

$ pypy.exe translate.py -Ojit --cc=mingw32

(Note that the help page only uses a single hyphen as in
"-cc=mingw32", which doesn't work, that should be fixed on the page).
The error that I see is the following:

================================================================================

I have tried placing ffi.h (and ffi_common.h and ffitarget.h) in
various strategic places, but to no avail.   I could figure it out on
my own eventually, but perhaps someone could save me a little time?
In exchange, I would be happy to write a more detailed doc section for
building pypy on windows from source using mingw.

kind regards
