Ready for use V8 build for Win 32-bit

[treck]

I need to use v8 engine for my C++ project. Could someone share  here ready for use binaries for platform Windows 32-bit? I tried compile it myself but i get error. If someone is cuirious this error it's here (my platform Windows 7 64-bit) :

python.exe build\gyp_v8 -Dtarget=ia32 -Dcomponent=shared_library
Updating projects from gyp files...
  File "<string>", line 1
    import sys; print sys.byteorder
                        ^
SyntaxError: invalid syntax
gyp: Call to 'python -c "import sys; print sys.byteorder"' returned exit status
1.

Thanks in advance.

Google groups decided to put my answer in a different thread =) It looks like you have Python 3.x installed, which changed various things. The V8 scripts work with Python 2.x, so I suggest installing https://www.python.org/download/releases/2.7.6/ and trying again.

Thanks, it was problem with version of my Python.
I tried compile it using my Visual Studio 2012 and it failed so I used MinGW to compile v8 but it failed too... i get such error (i replaced some parts of paths with (...) ) :

$ make ia32.release -j8
PYTHONPATH="/e/(...)/v8/tools/generate_shim_headers:/e/(...)/v8/build::/e/(...)/v8/build

                      -Dv8_target_arch=ia32 \
                       \
                       \

You need VS 2013, V8 is a C++11 project. VS 2015 should work as well,
I think, but MinGW is not supported.

I compiled it in VS 2013 and I got a lot of warnings. I tried build hello world program from https://developers.google.com/v8/get_started in VS 2013 and it crashes with Access violation error: http://i.imgur.com/ohBpbLY.png http://i.imgur.com/qvJUMmT.png

Ok, Now I've used code from https://github.com/v8/v8-git-mirror/blob/master/samples/hello-world.cc and it worked.

Regarding the warnings: v8 itself is warning-free (checked on our build bots), the warnings you see are triggered by the ICU library, which we just pull in (like everything under v8/third_party).
