V8Js on Windows

The V8Js PHP extension is primarily targeted at Unix platforms, especially GNU/Linux. However it is possible (and supported) to build on Windows, using Microsoft Visual Studio.

Building with MinGW or Cygwin is not officially supported; mainly since Google v8 does not support builds on Cygwin (and building it on Cygwin is currently broken).

Compared to installation on GNU/Linux it's way more tedious to install V8Js on Windows, since you need to compile PHP with all its dependencies beforehand.

You need to have Visual Studio 2015 (aka VC14), make sure to install the C++ compiler (which is not installed by default any longer).

Compiling v8

The Google v8 project already has excellent step-by-step guide on how to build with gyp.

As a short run through:

Then open a command prompt

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git 
fetch v8
git checkout 4.7.80.25
gclient sync
python build\gyp_v8 -Dcomponent=shared_library -Dv8_use_snapshot=0
CALL "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\vcvars32.bat"
msbuild build\All.sln /m /p:Configuration=Release

(alternatively start build/all.sln ... and build within the Visual Studio GUI)

Compiling PHP

Then follow the build your own PHP on Windows guide on the PHP wiki. Use Visual Studio 2015 with PHP7.

A quick run through:

Open "VS2015 x86 Native Tools Command Prompt"

cd \php-sdk
bin\phpsdk_setvars.bat
bin\phpsdk_buildtree.bat phpdev

mkdir vc14
mkdir vc14\x86
mkdir vc14\x86\deps
mkdir vc14\x86\deps\bin
mkdir vc14\x86\deps\include
mkdir vc14\x86\deps\lib
  • download PHP from http://php.net/get/php-7.0.1.tar.gz/from/a/mirror and unpack to below \php-sdk\phpdev\vc14\x86
  • from \v8\build\Release\lib copy icui18n.lib, icuuc.lib, v8.lib, v8_libbase.lib and v8_libplatform.lib to deps\lib folder
  • from \v8\include copy all v8*.h files to deps\include folder
  • copy v8-platform.h again to deps\include\include folder
  • download V8Js and unpack it into a separate directory below ext folder
  • make sure config.w32 file inside that folder defines version of the compiled v8

(still in "VS2015 x86 Native Tools Command Prompt")

cd \php-sdk\phpdev\vc14\x86\php-7.0.1\

buildconf
configure --disable-all --enable-cli --with-v8js
nmake

After nmake completes the php.exe is in Release_TS\ directory.

In order to try things out in place, copy over icui18n.dll, icuuc.dll and v8.dll file from \v8\build\Release folder to \php-sdk\phpdev\vc14\x86\php-7.0.1\Release_TS\ first.

Then run

Release_TS\php.exe -d extension=php_v8js.dll -d extension_dir=Release_TS\

Alternatively copy all stuff to c:\php\ (including the three DLL files from v8 build).
