libv8 is currently not supported on Windows. It should be doable in theory, and we'd love to have somebody contribute this, and would be very open to helping out, but we know very little indeed about the Windows platform.

so should I change my platform?

Not supporting windows make me so sad~~, I can't change my plateform. I've installed ubuntu linux as the second system, but I can only connect to network by a software that only supports windows.

I'm not happy about it myself. It's not about any ill will or malice towards Windows, but we just don't have access to the computers. If somebody were to donate a windows box, or a copy of windows with legit licences for the OS and the devtools required, then that would be a great start, but as it stands, we're stuck in the water.

I'm working in Windows on VirtualBox with Debian. One monitor for Debian and one for Windows... Internet works like just plug an another computer on lan, you can even copy/paste between systems and it works pretty fine for me for that kind of problems. :)

On windows 7, with ruby193 I installed python27, I added to the PATH variable the python's folder, I wrote gem install libv8 in the console and libv8 was succesfully installed
from libv8.
diegomesata, can you elaborate more on this? which path variable? and where is it?
I am using rubygems1.8.17 and python 2.7
from libv8.
You can find the PATH variable in Windows in Control Panel -> System -> Advanced System Configuration -> Environment Variables.
My PATH variable is: C:\Ruby192\bin;C:\Python27
In a Command Prompt with Ruby, you can set the variable for that console using the command
SET PATH=C:\Ruby192\bin;C:\Python27
You can check the values using the command
PATH
Hope this helps

Ohh dont forget to install the Ruby Dev Kit https://github.com/oneclick/rubyinstaller/wiki/Development-Kit
from libv8.
diegomesata, thanks a lot. it works
from libv8.
@diegomesata Does that mean you able to get therubyracer to install?
from libv8.
hello cowboyd, no, I can't install therubyracer (yet). I'm working on windows 7 64 bits, the error I got trying to install the gem is: g++.exe: c:/Ruby192/lib/ruby/gems/1.9.1/gems/libv8-3.3.10.4/lib/libv8/build/v8/libv8.a: No such file or directory
Looks like some process building libv8 by hand in a static way for windows could fix the issue, like suggest http://code.google.com/p/pyv8/wiki/HowToBuild that was getting a similar error on osx.
My current project doesn't need therubyracer, so, in the Gemfile I commented the #gem 'therubyracer'
from libv8.
I'm having the same problem as @diegomesata. I actually could install the libv8 gem after installing python 2.7.x but the therubyracer gem still won't install because there is no compiled binary for libv8.a, so the install process gives me the same error as specified above.
If someone builds/compiles this file for windows 7 64 bit environment, let me know because I think it will solve the problem!
from libv8.
@cowboyd I'll be glad to help with compiling it if you could point out what I should be doing - I have win7 764bit
you can email me at yossale [at] gmail

Same problem here.

If I try installing libv8 in command line with above input, I get a window error dialogue with title 'patch.exe' and a text saying that 'patch.exe has stopped working'. The console does not display any other information, and it claims it has successfully installed libv8, which it actually isn't.
After on, if I do bundle install, 'therubyracer (0.10.1)' will still fail to install with a error message 'libv8.a' missing.
I need 'therubyracergem' to use 'twitter-bootstrap-rails' gem.
from libv8.
For those interested, I'm converting libv8 to use the GYP build instead of scons. @cielo @yossale Can you build from master?
from libv8.
Hi, if I build from master, it fails with below error message.

I am new to rake and gem so I have not done any manual compiling before. I am not sure if I am doing things right.

I should mention that you will need make, subversion and python installed in order to build.
from libv8.
I am sure that I have 'git', 'svn', 'python' command added to the path, but I do not think I have 'make'.
I uses ruby dev kit (http://rubyinstaller.org/add-ons/devkit/) which compiles some of the gems that requires C based compile.
from libv8.
I don't have experience with it, but ruby extensions require make to compile, so it must be on the system somewhere. Perhaps devkit has it stashed away somewher off the main path?
from libv8.
@cielo I've again update to a 3.11 which should have several enhancements to the upstream build. Any chance you can get it to work?

It still produces an error.

Here it is, but in libv8 it's now called libv8_include_path
from libv8.
yes, we need to patch older versions of the rubyracer because it is using the newer version of libv8, not the one that is in the bundle.
This is why in the latest version of the rubyracer, we explicitly activate a compatible version of libv8: https://github.com/cowboyd/therubyracer/blob/master/ext/v8/build.rb#L6
However, if you can get libv8 to build, then we're really close. Tell me, can you build therubyracer from master?

this would indicate that libv8 did in fact, not build properly. Have you tried just manually building it yourself? This version of therubyracer does not actually require the libv8 gem. If you can get libv8 installed into your system somewhere so that -lv8 will properly link
from libv8.
I didn't see any error while installing gem because it's fails silently. Here is the fix
Actual error is
...

I'm actually not sure if it's possible to build libv8 on windows with Mingw, because V8 gyp-files on windows generating MSVC project. Or am I wrong?
All I could find about building V8 with MinGW, mention Scons. So those are old instructions. But SConstruct still there.

fyi, you don't need to use the libv8 gem to build therubyracer. You can also install from source as a shared library.

I can't build v8 on windows with mingw. So this mean I can't build therubyracer anyway. Or am I wrong?
Building libv8 gem is the same as build v8 itself, because it's internally calls v8 builder (make ia32.release
).
from libv8.
There is hardcode in GYP: for windows it supports only one toolchain msvs
. Didn't test, but I believe that msvs
binaries are incompatible with MinGW. But it is possible to use those binaries through ffi
. There is no support cross OS compilation in GYP (but there is cross ARCHITECTURE compilation). Chromium team won't implement those features, but they are "happy to accept patches". I'm personalty don't want to dig in GYP source to get this work.
Another option: is to use build with scons
. But scons
build is deprecated by Chromium team.
I believe that easiest way here: try to do cross compilation with scons
. There is old patch to enable cross OS compilation with scons.

Yikes! It does look like there is some fairly fresh work happening in this area to get it working, which you probably saw on google. Is this you or somebody else? http://code.google.com/p/v8/issues/detail?id=2197
from libv8.
It's somebody else. I get further then him. I was able to run v8 build against MinGW. But it doing nothing (make[1]: Nothing to be done for 'all'.
).
from libv8.
I builded v8 on windows with following command scons os=win32 toolchain=gcc library=shared
. As the result i get bunch of files in obj\release
folder and v8.dll
, v8.lib
, v8.a
, v8preparser.a
, v8preparser.dll
in the root.
But it seems didn't produce libpreparser_lib.a
, libv8_base.a
, libv8_nosnapshot.a
, libv8_snapshot.a
from libv8.
Hmm... it looks like the scons build does not generate two separate static libraries for base and snapshot. But that's OK. I think you just need to link directly against v8.a
and you should be fine.
from libv8.
I successfully build therubyracer
on windows see rubyjs/therubyracer#172
from libv8.
Another option is to compile v8 with Visual Studio Express. And try to link against it. According to this post it's possible.
from libv8.
Solution found! 100% working...
The reason for all of these problems is the therubyracer-0.11.0beta1-x86-mingw32.gem and the v8.dll.
I have complied the necessary dlls and gem files and upload them to github.
download the package and follow the instructions...
https://github.com/hiranpeiris/therubyracer_for_windows
good luck :-)
from libv8.
I was able to compile a static library on Windows with VS 2008 express without any patching whatsoever. Not sure if I can link therubyracer against it with mingw's linker though. @cowboyd do you think this is practical enough to be worth the time (as in do you think you can provide Windows binaries if we are able to automate the compilation process, having in mind the required stuff below)?
Prerequisites for compilation:
- Python 2.* (to generate a VS project with gyp)
- Subversion (to checkout a special version of cygwin)
- VS 2008 Express free (to build the project)
Also it would be great if somebody with more than my 30 minutes of experience with C++ on Windows would lend a hand 😄
from libv8.
I think simple way of installation is better than compile it from the
source...
that's why therubyracer for windows is out-there...

@hiranpeiris I think we can all agree that the simplest installation is the way to go. The simplest way to get there is to have a fully automated build from source that can then be leveraged to construct binary releases. That's not to detract from the work you have done at all. I think it's awesome, and I will be sure to point Windows users to your project.
@ignisf If you can automate the build, then I'd be happy to provide windows binaries. A Vagrantfile
or image with the appropriate toolchain would be boss.
from libv8.
The question if the ibv8 builded with VS 2008 will be compatible with Ruby builded with MinGW. I believe not. I saw post about converting VS binaries to MinGW (or make them compatible). @luislavena can you consult us about this question?
@hiranpeiris,@ignisf see options and those PRs #40, #41
from libv8.
libv8 builded with VS 2008 will be compatible with Ruby builded with MinGW
If libv8 is build as static object, it might be possible to link, but also will use other CRT function references that is not available by basic MSVCRT.
If libv8 is build as shared resource: it will link to a different version of the CRT and that is a recipe for crash.
The simplest way to get there is to have a fully automated build from source that can then be leveraged to construct binary releases.
I don't think scons support cross-compilation that can be used to produce libv8 in linux that targets Windows.
The best approach is introduce changes to this project that allow native compilation of libv8 static library and release those as x86-mingw32
gems, which later can be used to link therubyracer.
from libv8.
Please provide a Windows version. Unix is great, but many of us need Windows support.

@cowboyd @stereobooster ,i want to install libv8 gem of lastest version (3.16.14.3) on windows also, after getting ready v8 and dependencis ,when i build v8 and print (make[1]: Nothing to be done for 'all'.).
in the console too, and you say scons os=win32 toolchain=gcc library=shared.
,and the command will occupy error like ImportError: No module named utils: File "D:\work\libv8\vendor\v8\SConstruct", line 36: import js2c, utils
, it seem not support scons already now,can you give me advice,Thanks

Hoping somebody with sufficient windows knowledge will follow up on #126
from libv8.
This error is about a libv8-3.11.8.17\ext\libv8\builder.rb script.
On line 60 we can see this code:
`python -c 'import platform; print(platform.python_version())'`.chomp
This is a wrond python command syntax in Windows. You should use a double quotes, like this:
`python -c "import platform; print(platform.python_version())"`.chomp
After fixing this script, you should run gem install with "-l" (use local only) key. If you don't, gem will download a script with an error again.
