[Matthew]

When I compiled v8.sln, the message below is displayed,
2>Processing js files...
2>Traceback (most recent call last):
2> File "..\js2c.py", line 364, in <module>
2> main()

2>IOError: [Errno 2] No such file or directory: 'CORE'
2>Project : error PRJ0002 : Error result 1 returned from 'C:\Windows

Hi Matthew,

I'm not experienced in windows build system at all but I have already
run into the same problem on linux.
I think you should modify the tools/visual_studio/js2c.cmd:6 line:
remove the %TARGET_DIR%\natives-empty.cc argument.
The generating of the natives-empty.cc file isn't needed anymore.

Regards,
Peter

Hi,
Same problem here (windows, at revision: 7679).
I removed the argument in js2c.cmd
but when linking v8_mksnapshot there are unresolved externals
reported; 4 entries related with NativesCollection
Ale.

Hi,

An experimental-libraries.cc file need to be generated for linking
v8_mksnapshot.
You can generate it with a similar command like at
tools/visual_studio/js2c.cmd:6.
Try to add the following line to the js2c.cmd file:

%PYTHON% ..\js2c.py %TARGET_DIR%\experimental-libraries.cc EXPERIMENTAL
%SOURCE_DIR%\macros.py %SOURCE_DIR%\proxy.js

I'm not sure it's correct because I couldn't try it. Probably you should
add the experimental-libraries object to the build system too.
The idea is based on the solution in src/SConscript (look
"experimental_libraries" term up in the SConscript file).

Regards,
Peter

[Alejandro F. Reimondo]

Thank you Peter for the information.
making teh changes you suggested, and
replacing "natives-empty.cc" with "experimental-libraries.cc"
under "v8/generated files" and "v8_snapshot/generated files"
makes the solution file compilation success in debug
and release mode (svn revision 7695).
cheers,

After modification as Peter suggested, my js2c.cmd includes the following items,
---------------------------begin------------------------------
@echo off
set SOURCE_DIR=%1
set TARGET_DIR=%2
set PYTHON="..\..\..\third_party\python_24\python.exe"
if not exist %PYTHON% set PYTHON=python.exe

%PYTHON% ..\js2c.py %TARGET_DIR%\experimental-libraries.cc EXPERIMENTAL %SOURCE_DIR%\macros.py %SOURCE_DIR%\proxy.js

---------------------------end----------------------------

However, I even got more errors , as follows,
3>mksnapshot.obj : error LNK2019: unresolved external symbol "public: static int __cdecl v8::internal::NativesCollection<0>::GetBuiltinsCount(void)" (?GetBuiltinsCount@?$NativesCollection@$0A@@internal@v8@@SAHXZ) referenced in function _main

Hi,

I am afraid that the Visual Studio project files in the tools/visual_studio directory has not been updated recently, and therefore are not really usable. We are planning to remove these files and instead support generating Visual Studio files from GYP files in the same way as is used by Chromium.

To generate Visual Studio project files from GYP take a look at the README.txt in the build directory.

Sorry for the inconvenience.

Note that SCons is still the main build tool for V8.

Regards,

Søren

My V8 revision: 7697
Does anyone know how to compile v8 code on Windows?

Hi Mads,

Thanks.
However, If you compile V8 code( revision: 7697) by exactly followed http://code.google.com/p/v8/wiki/BuildingOnWindows , you can NOT compile success.

I found no problems building using SCons. I have Visual Studio 2008, Python 2.7 installed in C:\Python27 and Scons 2.0.1 on top of that.

From a "Visual Studio 2008 Command Prompt" I issue:

> set PATH=C:\Python27;C:\Python27\Scripts;%PATH%

> scons sample=shell env="INCLUDE:%INCLUDE%,LIB:%LIB%,PATH:%PATH%"

> shell

V8 version 3.3.3 (candidate)

> 1+1

2

>

Please provide some more information on the failing compile.

Regards,

Søren

Add the experimental-libraries.cc file (in target dir)

 to v8 and v8_snapshot projects.

That makes a success on my side.

I attached an image with my project tree.

Ale.

V8 revision: 7697 should contain some errors(I guess v8.sln causes the problem).

When I used VS2005 to compile V8 by followed http://code.google.com/p/v8/wiki/BuildingOnWindows , VS2005 complained the errors below,
1>virtual-frame-heavy.cc
1>c1xx : fatal error C1083: Cannot open source file: '..\..\src\virtual-frame-heavy.cc': No such file or directory
...

After I deleted the files(virtual-frame*, register-allocator* ...) from v8.sln, the following errors were occurred,

2>Processing js files...
2>Traceback (most recent call last):
2> File "..\js2c.py", line 364, in <module>
2> main()
2> File "..\js2c.py", line 361, in main
2> JS2C(source_files, [natives], { 'TYPE': type })
2> File "..\js2c.py", line 294, in JS2C
2> lines = ReadFile(filename)
2> File "..\js2c.py", line 56, in ReadFile
2> file = open(filename, "rt")
2>IOError: [Errno 2] No such file or directory: 'CORE'
2>Project : error PRJ0002 : Error result 1 returned from 'C:\Windows\system32\cmd.exe'.

Alejandro said he "makes a success". I want to know he choosed which V8 revision to compile.
