Thank you Jochen, Ben, Louis for your help. It's all up and running now.
Just for posterity, and to help the person who comes after me, here are a
few quick things that slowed me down along the way: (I am using Visual
Studio 2013 Update 4 on Windows 8.1 Pro 64 bit. compiled in 32 bit mode
for now for V8 in VS2013) :
1. If you get lots of VS2013 linker error "LNK2005: _isdigit already
defined in MSVCRTD.lib(MSVCR120D.dll)" etc etc errors when you try to
compile your hello world program, make sure that under Project ::
Properties :: Configuration Properties :: C/C++ :: Code Generation ::
Runtime Library you have the same version of the library for your hello
world program that you used to compile your V8 library (I used /MTd -
Multi-threaded Debug on both).
2. If you get "error LNK2019: unresolved external symbol "public:
__thiscall v8::HandleScope::HandleScope(class v8::Isolate *)"
(??0HandleScope@v8@@QAE@PAVIsolate@1@@Z) referenced in function _wmain"
etc. errors... Under Project :: Properties :: Configuration Properties ::
Linker :: Input :: Additional Dependencies make sure the following files
(with whatever path you used for your V8) are included:
C:\Dev\v8\build\Debug\lib\v8_base.lib
C:\Dev\v8\build\Debug\lib\v8_libbase.lib
C:\Dev\v8\build\Debug\lib\v8_libplatform.lib
C:\Dev\v8\build\Debug\lib\v8_nosnapshot.lib
C:\Dev\v8\build\Debug\lib\icuuc.lib
C:\Dev\v8\build\Debug\lib\icui18n.lib
ws2_32.lib
winmm.lib
3. and of course make sure that under Project :: Properties ::
Configuration Properties :: C/C++ :: General :: Additional Include
Directories you add the path to your v8\include directory and your
v8\include\libplatform directories.
4. When you are following the directions for downloading the V8 source code
and running GYP, make sure you FIRST install all the tools (git, svn (I
used TortoiseSVN), MSys + MinGW (remember to create the fstab file in
C:\MinGW\msys\1.0\etc\ file), Python 2.7.x) and verify that they are
working and in your cmd shell path.
5. Make sure when you are in your Windows CMD shell that your path has no
spaces, no parenthesis, etc., AND as mentioned in #4, that it includes all
the paths to the appropriate tools. Here is the full path that ended up
working for me.
PATH=C:\Dev\Python27\;C:\windows\system32;C:\windows;C:\windows\System32\Wbem;C:\windows\System32\WindowsPowerShell\v1.0\;C:\Dev\Git\cmd;C:\Dev\depot_tools;C:\MinGW\bin;c:\MinGW\msys\1.0\bin;C:\Dev\TortoiseSVN\bin
6. Here is the exact hello.cpp file I used (thanks Jochen) : (this worked
11/18/2014, but it seems that the required startup initialization code for
V8 changes occasionally, so check to make sure this is up to date):
// Learning_V8_001.cpp : Defines the entry point for the console
application.
//
#include "stdafx.h"
#include "v8.h"
#include "libplatform.h"
using namespace v8;
int _tmain(int argc, _TCHAR* argv[])
{
// Initialize V8.
V8::InitializeICU();
Platform* platform = platform::CreateDefaultPlatform();
V8::InitializePlatform(platform);
V8::Initialize();
// Create a new Isolate and make it the current one.
Isolate* isolate = Isolate::New();
{
Isolate::Scope isolate_scope(isolate);
// Create a stack-allocated handle scope.
HandleScope handle_scope(isolate);
// Create a new context.
Local<Context> context = Context::New(isolate);
// Enter the context for compiling and running the hello world script.
Context::Scope context_scope(context);
// Create a string containing the JavaScript source code.
Local<String> source = String::NewFromUtf8(isolate,
"a={'first':4,'second':66}");
// Compile the source code.
Local<Script> script = Script::Compile(source);
// Run the script to get the result.
Local<Value> result = script->Run();
// Convert the result to an UTF8 string and print it.
String::Utf8Value utf8(result);
printf("%s\n", *utf8);
char ch; scanf("%c", &ch, 1);
}
// Dispose the isolate and tear down V8.
isolate->Dispose();
V8::Dispose();
V8::ShutdownPlatform();
delete platform;
return 0;
}
can't think of anything else off the top of my head. Hope this helps.
