Re: [v8-users] NewDefaultPlatform() unresolved external symbol
That just gives me other errors. I've looked at the
https://bugs.chromium.org/p/v8/issues/list and I really just think the
debug build is broken right now for win 10/MSVC.

Re: [v8-users] NewDefaultPlatform() unresolved external symbol
I followed the instructions. I've tried several different setups and it
just seems to me that V8's debug setup is screwed up. (Release build is
fine.)

Re: [v8-users] call javascript function from c++
Yes, the examples are horribly written and hard to understand.
And I don't believe any of them covered this:
// get the function
v8::Local global = context->Global();
v8::Local function_value1 =
global->Get(v8::String::NewFromUtf8(isolate, "StartNamespace"));
v8::Local a = v8::Local::Cast(function_value1);
v8::Local function_value2 =
a->Get(v8::String::NewFromUtf8(isolate, "cppTalkTo"));
v8::Local function1 =
v8::Local::Cast(function_value2);
// call it
v8::Local js_result1;
js_result1 = function1->Call(context, global, 0, nullptr).ToLocalChecked();
Unless there is a better way, please consider my original post answered.

[v8-users] call javascript function from c++
Let's say you compile and run code:
var StartNamespace =
{
cppTalkTo: function () {
// some code
}
};
StartNamespace.init();
After you compile and run the above code how could you call cppTalkTo from
C++? Whats the C++ functions for that?
Basically I want to:
v8::Script::Run
v8::Script::Compile
At this point how do i get the cppTalkTo v8::Handle and
then call the function?

[v8-users] InitializeICUDefaultLocation
What is the proper way to do this function? I just can't get it to work. My code: const char * exec_path = "C:\\Users\\Joe Smack\\Documents\\Visual Studio 2017\\Projects\\v8 console test\\v8 console test"; const char * icu_data_file = "icudtl.dat"; V8::InitializeICUDefaultLocation(exec_path, icu_data_file); This code is giving me an exception in the function InitializeICU (called from InitializeICUDefaultLocation) when it gets to FILE* inf = fopen(icu_data_file, "rb"); (line 95) The debugger says icu_data_file = icudtl.dat i copied icudtl.dat to the project directory from v8 directory.
