Hi, I must be missing something obvious. Can anyone tell me why this
lightly modified Hello World program crashes? (e.g. "terminated by signal
SIGSEGV (Address boundary error)")
#include <v8.h>
using namespace v8;
int main (int argc, char* argv[])
{ Isolate* i = Isolate::GetCurrent();
HandleScope _ (i);
// These 3 lines are taken basically from v8.h docs on FunctionTemplate
v8::Local<v8::FunctionTemplate> t = v8::FunctionTemplate::New();
t -> Set ("func_property", v8::Number::New(1));
t -> GetFunction (); // crash in here
v8::Handle <v8::Context> context = v8::Context::New (i);
Context::Scope context_scope (context);
Handle <String> source = String::NewFromUtf8 (i, "hello world");
Handle <Script> script = Script::Compile (source);
Handle <Value> result = script -> Run();
String::Utf8Value utf8 (result);
printf ("%s\n", *utf8);
return 0;
}
If I put the offending 3 lines after the context initialization, it works.
However, that's a problem -- all my interesting binding code (just like
all the binding code in the examples) needs to happen BEFORE the context
is set up, right? I want to decorate a global object and pass that as the
3rd argument to Context::New(). What I actually want to do are things like
this, found in the node addon sample code, but is is the case that I just
can't do things like this until after the context is already in place?
void MyObject::Init(Handle<Object> exports) {
Isolate* isolate = Isolate::GetCurrent();
// Prepare constructor template
Local<FunctionTemplate> tpl = FunctionTemplate::New(New);
tpl->SetClassName(String::NewFromUtf8(isolate, "MyObject"));
tpl->InstanceTemplate()->SetInternalFieldCount(1);
// Prototype
NODE_SET_PROTOTYPE_METHOD(tpl, "plusOne", PlusOne);
constructor.Reset(isolate, tpl->GetFunction());
exports->Set(String::NewFromUtf8(isolate, "MyObject"),
tpl->GetFunction());}
thanks,
Brandon
