问题描述

限时删除!!

我似乎无法弄清楚如何启动 V8.我有这个代码:

I can't seem to figure out something getting V8 started up. I have this code:

if (!_V8Initialized)
{
    v8::V8::InitializeICU();

    v8::V8::InitializeExternalStartupData("x86\\"); // (this loads ok, I checked)

    auto platform = v8::platform::CreateDefaultPlatform();
    v8::V8::InitializePlatform(platform);

    v8::V8::Initialize();

    _V8Initialized = true;
}

auto params = Isolate::CreateParams();
params.array_buffer_allocator = ArrayBuffer::Allocator::NewDefaultAllocator();
_Isolate = Isolate::New(params);

但我收到此错误:

在 V8.Net.Console.exe 中 0x0000000000000000 处抛出异常:0xC0000005:访问冲突执行位置0x0000000000000000.

这里似乎失败了:

explicit SnapshotData(const Vector<const byte> snapshot)
  : SerializedData(const_cast<byte*>(snapshot.begin()), snapshot.length()) {
    CHECK(IsSane()); <-- THIS FAILS
}

我遵循了这里的源代码(大部分):https://chromium.googlesource.com/v8/v8/+/branch-heads/4.8/samples/hello-world.cc

I followed the source code here (for the most part): https://chromium.googlesource.com/v8/v8/+/branch-heads/4.8/samples/hello-world.cc

...但我不知道为什么我似乎收到了一个空错误.我一定是遗漏了什么……

... but I'm not sure why it seems I'm getting a null error. I must be missing something...

推荐答案

没关系,我似乎总是在发布到 SO 后弄清楚事情,哈哈.事实证明我是从 x86 目录而不是 x64 目录加载的(鉴于 V8_Net_Proxy_x64.dll,我应该猜到了!哈哈).

Nevermind, I always seem to figure things out AFTER posting to SO, lol. It turns out I was loading from the x86 directory and not the x64 directory (which I should have guess given the V8_Net_Proxy_x64.dll! lol).

我打算删除这个问题,但无论如何我都会把它留在这里,以防其他人在半夜睡着了.;)

I was going to delete the question, but I'll leave this here anyhow in case someone else falls into this in the middle of the night half asleep. ;)
