小编Opo*_*sum的帖子

我正在努力让Clang在Windows上工作,最终使用Qt Creator进行开发,看看它是否是Visual Studio的可行替代品.

我LLVM和3.2锵(SVN版本163238),使用编译MinGW的W64(mingw-w64-bin_i686-mingw_20111220.zip)和还指出,海湾合作委员会的C++头文件目录加入AddMinGWCPlusPlusIncludePaths("D:/Code/mingw/lib/gcc", "x86_64-w64-mingw32", "4.7.0");到clang/lib/Frontend/InitHeaderSearch.cpp,虽然我认为这可能不是最上调迄今为止的方法.无论如何,Clang似乎找到了大部分标题.

但是,在编译简单的Hello World时:

#include <iostream>
int main(int argc, char* argv[])
{
  std::cout << "test\n";
  return 0;
}

使用clang++ main.cpp我得到这个错误:

In file included from main.cpp:1:
In file included from D:/Code/mingw/lib/gcc/x86_64-w64-ming32/4.7.0./include/c++\iostream:39:
In file included from D:/Code/mingw/lib/gcc/x86_64-w64-ming32/4.7.0./include/c++\ostream:39:
In file included from D:/Code/mingw/lib/gcc/x86_64-w64-ming32/4.7.0./include/c++\ios:39:

      'wchar.h' file not found

因此,Clang显然发现了几个C++标题,iostream但未能找到wchar.h.事实证明,这wchar.h是位于.../include/c++\tr1Clang不寻找的地方.将这些TR1标题移到一个目录中也无济于事.

我在这做错了什么？gcc C++库是否与Clang不兼容,因为它显然还没有将一些TR1库集成到标准中？我在哪里可以获得兼容的Clang …

请考虑以下代码:

#include <vector>
#include <boost/noncopyable.hpp>

struct A : private boost::noncopyable
{
  A(int num, const std::string& name)
    : num(num),
      name(name)
  {
  }

  A(A&& other)
    : num(other.num),
      name(std::move(other.name))
  {
  }

  int num;
  std::string name;
};

std::vector<A> getVec()
{
  std::vector<A> vec;
  vec.emplace_back(A(3, "foo"));
  // vec.emplace_back(3, "foo"); not available yet in VS10?

  return vec; // error, copy ctor inaccessible
}

int main ( int argc, char* argv[] )
{
  // should call std::vector::vector(std::vector&& other)
  std::vector<A> vec = getVec();

  return 0;
}

这并不在VS2010编译,因为很明显A是 …

由于某种原因，我的fakeAsync测试不会解决简单的承诺。我创建了一个显示问题的最小示例（主要是ng生成的样板文件）。

我的被​​测组件在其方法中包含一个简单的直接承诺解析ngOnInit：

import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'app-simple-test',
  templateUrl: './simple-test.component.html',
  styleUrls: ['./simple-test.component.scss']
})
export class SimpleTestComponent implements OnInit {

  constructor() { }

  message: string;

  ngOnInit() {
    Promise.resolve('hello').then((content: string) => this.message = content);
  }

}

我正在通过以下测试来测试这个承诺：

import { async, ComponentFixture, fakeAsync, TestBed, tick } from '@angular/core/testing';

import { SimpleTestComponent } from './simple-test.component';

describe('SimpleTestComponent', () => {
  let component: SimpleTestComponent;
  let fixture: ComponentFixture<SimpleTestComponent>;

  beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [ SimpleTestComponent ]
    }) …
