HipHop编译器无法识别对象$this变量

Question

我是HipHop的新手，我正在尝试编译和运行一个自定义的PHP应用程序，编译错误日志文件包含数百个与$this变量"未声明"有关的错误。。这里有一个简化的例子：-

file-bar.hp:

class Bar {
     private $_baz = 'Hello';
     public function __construct() {
         echo 'Constructed';
     }
     public function foo() {
         echo $this->_baz;
     }
}
$bah = new Bar();
$bah->foo();

该文件被列为列表文本文件f.lst中的唯一条目，并且HipHop编译器被调用。。。

root@hiphop:/home/rich/www# hhvm --hphp --input-list=f.lst -k 1 --log=3

生成的JSON错误日志/tmp/hhp_rC60VL/CodeError.js-包含以下内容：-

[1,{"UseUndeclaredVariable":[{"c1":["bar.php",11,8,11,12]
 ,"d":"$this"}
]
}
]

我是不是遗漏了一些显而易见的东西？

TIA

Answer 1

自从我发布问题后，我在GitHub上提出了一个问题，并被告知他们已经修复了导致该问题的错误->https://github.com/facebook/hiphop-php/issues/698-我被转移到了其他事情上，所以我还没有机会验证这一点，但我认为现在一切都好了。

这是在HHVM上吗？尝试你的例子对我来说在HHVM上运行得很好。
