我使用Ubuntu 12.04（64位） .

我使用本手册从源代码编译了hipHop：https://github.com/facebook/hiphop-php/wiki/Building-and-installing-HHVM-on-Ubuntu-12.04

hphp运行正常，但我总是看到我的CodeError.js像这样：

[0,{}
]

为了理解发生了什么，我创建了一个“errors.php”文件：

<?php
// just in case
error_reporting(E_ALL);

// undefined variable
$a = $b;

// wrong optional params order
function test($x=false, $y)
{
    // undefined variable
    return $value;
}

// wrong function call
test();

// undefined function call, etc...
test_bad_function();

echo $undefined_variable;
?>

之后，我使用命令使HipHop分析文件：

$HPHP_HOME/src/hphp/hphp  /home/frost/errors.php --output-dir=$OUTPUT_DIR --log=4 --force=1 --keep-tempdir=1 --target=analyze

控制台输出：

HipHop创建了2个文件：Stats.js和CodeError.js

Stats.js内容：

{
"FileCount":1,
"LineCount":21,
"CharCount":363,
"FunctionCount":2,
"ClassCount":0,
"TotalTime":0,
"AvgCharPerLine":17,
"AvgLinePerFunc":10,
"SymbolTypes":
{
    "Array":20,
    "Boolean":8,
    "Double":19,
    "Int64":2248,
    "Object":3,
    "Object - Specific":20,
    "Primitive":13,
    "String":134,
    "Variant":306,
    "_all":2771,
    "_strong":2452,
    "_weak":319
    }
    ,"VariableTableFunctions":[]
}

CodeError.js内容：

[0,{}
]

怎么会这样？我错过了什么？

有趣的事实是：Stats.js每次都会创建，即使我设置了-gen-stats = 0
