php - Compile error: "g++: error trying to exec 'cc1plus': execvp: No such file or directory"

Question

When I compile C/C++ program with popen in php... I got this error:

g++: error trying to exec 'cc1plus': execvp: No such file or directory

but if I run php code in shell.. it works fine..

in Arch Linux..

PHP Code:

<?php
    function rfile($fp) {
    $out="";
       while (!feof($fp)) {
           $out.= fgets($fp, 1024000);
       }
       return $out;
    }
    $p = popen('g++ -Wall -g aplusb.cc -o aplusb 2>&1', 'r');
    $result = rfile($p);
    pclose($p);
    echo $result;
?>

thanks

You need to install gcc-c++ package.

yum install gcc-c++
