编译错误:“g ++:错误尝试执行'cc1plus':execvp:没有这样的文件或目录”


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:

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

    You need to install gcc-c++ package.

    yum install gcc-c++

    I had the same issue with gcc "gnat1" and it was due to the path being wrong. Gnat1 was on version 4.6 but I was executing version 4.8.1, which I had installed. As a temporary solution, I copied gnat1 from 4.6 and pasted under the 4.8.1 folder.

    The path to gcc on my computer is /usr/lib/gcc/i686-linux-gnu/

    You can find the path by using the find command:

    find /usr -name "gnat1"

    In your case you would look for cc1plus:

    find /usr -name "cc1plus"

    Of course, this is a quick solution and a more solid answer would be fixing the broken path.

    This problem can happen if different versions of g++ and gcc are installed.

       g++ --version
       gcc --version

    If these don't give the result, you probably have multiple versions of gcc installed. You can check by using:

        dpkg -l | grep gcc | awk '{print $2}'

    Usually, /usr/bin/gcc will be sym-linked to /etc/alternatives/gcc which is again sym-linked to say /usr/bin/gcc-4.6 or /usr/bin/gcc-4.8 (In case you have gcc-4.6, gcc-4.8 installed.)

    By changing this link you can make gcc and g++ run in the same version and this may resolve your issue!

    Each compiler has its own libexec/ directory. Normally libexec directory contains small helper programs called by other programs. In this case, gcc is looking for its own 'cc1' compiler. Your machine may contains different versions of gcc, and each version should have its own 'cc1'. Normally these compilers are located on:


    Similar path for g++. Above error means, that the current gcc version used is not able to find its own 'cc1' compiler. This normally points to a PATH issue.

    I had the same issue when forking with 'python'; the main reason is that the search path is relative, if you don't call g++ as /usr/bin/g++, it will not be able to work out the canonical paths to call cc1plus.
