Question

我正在尝试从python脚本abc.py执行二进制（my_binary），如下所示。

    import os
    import sys
    import logging
    from subprocess import Popen, PIPE
    logging.basicConfig(level=logging.DEBUG,format='%(asctime)s %
    (levelname)-8s %(message)s',datefmt='%a, %d %b %Y 
    %H:%M:%S',filename='/var/home/root/root.txt',filemode='w')

    os.environ["ABCDE"]="x.x.x.x"
    os.environ["USER"]="user"
    os.environ["PASSWORD"]="password"

    p1 = Popen(["/var/home/root/my_binary","exec"], stdout=PIPE, stderr=PIPE)
    out, err=p1.communicate()
    logging.info(out)
    return out,err

    if __name__ == '__main__':
         out,err = run(sys.argv[1:])
         logging.info(out)
         if( out.strip() == "Success: Check:"):
         print "Success: OK:"

如果我直接在终端上执行这个abc.py python程序，那么二进制my_binary将被执行。

但是当我尝试从另一个c ++（使用上述类似方式的管道）程序（比如xyz.cpp）运行程序时，my_binary无法执行。

注意：

  The xyz.cpp is built with gcc(libstdc++.so.7).

  The my_binary is built with gcc(libstdc++.so.6).

  my_binary is built with "-D_GLIBCXX_USE_CXX11_ABI=0" as the .so used in 
  my_binary are built using older g++(v 4.5).

所有必需的共享库和静态库都存在于env。

任何帮助都将不胜感激。

感谢。

子进程执行失败，使用std :: basic_string <char，std :: char_traits <char =“”>，std :: allocator <char>＆gt; :: basic_string
