title: How do I install glibc 2.12 in ubuntu 12.04?
body: <p>I have a 64-bit ubuntu 12.04 installation， with a glibc version 2.15, but the machine I need to run on has a glibc version 2.12, when I ran the program compiled on my own machine on the target machine, it gave me an error: version 'GLIBC_2.14' not found.</p>
  
  <p>It is impossible to upgrade the target machine's glibc, so I think maybe I can install another  glibc in my machine.</p>
  
  <p>Until now, I have tried to downloaded the source of glibc2.12 to make and make install, but I got some syntax error in the source, maybe it's because that the version of my gcc is higher than glibc2.21 needs.</p>
  
  <p>And now I am trying to install a older distribution by chroot way, but I have not made it.</p>
  
  <p>Do you have some proposals?</p>
  
  <p>Thank you.</p>
