How to fix this error:
/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.14' not found
Linux alef 3.2.0-4-amd64 #1 SMP Debian 3.2.35-2 x86_64 GNU/Linux
That means the program was compiled against glibc version 2.14, and it requires that version to run, but your system has an older version installed. You'll need to either recompile the program against the version of glibc that's on your system, or install a newer version of glibc (the "libc6" package in Debian).
Debian has glibc 2.16 in the "experimental" repository, but recompiling the program is the safer option. Glibc is the library that everything depends on, so upgrading it can have far-reaching implications. Although there's probably nothing wrong with Debian's glibc 2.16 package, the fact that it's in the experimental repository means it hasn't received as much testing.
I have posted my solution here, repost it for reference.
In my situation, the error appears when I try to run an application (compiled on Ubuntu 12.04 LTS) using GLIBC_2.14 on Debian Wheezy (which installs glibc 2.13 by default).
I use a tricky way to run it, and get correct result:
I don't know whether it will work successfully for other applications. Wish it helpful.
