Undefined reference to GLIBC_2.15

I have a project that shows the following error in the link:

/usr/lib/i386-linux-gnu/libpython2.7.so: undefined reference to '__fdelt_chk@GLIBC_2.15'

      

        
        
        
      

    

I am using Ubuntu 14.04 which has libc6 (GLIBC_2.19) installed. I cannot understand this problem and have not found a solution.
