/lib64/libc.so.6: version `GLIBC_2.14' not found
So why am I getting GLIBC_2.14 error?
Because your program depends on a symbol with that version, and you are running it on a system which doesn't provide it.
Shouldn't it be 2.19 error?
No.
When a new symbol is introduced, it gets a version assigned to it. Usually that version is the not yet released glibc version, i.e. if the current released version is 2.13, the new symbol gets version 2.14 assigned to it.
That version stays with this symbol (unless a new and incompatible version of the same symbol is introduced later).
The x86_64 GLIBC-2.19 has the following versioned symbols:
$ objdump -T /lib/x86_64-linux-gnu/libc.so.6 | grep ' g ' | head
0000000000078110 g DF .text 0000000000000124 GLIBC_2.2.5 putwchar
0000000000096a70 g DF .text 0000000000000020 GLIBC_2.2.5 __strspn_c1
000000000010a2b0 g DF .text 0000000000000010 GLIBC_2.4 __gethostname_chk
0000000000096a90 g DF .text 000000000000001a GLIBC_2.2.5 __strspn_c2

00000000000fa950 g DF .text 0000000000000021 GLIBC_2.3.2 epoll_create
000000000010a2c0 g DF .text 0000000000000010 GLIBC_2.4 __getdomainname_chk
00000000000fab60 g DF .text 0000000000000021 GLIBC_2.2.5 klogctl
....
That is, if I link a program that calls putwchar, I will need at minimum version 2.2.5, but if my program also calls epoll_create, then I will need a minimum version of 2.3.2.
Your program calls some symbol with version GLIBC_2.14, most likely this one:
0000000000091620 g iD .text 000000000000003d GLIBC_2.14 memcpy
Your program is known to not call any of the symbols below (or you would have gotten a different required version):

What
ldd --verbose simulator
gives ?
I'd say GLIBC2.14 is the minimum required.
What is the version of libc.so on your system ?
