using dpdk without glibc

using dpdk without glibc

[Nulik Nol]

Hi,
I need to develop an application to forward packets, but it must not
use GLIBC. It will not have malloc(), printf() and other functions
except syscalls. What files should I copy from DPDK distribution that
would allow me to manage the rings ? Is this doable or it will require
rewriting all the code, and probably I should write my own light DPDK
for this purpose ?

Thanks in advance
Nulik

It seems a big challenge.
I think you should be more precise describing the libraries you need. Do you 
need only rings ? For which PMD ?

By the way, what's wrong with glibc ?

If the restriction is size based, have you looked at the smaller libc
variants used in embedded world?
If the restriction  is a legal issue, you need to find a different lawyer...
