Re: [dpdk-dev] Using valgrind with DPDK app

[Victor Huertas <vhuertas@gmail.com>]

Hello,

I have exactly the same problem as you. I have also downloaded, compiled
and installed the very last version of valgrind (v3.17).
As soon as the mempool is created, the program gets stuck.

If valgrind cannot be used with DPDK (I am using v18.11.5) as memory leak
debugger, there must be other tool to do it. Which one?

Thanks for your attention
