I don't understand why removing a function like rte_snprintf() in a new version of DPDK would be a problem. Yes, it would break the build of external applications, but that's the best way to fix the problem in the external code. Adding a compatibility layer just delays the issue. Maybe having a line about this in a "release note" or a "porting guide" would be enough? It could even references the commit id, showing how to solve the issue. About the -Werror flag, I would say that removing it is not a good idea. From my experience, many issues are pointed out by warnings, and forcing the compiler to stop on warning helps to have better code quality. Regards, Olivier
