Re: Request for Review of Fixes Applied for DPDK 24.11 and 25.11 Compilation Errors

[Thomas Monjalon]

Hello,

If I understand well, you hit 2 issues while compiling a C++ app linked with 
DPDK?
Could you share the exact version of your compiler?

For rte_bitops.h, if disabling these macros is OK for you, go with it for now.
We will need to understand what happens exactly with __RTE_BIT_OVERLOAD macros.

For rte_cryptodev.h, it may be hiding an issue somewhere else.
Please could you share the exact error message?
