Hi Thomas Monjalon<mailto:thomas@monjalon.net> and Team,
I hope you are doing well.
I wanted to follow up on my earlier request regarding the review of the fix for the DPDK 24.11 and 25.11 compilation issues, which was expected to be available in a future DPDK release.
Could you please confirm when the fix is likely to be available and in which upcoming release, we can expect it?
Thanks & Regards,
Reema Sharma

Hi Thomas Monjalon<mailto:thomas@monjalon.net>,
Thanks for the quick response.
Yes, you understood correctly. I encountered two issues while compiling a C++ application(Radisys CU module) linked with DPDK.
Compiler Version: gcc version 11.4.0 (ubuntu 22.04.3)
Regarding rte_bitops.h:
Disabling the macros works for my current use case, so I can proceed with that approach for now.
I agree that the behaviour of the __RTE_BIT_OVERLOAD macros needs further analysis, It will be great if fix for this will be available in next DPDK release. Please find the error details for your reference:
dpdk/dpdk-25.11/x86_64-native-linuxapp-gcc/include/rte_bitops.h:1468:1: error: conflicting declaration of C function ‘bool rte_bit_test(const volatile uint32_t*, unsigned int)’
1468 | rte_bit_ ## family ## fun(qualifier uint ## size ## _t *addr, arg1_type arg1_name) \
| ^~~~~~~~
dpdk/dpdk-25.11/x86_64-native-linuxapp-gcc/include/rte_bitops.h:1468:1: note: in definition of macro ‘__RTE_BIT_OVERLOAD_V_2R’
1468 | rte_bit_ ## family ## fun(qualifier uint ## size ## _t *addr, arg1_type arg1_name) \
| ^~~~~~~~
dpdk/dpdk-25.11/x86_64-native-linuxapp-gcc/include/rte_bitops.h:1479:9: note: in expansion of macro ‘__RTE_BIT_OVERLOAD_SZ_2R’
1479 | __RTE_BIT_OVERLOAD_SZ_2R(family, fun, qualifier, 32, ret_type, arg1_type, arg1_name) \
| ^~~~~~~~~~~~~~~~~~~~~~~~
Regarding rte_cryptodev.h:
This issue is not observed with DPDK 25.11. Please disregard the earlier report.
Thanks & Regards,
Reema Sharma

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?
