Including rte_byteorder.h may fail for ARM builds with 'Platform must
be built with RTE_FORCE_INTRINSICS' if rte_config.h is not included
before. Include rte_config.h from rte_byteorder.h to solve the issue.

Since -include rte_config.h added by meson, This issue is not coming
with in tree build.
IMO, Fix is correct.

Please send v2 with
- Add Fixes: tag and Cc: stable@dpdk.org so that i can be backported
to stable tree.
- Fix following checkformat.sh warning

Wrong headline format:
        eal: add include for rte_byteorder on ARM
Wrong headline case:
                        "eal: add include for rte_byteorder on ARM": ARM --> Arm

- Subject could be "eal: arm: fix out of tree build" or so.

With above change:

Moving of this section solves the problem.

rte_config.h is included by rte_common.h in above line.

I see similar issue in rte_atomic32.h/rte_atomic64.h/rte_spinlock.h/rte_ticketlock.h/rte_mcslock.h in lib/eal/arm/include.
Do you want to fix all these?
Thanks.

Including various headers may fail for ARM builds with 'Platform must
be built with RTE_FORCE_INTRINSICS' if rte_config.h is not included
before. Move the error message after the includes to ensure rte_config.h
is always included.

Thanks for the patch.
More fix lines should be added:
Fixes: 17d5fa0fa90d ("eal/arm: add atomic operations for ARMv7")
Fixes: d708f01b7102 ("eal/arm: add atomic operations for ARMv8")
Fixes: 2173f3333b61 ("mcslock: add MCS queued lock implementation")
Fixes: 7860c3965483 ("eal/arm: add spinlock operations for ARM")
Fixes: ca49b92079df ("ticketlock: enable generic ticketlock on all arch")

Including various headers may fail for ARM builds with 'Platform must
be built with RTE_FORCE_INTRINSICS' if rte_config.h is not included
before. Move the error message after the includes to ensure rte_config.h
is always included.

Fixes: de966ccdcd7f ("eal/arm: add byte order operations for ARM")
Fixes: 17d5fa0fa90d ("eal/arm: add atomic operations for ARMv7")
Fixes: d708f01b7102 ("eal/arm: add atomic operations for ARMv8")
Fixes: 2173f3333b61 ("mcslock: add MCS queued lock implementation")
Fixes: 7860c3965483 ("eal/arm: add spinlock operations for ARM")
Fixes: ca49b92079df ("ticketlock: enable generic ticketlock on all arch")

v5:
* Add Fixes: tag.

v4:
* Apply to fix to rte_atomic_{32,64}.h, rte_{mcs,spin,ticket}lock.h as
  well.
* Remove unnecessary include of rte_config.h.
* Adjust commit message.

v3:
* Proper in-reply-to.

v2:
* Fixed subject line.

The header check currently compiles all headers with an implicit
"-include rte_config.h".
I suppose this is because it comes from the project level meson configuration.

Would there be a way to detect the issue fixed by this patch?

I'm not convinced that there is an issue here. For DPDK compiles
rte_config.h must always be included first, which is why it's included in
the cflags reported by pkg-config. If we do want to move away from having
rte_config as an omnipresent first include, we need to update many DPDK
headers to explicitly include it.

the issue came up in our (rather large) DPDK app. Our build process uses a
hand-crafted build system (based on ninja) for native and cross builds, i.e.
pkg-config is not involved. It basically throws "-isystem <our-target-
prefix>/include/dpdk" into the compiler and omits linking some of the DPDK libs
not used by us.

This worked fine for us, and has no issues for x86 targets. I guess because
most headers do include rte_config (or rte_common) at least transitively before
doing anything else. Anyway, if you regard "-include rte_config.h" as the way
to go, this is fine for me. Its a one-liner for us and we can probably drop the
patch then.

Regards
Michael

As what I can find, no issues for x86 because it has been fixed in commit:
0d440d081ca1 ("lib: fix missing includes in exported headers")
