[v5] eal: arm: fix out of tree build
Checks
Commit Message
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.

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.

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")
