Hi Vincent,
Thanks for the updated patch.
I tested this patch on branch master at commit 3daa037.
All of the test-pkg toolchains are failing. In order to have your patch
merged, we should only have "OK" or "SKIPPED".
You can check with the command:
utils/test-pkg -a -p dpdk
I have the output:

Then, you can check build failure logs, for example with:
tail ~/br-test-pkg/arm-aarch64/logfile
In most cases, meson configuration fails with message:
Compiler for C supports arguments -mcpu=: NO
/build/dpdk-24.07/config/meson.build:186:8: ERROR: Problem
encountered: Compiler does not support "" arch flag.
The dpdk meson does not detect the architecture correctly. Maybe
this is introduced by the package patch...
Few other failures are due to incorrect _LICENSE_FILES, see below.
On my side, I was able to have a working configuration, for x86_64.
I think in the current state of the patch, it's probably the only
architecture working. I can have a working dpdk build with the
commands:

This variable should only contains only valid file paths (and no

You can see that by running the command:
make legal-info
It will show the error:

Maybe this is here the correct "cpu_instruction_set" needs to be mapped
to
the correct value: maybe DPDK does not exactly accept what Buildroot is
providing in BR2_GCC_TARGET_ARCH / BR2_GCC_TARGET_CPU. I think this is
the last tricky point to resolve before merging this patch. I'll try to
debug a bit on my side (I would like to have at least the architectures
listed in the _ARCH_SUPPORTS).

Best regards,
Julien.
Hi Julien, Thank you for the checks and helpful hints. I'll review and adjust the supported target CPUs accordingly. For now, let's stick with x86_64 until I can gather a proper build on other GCC target CPUs. I'll make sure to follow your guidelines. Best regards, Vincent
