Hi,
I am seeing an odd compilation error reported from ci/iol testing using this variant
Arch Linux
Kernel: latest
Compiler: gcc latest
https://patches.dpdk.org/patch/75690/
What version of gcc is this build used with exactly so that to be able to reproduce this?
It reports a "maybe-uninitialized" error but I don't see that with any other compiler and from the code I cannot see any branch which would lead to touch undeclared variable.
Thanks and regards,
Nic

Hi Nic,
Doing a gcc --version gives me this result:
gcc (Arch Linux 9.2.1+20200130-2) 9.2.1 20200130
If there is anything I should do to help resolve this issue, please let me know.
Thanks,
Brandon
